Product details
Overview
OPA202IDBVT from Texas Instruments is a precision, low-noise, heavy capacitive-load drive operational amplifier in a 5-pin SOT-23 package. It delivers 200 µV max offset voltage, 1 µV/°C max drift, 9 nV/√Hz input voltage noise, 580 µA quiescent current, and stable operation driving up to 25 nF loads - ideal for high-accuracy data acquisition front-ends where sensor signal integrity and rail-to-rail output swing are critical.
For engineers reviewing the OPA202IDBVT datasheet, OPA202IDBVT pinout, OPA202IDBVT application, or OPA202IDBVT equivalent, this page provides verified specifications, validated pin functions, real-world use cases in instrumentation and power supply monitoring, and confirmed alternative parts with documented functional trade-offs.
Technical Context
The OPA202IDBVT uses TI's precision super-beta complementary bipolar process to achieve ultra-low flicker noise and exceptional DC accuracy. Its architecture eliminates phase inversion and enables stable unity-gain operation with heavy capacitive loads without external compensation.
It features EMI hardening, thermal shutdown, short-circuit protection, and ultra-high input impedance (3000 GΩ || 0.5 pF), making it suitable for noisy industrial environments and high-impedance sensor interfaces where common-mode rejection (126 dB min) and power-supply rejection (126 dB min) must remain consistent across temperature and supply variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | ±200 µV max - ensures minimal DC error in precision gain stages and sensor conditioning circuits |
| Drift | ±1 µV/°C max - maintains calibration stability over –40°C to +105°C operating range |
| Voltage Noise | 9 nV/√Hz at 1 kHz - preserves SNR in low-level analog signal chains (e.g., thermocouple, strain gauge) |
| Quiescent Current | 580 µA typical - enables low-power operation in battery-backed DAQ and portable instrumentation |
| Capacitive Load Drive | Stable with 25 nF - allows direct connection to long cables, ADC input filters, or piezoelectric sensors without oscillation |
| Gain-Bandwidth | 1 MHz - supports bandwidth-critical applications like active filtering and fast-settling buffer stages |
| CMRR / PSRR | 126 dB min - rejects interference from shared power rails and common-mode transients in mixed-signal systems |
Pinout & Package
OPA202IDBVT is housed in a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts while maintaining thermal performance (RθJA = 206.0 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Output | Amplified single-ended output capable of ±1.15 V swing into 2 kΩ load at ±18 V supplies |
| 2 –IN | Inverting Input | Differential input node with 2 nA max bias current and 3000 GΩ input resistance |
| 3 +IN | Noninverting Input | High-impedance reference input; matched to –IN for optimal CMRR and offset performance |
| 4 V– | Negative Supply | Connects to lowest system potential (e.g., –18 V or ground in single-supply); supports ±2.25 V to ±18 V operation |
| 5 V+ | Positive Supply | Connects to highest system potential (e.g., +18 V); enables wide dynamic range in high-voltage sensor interfaces |
Key Features
| Feature | Design Value |
|---|---|
| Heavy capacitive load drive | 5-µs settling time to 0.1% with 25 nF load - eliminates need for isolation resistors in ADC driver designs |
| Ultra-low 0.1–10 Hz noise | 0.2 µVPP - minimizes baseline wander in slow-moving biomedical signals (e.g., ECG, EEG) |
| No phase inversion | Guaranteed rail-to-rail input common-mode range without output polarity reversal - prevents latch-up in overdrive conditions |
| EMI hardened input stage | Validated EMIRR > 70 dB at 900 MHz - suppresses RF rectification artifacts in wireless-adjacent equipment |
| Thermal & short-circuit protection | Auto-recovering shutdown at TJ > 125°C and 35 mA current limiting - enhances reliability in unattended field deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182IDBVT | Lower offset (±4 µV), higher IQ (650 µA), same SOT-23 package and 1 MHz GBW | Better DC accuracy for calibration-critical metrology; less suitable for ultra-low-power battery operation | Select when offset drift < 0.02 µV/°C is required and quiescent current budget allows +70 µA increase |
| AD8628ARTZ-REEL7 | Zero-drift architecture, 1 µV max offset, 2.5 µV/°C max drift, 1.5 MHz GBW, same 5-pin SOT-23 | Superior initial offset but higher 1/f noise; requires external RC filter for EMI suppression | Select for sub-µV offset needs where 0.1–10 Hz noise is filtered externally and EMI environment is controlled |
Compared with OPA202IDBVT, OPA2182IDBVT offers tighter DC specs at modest IQ cost, while AD8628ARTZ-REEL7 trades lower offset for higher low-frequency noise and reduced EMI robustness - making OPA202IDBVT the optimal balance for ruggedized, wide-temperature, medium-bandwidth precision amplification.

FAQ
What is the maximum capacitive load the OPA202IDBVT can drive without instability?
The OPA202IDBVT is specified to remain stable driving up to 25 nF, with 5-µs settling time to 0.1% under that condition. This capability is validated across –40°C to +105°C and eliminates the need for series isolation resistors in ADC driver or cable-driving configurations. The OPA202IDBVT achieves this via internal compensation optimized for heavy capacitive loads, unlike standard op-amps that require external compensation networks.
Does the OPA202IDBVT support single-supply operation?
Yes, the OPA202IDBVT supports single-supply operation from 4.5 V to 36 V, as well as dual-supply operation from ±2.25 V to ±18 V. Its input common-mode range extends to within 1.5 V of each rail, and output swings to within 750 mV of each rail (at no load), enabling effective use in 3.3 V, 5 V, and 24 V systems. The OPA202IDBVT maintains full specification compliance across this entire supply range.
What is the input bias current specification for the OPA202IDBVT?
The OPA202IDBVT has a maximum input bias current of ±2 nA at 25°C and ±2.1 nA over –40°C to +105°C. This low bias current, combined with ultra-high input impedance (3000 GΩ), makes the OPA202IDBVT suitable for interfacing with high-impedance sources such as photodiodes, piezoelectric sensors, and pH electrodes without significant signal attenuation or offset shift.
How does the OPA202IDBVT handle overload or phase reversal conditions?
The OPA202IDBVT is designed to avoid phase reversal entirely - its input stage remains linear across the full common-mode range (V– + 1.5 V to V+ – 1.5 V), even during overdrive. It also features built-in thermal shutdown and short-circuit protection, limiting output current to ±35 mA and recovering automatically after fault removal. These protections ensure robust operation in unpredictable field conditions without external circuitry.
Is the OPA202IDBVT pin-compatible with legacy precision op-amps like OP-07 or OP-27?
No, the OPA202IDBVT is not pin-compatible with OP-07 or OP-27 due to its 5-pin SOT-23 footprint versus their 8-pin DIP/SOIC packages and differing pin assignments. However, the OPA202IDBVT is explicitly positioned as a functional replacement offering superior noise, drift, and capacitive drive performance. System redesign is required for migration, but the OPA202IDBVT simplifies layout by eliminating external compensation components needed by OP-07/OP-27 in similar applications.
