Quick Answer
OPA192ID is TI's single-channel precision operational amplifier in an eight-pin SOIC package with tube presentation. It supports a 4.5 to 36 V total supply and rail-to-rail input and output. The family targets precision analog work where DC error, source loading and dynamic response need to be considered together.
The headline 5 microvolt offset is a typical figure, not a universal worst-case guarantee. A sourcing guide should preserve that distinction because it directly affects the approved error budget. Match the exact ID package and carrier to the released board, and obtain commercial terms through a current written quotation.
- Requested device: OPA192 single amplifier, D-package SOIC8, tube carrier.
- Engineering approval: use electrical limits and their conditions, with typical figures clearly distinguished.
Key Specifications
TI's ordering page lists the D package with eight pins and an operating temperature range from minus 40 to plus 125 degrees Celsius. The same page distinguishes the tape-and-reel IDR option. Keep those carrier details visible in procurement records rather than collapsing both options into the family name.
The family includes single, dual and quad amplifiers. A common package pin count is not proof of the same channel arrangement: the single and dual devices need their own pin diagrams. Have the schematic owner check the actual signal and supply connections whenever a supplier proposes a different member.
- DC precision: TI identifies typical offset of 5 microvolts and typical drift of 0.2 microvolts per degree Celsius; use guaranteed limits for worst-case budgeting.
- Dynamic behavior: the 10 MHz gain-bandwidth figure is a starting point for selecting gain and response time, not a complete settling specification.
- Supply and signals: verify the total rail voltage, input common-mode range and load-dependent output swing under the intended conditions.
Where to Use This Part
A precision control-voltage buffer is a useful example. Write down the smallest commanded change that matters and the maximum error tolerated at the receiving circuit. Allocate that error across the reference, amplifier, resistor network, wiring and converter. This exposes whether a low typical offset meaningfully improves the complete product.
Temperature testing should reflect the measurement objective. A room-temperature calibration may remove part of an initial offset while leaving drift and gain changes relevant. Define the calibration procedure and required operating range before comparing candidate amplifiers. Keep measured results associated with the exact circuit, component values and calibration state.
If the buffer drives a capacitive load, assess stability and settling with the real cable, filter and receiving input. Use both small and large signal steps and examine recovery after allowed overload conditions. The manufacturer's capacitive-load discussion guides circuit design, but the final acceptance decision should be based on the actual assembled signal path.
- Precision control outputs: evaluate static error and response when the downstream load changes.
- Measurement conditioning: connect the amplifier budget to reference accuracy, resistor ratios and calibration strategy.
- High-impedance analog sources: include input bias effects, board leakage and contamination in the measured error.
Pricing and Lead Time
Request OPA192ID using the complete code and specify whether the manufacturing line accepts tubes. TI identifies OPA192IDR as the related tape-and-reel presentation, so any such proposal should be explicit. Ask manufacturing to approve carrier handling before the purchasing line is changed.
The RFQ should include quantities for evaluation and production separately, the required destination and the documentation expected at receiving. Where lot continuity matters to a calibration study, state that need in measurable terms and ask the supplier to confirm the proposed arrangement. Avoid leaving acceptance criteria hidden in an informal description such as precision grade.
Obtain price basis, currency, quote validity and a delivery schedule tied to quantities. Ask for the offered manufacturer code and packaging condition with each response. If the supply proposal changes after review, request an updated quotation showing the changed fields so engineering can determine whether another approval is necessary.
At receiving, reconcile the purchase order, package label and lot record. Keep calibration or functional test results connected to the boards built from that material. These recommended controls do not imply that a quoted lot has already passed a particular test or that a seller has committed to a specific arrival date.
Common Alternatives
When another amplifier is proposed, begin with the requirement that caused the search. A lower typical offset may not improve the design if its worst-case drift or input-current behavior is less suitable. Compare values at the relevant supply, common-mode voltage, temperature and load rather than selecting the smallest number in a summary table.
A dual or quad family member is an architectural option when the board needs more channels, but it changes pin mapping and potentially routing. Document how unused channels are handled and how each active channel is tested. Similar electrical branding does not remove those practical design tasks.
For a different precision family, include noise over the application's bandwidth, input protection behavior, output drive and stability. Evaluate the candidate with the existing gain and filter network, then identify any changes needed to meet the same acceptance limits. Capture those dependencies in the engineering change record.
Purchasing can then compare the complete cost: component terms, board changes, calibration work and verification. Release an alternate only when its full ordering number and approved circuit revision are linked, so future buyers can reproduce the decision without repeating an undocumented experiment.
FAQ
Is the 5 microvolt offset a guaranteed maximum?
No. TI identifies that headline value as typical. Consult the electrical-characteristic limits and conditions when calculating worst-case measurement or control error.
Are OPA192ID and OPA192IDR identical carrier requests?
They are different purchasing presentations: TI lists ID in tubes and IDR on tape and reel. Confirm the accepted presentation and exact supplied code with manufacturing.
Can an eight-pin dual amplifier be accepted because the package matches?
Pin count and outline alone are insufficient. Check the channel arrangement, pin functions and full electrical behavior against the schematic before approving any proposed change.
