Product details
Overview
OPA202IDBVR 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 maximum 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 sensor signal conditioning in portable instrumentation.
For engineers reviewing the OPA202IDBVR datasheet, OPA202IDBVR pinout, OPA202IDBVR application, or OPA202IDBVR equivalent, key selection criteria include its ±2.25 V to ±18 V dual-supply range, 1 MHz gain-bandwidth product, ultra-high 3000 GΩ input impedance, EMI-hardened architecture, and guaranteed performance across –40°C to +105°C.
Technical Context
The OPA202IDBVR uses TI's precision super-beta complementary bipolar process to achieve ultra-low flicker noise and exceptional DC accuracy. Its input stage features matched PNP transistors enabling 2 nA max input bias current and 0.2 µVPP 0.1-Hz to 10-Hz noise - critical for low-frequency measurement integrity.
It avoids phase inversion under common-mode overdrive and maintains stability with heavy capacitive loads via internal compensation optimized for >5 µs settling time (to 0.1%) with 25 nF. The device supports rail-to-rail output swing within 750 mV of supply rails at no load and includes thermal, short-circuit, and EMI protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | ±200 µV max - ensures <0.2 mV error in 10 V full-scale systems without trimming |
| Drift | ±1 µV/°C max - limits temperature-induced error to <100 µV over 100°C ambient shift |
| Input Noise | 9 nV/√Hz @ 1 kHz - enables sub-µV resolution in bandwidth-limited precision DAQ |
| GBW | 1 MHz - supports stable unity-gain buffering of signals up to ~100 kHz |
| IQ per Amp | 580 µA typical - allows dual-channel operation below 1.2 mA total supply current |
| Cap Load Drive | 25 nF - eliminates need for external isolation resistors when driving ADC input caps or long cables |
| CMRR / PSRR | 126 dB min - rejects >2 million-fold common-mode or supply ripple interference |
Pinout & Package
OPA202IDBVR is housed in a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts and automated assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182IDBVR | Lower 5.7 nV/√Hz noise, zero-drift architecture, but higher 530 µA IQ; requires external charge pump for rail-to-rail input | Better for ultra-low-drift DC applications; less suitable for high-CL drive due to lower output current | Select OPA2182IDBVR only if sub-100 nV offset drift over temperature is mandatory and capacitive load <1 nF |
| AD8628ARJZ-R7 | Zero-drift, 0.1 µV max offset, but 1.5 µV/°C max drift and limited 10 nF CL drive; 1.2 mA IQ | Preferred for microvolt-level DC stability; not recommended for direct 25 nF ADC input driving | Choose AD8628ARJZ-R7 when absolute initial offset dominates system error budget and thermal drift is managed externally |
Compared with OPA202IDBVR, OPA2182IDBVR offers superior long-term DC stability but sacrifices capacitive drive strength and adds complexity, while AD8628ARJZ-R7 provides lower initial offset at the cost of higher quiescent current and reduced load-driving capability - making OPA202IDBVR the optimal balance for high-accuracy, high-CL, low-power applications.

FAQ
What is the maximum capacitive load the OPA202IDBVR can drive stably?
The OPA202IDBVR is specified to drive up to 25 nF capacitive loads stably, with 5-µs settling time to 0.1% for a 10-V step. This capability eliminates the need for external isolation resistors in ADC driver and cable-driving applications, simplifying design and improving signal fidelity. The OPA202IDBVR achieves this through internal compensation optimized for heavy load conditions.
Does the OPA202IDBVR exhibit phase reversal under input overvoltage?
No, the OPA202IDBVR does not exhibit phase reversal. Its input stage is designed to prevent output polarity inversion even when input signals exceed the supply rails - a critical reliability feature in systems exposed to transient overvoltages. This behavior is explicitly confirmed in the datasheet's Figure 29 ("No Phase Reversal") and enhances robustness in field-deployed instrumentation using OPA202IDBVR.
What is the input voltage noise density of the OPA202IDBVR at 1 kHz?
The OPA202IDBVR has an input voltage noise density of 9 nV/√Hz at 1 kHz, as specified in the Electrical Characteristics table (Section 6.7). This value is representative of its broadband noise performance and contributes to its suitability for precision, medium-bandwidth applications such as sensor signal conditioning and high-resolution data acquisition where OPA202IDBVR is commonly deployed.
Can the OPA202IDBVR operate from a single 5-V supply?
Yes, the OPA202IDBVR supports single-supply operation from 4.5 V to 36 V, including standard 5-V rails. Its input common-mode range extends to within 1.5 V of each rail, and output swings to within 750 mV of the rails under no load - enabling effective use in 5-V systems with appropriate level-shifting or reference design. This flexibility is confirmed in Section 6.3 (Recommended Operating Conditions) of the OPA202IDBVR datasheet.
How does the OPA202IDBVR compare to legacy precision op-amps like OP-07?
The OPA202IDBVR is positioned as a modern replacement for OP-07 and OP-27, offering significantly lower quiescent current (580 µA vs. ~2 mA), wider supply range (±2.25 V to ±18 V vs. ±3 V to ±18 V), superior 0.1–10 Hz noise (0.2 µVPP vs. ~0.6 µVPP), and built-in EMI hardening. Unlike OP-07, OPA202IDBVR drives 25 nF loads directly and operates reliably across –40°C to +105°C without performance degradation.
