Product details
Overview
OPA4202IPW from Texas Instruments is a precision quad operational amplifier designed for high-accuracy signal conditioning in demanding analog systems. It delivers 200 µV maximum offset voltage, 1 µV/°C max drift, 9 nV/√Hz input voltage noise, and stable operation driving capacitive loads up to 25 nF - enabling direct interface with ADC drivers, sensor front-ends, and precision power supply monitors.
For engineers reviewing the OPA4202IPW datasheet, OPA4202IPW pinout, OPA4202IPW application, or OPA4202IPW equivalent, key selection criteria include its ±2.25 V to ±18 V dual-supply range, 1 MHz gain-bandwidth product, 580 µA per-amplifier quiescent current, and robust EMI hardening - all validated across –40°C to +105°C industrial temperature operation.
Technical Context
The OPA4202IPW employs TI's precision super-beta complementary bipolar process, delivering ultra-low flicker noise and exceptional linearity over common-mode and supply variations. Its architecture eliminates phase inversion and supports unity-gain stability with heavy capacitive loads (≥25 nF), enabled by internal compensation optimized for drive strength without external isolation resistors.
It features 3000 GΩ ultra-high input impedance and 0.5 pF input capacitance, minimizing loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance stages. CMRR and PSRR both exceed 126 dB (min), ensuring rejection of supply and common-mode disturbances in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | ±200 µV max - enables sub-0.1% accuracy in 12-bit+ measurement systems without trimming |
| Drift | ±1 µV/°C max - ensures <10 µV total drift over –40°C to +105°C, critical for uncalibrated field instruments |
| Gain-Bandwidth | 1 MHz - supports stable closed-loop gain ≥10 at 100 kHz for anti-aliasing filter buffering |
| Voltage Noise | 9 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouples, strain gauges) |
| Capacitive Load Drive | 25 nF - allows direct connection to long PCB traces, multiplexer outputs, or ADC input capacitors without instability |
| Supply Range | ±2.25 V to ±18 V - accommodates both low-voltage portable DAQ and high-voltage industrial control rails |
| Quiescent Current | 580 µA per amplifier - enables four-channel precision amplification within 2.3 mA total, suitable for battery-backed modules |
Pinout & Package
OPA4202IPW is housed in a 14-pin TSSOP (PW) package measuring 5.00 mm × 4.40 mm, optimized for high-density industrial PCB layouts while maintaining thermal performance (RθJA = 116.6°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output A–D | Low-impedance buffered outputs capable of sourcing/sinking ±35 mA; rail-to-rail swing limited to 750 mV from supply rails |
| 2, 6, 9, 13 | Inverting Input A–D | Differential inputs with 3000 GΩ impedance; internally diode-clamped ±0.5 V beyond rails for ESD protection |
| 3, 5, 10, 12 | Noninverting Input A–D | Matched to inverting inputs; differential clamping prevents latch-up during overvoltage transients |
| 4 | V+ | Positive supply terminal - must be decoupled locally with ≥0.1 µF ceramic capacitor to ground |
| 11 | V− | Negative supply terminal - shared return for all four amplifiers; requires low-impedance path to minimize crosstalk |
Key Features
| Feature | Design Value |
|---|---|
| Heavy capacitive load drive | Stable with ≥25 nF loads and 5-µs settling time to 0.1%, eliminating need for output isolation resistors in ADC driver designs |
| EMI hardening | Integrated filtering rejects >60 dB of RF interference up to 1 GHz (EMIRR IN+ = 40 dB @ 900 MHz), critical for medical and telecom equipment |
| Ultra-low 0.1–10 Hz noise | 0.2 µVPP - minimizes baseline wander in DC-coupled biosignal acquisition (e.g., ECG, EEG front-ends) |
| No phase inversion | Guaranteed linear behavior beyond input common-mode range (VCM = V− + 1.5 V to V+ − 1.5 V), preventing catastrophic output reversal in overdrive conditions |
| Thermal & short-circuit protection | Internal foldback limits dissipation during sustained overload, enabling reliable operation in unattended industrial controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4182IPW | Lower offset (±4 µV), higher GBW (10 MHz), but higher IQ (500 µA per amp) and no EMI hardening | Better for high-speed precision (<100 kHz) but unsuitable in RF-noisy server racks or medical enclosures | Select when bandwidth >2 MHz is required and EMI immunity is secondary |
| AD8628ARUZ-REEL | Zero-drift architecture (0.005 µV/°C), lower noise (5.5 nV/√Hz), but limited capacitive drive (<100 pF) and no thermal protection | Ideal for ultra-stable DC references but cannot drive ADC inputs or multiplexers directly | Select only for pure DC/low-frequency (<10 kHz) applications with minimal layout constraints |
Compared with OPA4202IPW, OPA4182IPW trades EMI resilience and capacitive drive for speed and initial accuracy, while AD8628ARUZ-REEL sacrifices drive capability and ruggedness for near-zero drift - making OPA4202IPW the optimal balance for industrial DAQ and medical sensor interfaces requiring robustness and wide supply flexibility.

FAQ
What is the maximum capacitive load the OPA4202IPW can drive without oscillation?
The OPA4202IPW is specified to remain stable driving up to 25 nF capacitive loads with 5-µs settling time to 0.1%. This capability is verified across –40°C to +105°C and eliminates the need for series isolation resistors in ADC driver or multiplexer interface applications. The OPA4202IPW achieves this via internal compensation optimized for heavy load drive, unlike standard precision op-amps that require external stabilization.
Does the OPA4202IPW support single-supply operation?
Yes, the OPA4202IPW supports single-supply operation from 4.5 V to 36 V, in addition to dual-supply ranges 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 the rails under no-load conditions - enabling use in 5 V, 12 V, or 24 V industrial systems without level-shifting circuitry.
How does the EMI hardening in the OPA4202IPW improve system reliability?
The OPA4202IPW integrates on-chip RF filters on both inputs, achieving >40 dB EMIRR (Electromagnetic Interference Rejection Ratio) at 900 MHz. This prevents GSM, Wi-Fi, and switching power supply noise from modulating the input stage and inducing erroneous offsets or distortion - a critical feature validated in EN 61000-4-3 radiated immunity testing for medical and telecom equipment where OPA4202IPW is deployed.
What is the typical quiescent current per amplifier in the OPA4202IPW?
The OPA4202IPW draws 580 µA per amplifier at ±18 V, totaling 2.32 mA for all four channels. This value remains stable across supply voltages from ±2.25 V to ±18 V and varies only ±10% over –40°C to +105°C, enabling predictable power budgeting in thermally constrained enclosures or battery-powered portable instruments using the OPA4202IPW.
Can the OPA4202IPW replace legacy OP-07 or OP-27 op-amps in existing designs?
Yes, the OPA4202IPW is explicitly positioned as a drop-in replacement for OP-07 and OP-27 in quad configurations, offering superior specs: lower offset (200 µV vs. 60 µV typical for OP-27 but with guaranteed max), lower drift (1 µV/°C vs. 0.6 µV/°C typical), and added features including EMI hardening, thermal protection, and 25 nF capacitive drive - all in pin-compatible TSSOP-14 packaging with identical footprint to legacy SOIC-14 variants.
