Product details
Overview
OPA196IDBVT 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, low-power industrial sensing and data-acquisition front-ends.
For engineers reviewing the OPA196IDBVT datasheet, OPA196IDBVT pinout, OPA196IDBVT application, or OPA196IDBVT equivalent, this page delivers verified specifications, package-specific pin functions, real-world use cases in multiplexed ADC systems and current sensing, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The OPA196IDBVT implements e-trim™ technology with a patented two-temperature trim architecture, achieving ±25 µV typical offset and ultra-low drift across –40°C to +125°C. Its differential input voltage range extends to the supply rails (±20 V), eliminating input clamping diodes and enabling direct connection to high-voltage multiplexed sensor nodes.
It features 2.5-MHz gain-bandwidth, 7.5 V/µs slew rate (rising), and robust 1-nF capacitive load drive-enabling stable operation driving SAR ADC reference buffers and high-side current-sense amplifiers without external isolation resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.5 V to 36 V (single) or ±2.25 V to ±18 V (dual); supports wide-input industrial rails without level-shifting. |
| Input Offset Voltage | ±100 µV (max); enables sub-0.01% accuracy in 16-bit+ precision measurement paths. |
| Offset Drift | ±0.5 µV/°C (typ); ensures <1 µV total drift over 85°C ambient range-critical for uncalibrated field instruments. |
| Quiescent Current | 140 µA per amplifier (typ); allows battery-powered or energy-harvested sensor nodes to operate >10 years on coin cells. |
| CMRR | 140 dB (typ at 25°C); rejects common-mode noise from motor drives or long-line sensor cables in noisy factory environments. |
| Capacitive Load Drive | 1 nF (guaranteed); directly buffers SAR ADC reference inputs (e.g., ADS8864) without stability-compromising RC networks. |
| Output Swing | Rail-to-rail; delivers full 34.5 Vpp output swing at 36 V supply-maximizing dynamic range into high-resolution ADCs. |
Pinout & Package
VSSOP-8 (DGK) package: 3.0 mm × 3.0 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected). Pin 1 marked by dot; pin numbering counterclockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | Noninverting input | High-impedance (10¹³ Ω || 6.4 pF) node; accepts signals up to V+ + 0.1 V-supports rail-to-rail common-mode range. |
| –IN | Inverting input | Differential input pair node; supports full 36-V differential input range (V+ – V– + 0.2 V) without phase reversal. |
| OUT | Amplifier output | Class-AB output stage delivering ±65 mA short-circuit current; drives 2-kΩ loads within 15 mV of rails. |
| V+ | Positive supply | Highest potential supply rail; must be ≥ V– + 4.5 V; powers internal bias and output stages. |
| V– | Negative supply | Lowest potential supply rail; may be ground in single-supply configurations; sets lower common-mode limit. |
| NC (Pins 1, 5, 8) | No internal connection | Unused pins; must be left floating-no tie to V+, V–, or ground required for stability or performance. |
Key Features
| Feature | Design Value |
|---|---|
| e-trim™ two-temperature calibration | Reduces initial offset to ±25 µV typ and drift to ±0.5 µV/°C-eliminates system-level trimming in medical and test equipment. |
| Rail-to-rail input & output | Enables direct interfacing with 0–36 V sensor outputs and full utilization of 36-V ADC reference ranges. |
| EMI/RFI filtered inputs | Integrated RC filtering suppresses >100 MHz RF interference-critical for EMC-compliant industrial PLC modules. |
| High capacitive load drive (1 nF) | Stable operation into ADC reference decoupling caps without series resistance-reduces BOM count and layout area. |
| Differential input range to supply rail | Accepts VIN+ = V+ and VIN– = V– simultaneously-enables true high-side current sensing without external level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA192IDBVT | Lower input bias current (±0.3 pA vs ±5 pA), higher GBW (10 MHz vs 2.5 MHz), higher IQ (1 mA vs 140 µA). | Better for ultra-high-impedance pH or photodiode sensors; unsuitable for battery-powered designs due to 7× higher quiescent current. | Select OPA192IDBVT only when femtoampere bias and 10-MHz bandwidth are mandatory-and power budget permits. |
| OPA2333AIDBVR | Zero-drift architecture (0.02 µV/°C drift), lower noise (10 nV/√Hz), but limited supply (1.8–5.5 V) and output drive (±25 mA). | Optimized for low-voltage, ultra-stable DC measurements (e.g., weigh scales); cannot interface with 24-V industrial buses or drive heavy ADC references. | Choose OPA2333AIDBVR for sub-5-V, zero-drift-critical applications-but not for 36-V industrial signal chains. |
Compared with OPA192IDBVT and OPA2333AIDBVR, the OPA196IDBVT uniquely balances 36-V operation, ultra-low drift, and micropower consumption-making it the only viable option for battery-operated, high-voltage sensor nodes requiring <1 µV/°C total drift over industrial temperature ranges.

FAQ
What is the maximum supply voltage for OPA196IDBVT?
The OPA196IDBVT supports absolute maximum supply voltages of ±20 V (dual) or +40 V (single), with recommended operation from ±2.25 V to ±18 V or 4.5 V to 36 V. Exceeding ±20 V risks permanent damage per TI's Absolute Maximum Ratings table in SBOS869.
Does OPA196IDBVT require external compensation for stability?
No-OPA196IDBVT is unity-gain stable and requires no external compensation components. Its internal compensation supports stable operation with capacitive loads up to 1 nF, making it ideal for direct connection to ADC reference inputs and filter networks without added resistors or capacitors.
Can OPA196IDBVT drive the reference input of ADS8864?
Yes-OPA196IDBVT is explicitly used in TI's ADS8864 reference design as the reference buffer stage. Its 1-nF capacitive load drive, 15 nV/√Hz noise, and rail-to-rail output ensure fast, low-noise settling into the ADS8864's reference pin without droop or distortion.
What is the thermal shutdown behavior of OPA196IDBVT?
OPA196IDBVT includes thermal protection that activates at 180°C junction temperature, reducing output current to prevent damage. Thermal hysteresis is 30°C, so recovery occurs at ~150°C. This protects against sustained overload in enclosed industrial enclosures without external thermal monitoring.
Is OPA196IDBVT pin-compatible with other OPAx196 variants?
No-OPA196IDBVT (single, SOT-23-5) uses a 5-pin DBV package with different pinout than OPA2196 (dual, SOIC-8/VSSOP-8) or OPA4196 (quad, SOIC-14/TSSOP-14). The DBV pinout has dedicated +IN, –IN, OUT, V+, and V– terminals with three NC pins-requiring unique PCB layout.
