Product details
Overview
OPA4202ID from Texas Instruments is a precision quad operational amplifier built on super-beta bipolar process, delivering 200 µV max offset voltage, 1 µV/°C max drift, 9 nV/√Hz input voltage noise, and stable operation driving up to 25 nF capacitive loads - used in high-accuracy data acquisition front-ends and medical patient monitor signal conditioning stages.
For engineers reviewing the OPA4202ID datasheet, OPA4202ID pinout, OPA4202ID application, or OPA4202ID equivalent, key selection considerations include its ±2.25 V to ±18 V dual-supply range, 1 MHz gain-bandwidth, 580 µA quiescent current per amplifier, heavy capacitive load drive capability, and EMI-hardened architecture for lab instrumentation and industrial sensing environments.
Technical Context
The OPA4202ID employs complementary bipolar super-beta technology to achieve ultra-low flicker noise and exceptional DC precision while maintaining robustness against EMI, thermal stress, and short-circuit events. Its input stage features 3000 GΩ input impedance and 0.5 pF input capacitance, enabling high-impedance sensor interfacing without phase inversion.
It operates stably with capacitive loads up to 25 nF (5-µs settling time), supports rail-to-rail output swing within 750 mV of supply rails at ±18 V, and maintains ≥126 dB CMRR and PSRR across –40°C to +105°C - critical for multiparameter patient monitors and string inverter voltage sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | ±200 µV max - ensures <0.01% error in 20 V full-scale precision measurement systems |
| Drift | ±1 µV/°C max - enables stable calibration over industrial temperature range without frequent recalibration |
| Input Voltage Noise | 9 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, strain gauge) |
| Gain-Bandwidth | 1 MHz - supports unity-gain stable signal conditioning for DC–100 kHz sensor bandwidths |
| Quiescent Current | 580 µA per amplifier - allows four-channel precision amplification within 2.3 mA total supply budget |
| Capacitive Load Drive | 25 nF - eliminates need for isolation resistors when driving ADC input filters or long PCB traces |
| Supply Range | ±2.25 V to ±18 V - accommodates both low-voltage portable instruments and high-voltage industrial power supplies |
Pinout & Package
OPA4202ID is housed in a 14-pin SOIC package (8.65 mm × 3.91 mm) with standard quad op-amp pinout optimized for layout symmetry and thermal uniformity across channels.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier outputs - each capable of sourcing/sinking 35 mA and swinging within 750 mV of rails at ±18 V |
| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs - matched to +IN pins for precise differential gain configuration |
| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs - ultra-high 3000 GΩ impedance minimizes loading on high-Z sources |
| 4 | V+ | Positive supply terminal - accepts up to +18 V; decoupling required within 1 cm for EMI immunity |
| 11 | V– | Negative supply terminal - accepts down to –18 V; shared return path for all four amplifiers |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4182ID | Lower 5.6 nV/√Hz noise, higher 10 MHz GBW, but 1.3 mA IQ - less suitable for low-power multi-channel designs | Better for high-speed precision applications (e.g., active filters >100 kHz); not optimized for heavy capacitive drive | Choose OPA4182ID only if bandwidth >1 MHz and noise <6 nV/√Hz are mandatory; otherwise OPA4202ID offers superior cost/power/capacitive-load balance |
| AD8628ARZ-REEL | Zero-drift architecture (0.005 µV/°C), but 2.5 MHz GBW and limited 10 nF capacitive drive - no guaranteed stability beyond 10 nF | Ideal for ultra-stable DC offsets (e.g., weigh scales), but unsuitable for fast-settling sensor interfaces with large filters | Select AD8628ARZ-REEL only for sub-µV/°C drift-critical DC applications; OPA4202ID remains preferred where capacitive load drive and EMI immunity are primary requirements |
Compared with OPA4182ID and AD8628ARZ-REEL, the OPA4202ID uniquely balances ultra-low drift, low noise, and robust 25 nF capacitive load drive in a single quad package - making it the optimal choice for space-constrained, EMI-prone, multi-channel precision systems requiring both accuracy and stability.

FAQ
What is the maximum capacitive load the OPA4202ID can drive without instability?
The OPA4202ID is specified to drive up to 25 nF capacitive loads while maintaining stability and achieving 5-µs settling time to 0.1%. This capability eliminates the need for external isolation resistors in ADC input filter networks and simplifies layout in high-precision data acquisition systems using the OPA4202ID.
Does the OPA4202ID exhibit phase inversion when input common-mode voltage exceeds supply rails?
No, the OPA4202ID does not exhibit phase inversion under any condition - a key reliability feature confirmed in the datasheet's Figure 29. This behavior ensures predictable operation during power-up, fault conditions, or transient overvoltage events in systems using the OPA4202ID.
What is the input bias current specification for the OPA4202ID over temperature?
The OPA4202ID specifies ±2.1 nA maximum input bias current across the full –40°C to +105°C operating range. This low, tightly bounded bias current enables accurate amplification of high-impedance sensor signals without significant DC error accumulation in circuits using the OPA4202ID.
Can the OPA4202ID operate from a single 5-V supply?
Yes, the OPA4202ID supports single-supply operation from 4.5 V to 36 V. At 5 V, it delivers full functionality including 120 dB minimum open-loop gain and 114 dB minimum CMRR - making it viable for low-voltage portable instrumentation designs using the OPA4202ID.
How does the OPA4202ID compare to legacy precision op-amps like OP-07 and OP-27?
The OPA4202ID replaces OP-07 and OP-27 with superior performance: lower 200 µV max offset vs. 60 µV typical for OP-07, 1 µV/°C max drift vs. 0.6 µV/°C typical for OP-27, plus integrated EMI hardening and 25 nF capacitive load drive - all in a modern quad SOIC package compatible with the OPA4202ID footprint.
