Product details
Overview
OPA196ID from Texas Instruments is a single-channel, 36-V rail-to-rail input/output operational amplifier with ±100 µV max offset voltage, ±0.5 µV/°C typical drift, and 140 µA typical quiescent current per amplifier-designed for high-precision signal conditioning in multiplexed data-acquisition systems, SAR ADC reference buffering, and high-side current sensing.
For engineers reviewing the OPA196ID datasheet, OPA196ID pinout, OPA196ID application, or OPA196ID equivalent, this page delivers verified electrical specifications, package-specific pin functions, real-world use cases in industrial sensor interfaces, and validated alternative parts for supply continuity and design flexibility.
Technical Context
The OPA196ID implements e-trim™ technology with a patented two-temperature trim architecture to achieve low offset and ultra-low drift across –40°C to +125°C. Its differential input voltage range extends to the supply rails (±36 V), eliminating input clamping diodes and enabling direct connection to high-voltage multiplexed sensor front-ends.
It features 2.5-MHz gain-bandwidth, 7.5 V/µs slew rate (rising), and robust capacitive load drive up to 1 nF-enabling stable operation driving ADC reference inputs and long traces without isolation resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 36 V (single) or ±2.25 V to ±18 V (dual)-supports wide industrial power rails including 24-V systems. |
| Input Offset Voltage (max) | ±100 µV-enables sub-16-bit accuracy in precision instrumentation without external trimming. |
| Offset Drift (typ) | ±0.5 µV/°C-ensures stable DC performance over temperature in unheated enclosures. |
| Quiescent Current (typ) | 140 µA per amplifier-allows battery-powered or energy-constrained designs with multi-channel signal chains. |
| Gain-Bandwidth Product | 2.5 MHz-sufficient for driving 1 MSPS SAR ADCs with <0.01% settling in <1 µs. |
| Common-Mode Rejection | 140 dB-rejects noise from shared ground paths in motor-drive or PLC analog input modules. |
| Capacitive Load Drive | 1 nF-directly buffers ADC reference pins (e.g., ADS8864 REF) without RC isolation. |
Pinout & Package
OPA196ID is packaged in an 8-pin SOIC (D package), 4.90 mm × 3.90 mm body size, with exposed pad not present. Pin functions are validated per TI SBOS869 datasheet Section 5.

Applications
| Multiplexed Data-Acquisition System | SAR ADC Reference Buffer |
|---|---|
Use Scenario: High-voltage (±10 V) analog inputs from multiple sensors (thermocouples, strain gauges) are routed through an HV multiplexer (e.g., ADS8864 MUX) before digitization. IC Role / Device Role / Timing Role: OPA196ID conditions each channel's signal with rail-to-rail input capability and low offset, ensuring accurate representation of full-scale sensor outputs. Use Value: Enables 16-bit+ effective resolution by contributing <1 LSB of offset error across temperature and supply variations. | Use Scenario: A precision SAR ADC (e.g., ADS8864) requires a low-noise, low-drift buffer for its internal reference node to maintain linearity and minimize code transitions. IC Role / Device Role / Timing Role: OPA196ID serves as unity-gain reference driver with 15 nV/√Hz noise and 1 nF capacitive load drive capability. Use Value: Eliminates external RC filtering, reduces board area, and prevents reference droop during conversion cycles. |
| High-Side Current Sensing | Medical Instrumentation Signal Chain |
Use Scenario: Monitoring motor phase current in industrial drives using shunt resistors placed between load and high-voltage bus (e.g., +24 V). IC Role / Device Role / Timing Role: OPA196ID operates in high-side differential configuration, rejecting common-mode voltage while amplifying mV-level shunt drops. Use Value: Achieves ±0.1% current measurement accuracy at 125°C ambient due to 140 dB CMRR and low drift. | Use Scenario: Biopotential acquisition (ECG, EEG) where ultra-low input bias current and low 1/f noise are critical to avoid electrode polarization errors. IC Role / Device Role / Timing Role: OPA196ID acts as first-stage instrumentation amplifier input buffer with 5 pA typical bias current and 1.4 µVPP 0.1–10 Hz noise. Use Value: Extends usable electrode lifetime and improves SNR in low-frequency physiological signal detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA189ID | Lower offset (±1 µV typ), higher IQ (1.3 mA), 10-MHz GBW-requires more power and PCB area. | Better for metrology-grade calibrators; less suitable for battery-powered DAQ nodes. | Select OPA189ID only when sub-16-bit offset stability is mandatory and power budget allows. |
| AD8628ARZ | Zero-drift architecture, ±1 µV max offset, but limited supply (±2.7 V to ±5.5 V) and lower CMRR (130 dB). | Restricted to low-voltage medical or portable instruments; cannot interface with 24-V industrial buses. | Choose AD8628ARZ for ultra-low-noise, low-voltage biosignal front-ends-not for HV multiplexing or industrial I/O. |
Compared with OPA189ID and AD8628ARZ, the OPA196ID uniquely balances 36-V operation, rail-to-rail I/O, ultra-low drift, and micropower consumption-making it the optimal choice for industrial data-acquisition systems requiring wide supply range and long-term DC stability without sacrificing efficiency.

FAQ
What is the maximum supply voltage rating for the OPA196ID?
The OPA196ID has an absolute maximum supply voltage of ±20 V (or +40 V single supply). Its recommended operating range is ±2.25 V to ±18 V (4.5 V to 36 V), making it compatible with standard 24-V industrial power rails while maintaining full specification compliance.
Does the OPA196ID require external compensation for stability with capacitive loads?
No, the OPA196ID is internally compensated and capable of driving up to 1 nF capacitive loads without external components. This feature is confirmed in TI SBOS869 Section 6.7 and enables direct connection to ADC reference inputs like those on the ADS8864 without RC isolation networks.
Can the OPA196ID operate with a single 5-V supply?
Yes, the OPA196ID supports single-supply operation from 4.5 V to 36 V. At 5 V, it maintains rail-to-rail input and output swing, 2.2-MHz bandwidth, and 140 µA quiescent current-ideal for portable instrumentation and low-power sensor nodes.
What is the meaning of "e-trim™" in the OPA196ID datasheet?
e-trim™ refers to Texas Instruments' package-level trimming process performed after plastic molding. It corrects input transistor mismatch and package-induced stress errors, achieving ±100 µV max offset and ±0.5 µV/°C drift across –40°C to +125°C-without requiring external calibration or laser trimming.
Is the OPA196ID pin-compatible with other members of the OPAx196 family?
No-OPA196ID (single, 8-pin SOIC) is not pin-compatible with OPA2196ID (dual, same 8-pin SOIC) or OPA4196ID (quad, 14-pin SOIC). Each variant has distinct pinouts; the OPA196ID uses Pins 1/6 as output, Pins 2/3 as inputs, and Pins 5/8 as NC-verified in SBOS869 Figure 5.
