Product details
Overview
OPA2210ID from Texas Instruments is a dual-channel, precision, low-noise, rail-to-rail output operational amplifier built on super-beta bipolar process. It delivers 2.2 nV/√Hz voltage noise density at 1 kHz, 5 µV typical offset voltage, 0.1 µV/°C typical drift, and 18 MHz gain bandwidth - enabling high-fidelity signal conditioning in medical instrumentation and high-resolution data acquisition systems.
For engineers reviewing the OPA2210ID datasheet, OPA2210ID pinout, OPA2210ID application, or OPA2210ID equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-amplifier topology, rail-to-rail output swing, ±2.25 V to ±18 V supply operation, and real-world settling time (2.6 µs to 16-bit accuracy) - all critical for precision analog front-end design.
Technical Context
The OPA2210ID implements a complementary bipolar super-beta input stage that achieves ultra-low 1/f noise corner and sub-0.5 µV/°C max drift while maintaining 132 dB minimum CMRR and 126 dB open-loop gain. Its unity-gain stable architecture supports fast settling without external compensation.
It features internal phase-reversal protection, no input clamping diodes that cause current injection, and robust ESD tolerance (±4 kV HBM). The device operates across –40°C to +125°C with guaranteed performance over full supply range (±2.25 V to ±18 V) and rail-to-rail output swing into 10 kΩ loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 2.2 nV/√Hz at 1 kHz - enables high-SNR amplification of low-level sensor signals below 1 µV |
| Offset Voltage | ±5 µV typical - reduces DC error in precision gain stages and reference buffers |
| Offset Drift | ±0.1 µV/°C typical - ensures stable calibration over industrial temperature range without recalibration |
| Gain Bandwidth | 18 MHz - supports >1 MSPS sampling in 16-bit SAR ADC driver applications |
| Slew Rate | 6.4 V/µs - allows clean 10-V output steps with <2.6 µs settling to 16-bit accuracy |
| Supply Range | ±2.25 V to ±18 V (or 4.5 V to 36 V single-supply) - compatible with legacy ±15 V and modern wide-range PSU designs |
| Quiescent Current | 2.5 mA per channel max - balances ultra-low noise with power efficiency in battery-aware precision systems |
Pinout & Package
OPA2210ID is housed in an industry-standard SOIC-8 (D) package measuring 4.90 mm × 3.91 mm, optimized for thermal performance (RθJA = 126.1°C/W) and board-level manufacturability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Output of amplifier channel A - rail-to-rail capable, drives 10 kΩ load to within 200 mV of rails |
| 2 | –IN A | Inverting input of channel A - super-beta bipolar input with 0.3 nA typical bias current |
| 3 | +IN A | Noninverting input of channel A - matched to –IN A for <5 µV offset and <0.1 µV/°C drift |
| 4 | V– | Negative supply pin - referenced to lowest system potential; supports dual or single-supply operation |
| 5 | +IN B | Noninverting input of channel B - electrically isolated from channel A; enables dual independent gain paths |
| 6 | –IN B | Inverting input of channel B - identical input characteristics as channel A for matched dual-channel performance |
| 7 | OUT B | Output of amplifier channel B - independently buffered, no crosstalk beyond specified 0.1 µV/V channel separation |
| 8 | V+ | Positive supply pin - accepts up to +18 V; supplies both channels simultaneously with shared PSRR >132 dB |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives to within 200 mV of either rail under 10 kΩ load - maximizes dynamic range in 3.3 V or ±15 V systems |
| No phase reversal | Internal protection prevents output inversion when inputs exceed common-mode range - eliminates latch-up risk in noninverting configurations |
| Ultra-low 0.1–10 Hz noise | 90 nVPP - critical for DC-coupled medical sensors (ECG, EEG) where baseline stability dominates SNR |
| High CMRR & PSRR | 132 dB min CMRR / 132 dB min PSRR - rejects interference from noisy digital supplies and shared ground returns |
| Wide temperature specification | Guaranteed performance from –40°C to +125°C - qualified for automotive cabin and industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2189ID | Lower 1/f noise (0.1 µVPP), higher quiescent current (1.3 mA/channel), same SOIC-8 package | Better for ultra-low-frequency (<1 Hz) biosensing; less suitable for wideband applications due to 10 MHz GBW | Select OPA2189ID when sub-Hz noise dominates; choose OPA2210ID for balanced noise-bandwidth-power trade-off |
| ADA4625-2ARZ | FET input (1 fA bias), higher voltage noise (4.2 nV/√Hz), wider supply (±5 V to ±18 V), same 8-pin SOIC | Preferred for picoampere-level photodiode or high-Z sensor interfaces; not optimal for low-voltage-noise requirements | Choose ADA4625-2ARZ for femtoampere input leakage; retain OPA2210ID when voltage noise <2.5 nV/√Hz is mandatory |
Compared with OPA2189ID and ADA4625-2ARZ, the OPA2210ID uniquely combines bipolar-input precision (5 µV offset, 0.1 µV/°C drift) with ultra-low voltage noise (2.2 nV/√Hz) and 18 MHz bandwidth - making it the only option among the three qualified for simultaneous high-resolution DC accuracy and wideband fidelity in medical and test equipment.

FAQ
What is the maximum supply voltage rating for the OPA2210ID?
The OPA2210ID has an absolute maximum supply voltage of ±20 V (40 V total), but its recommended operating range is ±2.25 V to ±18 V. Operation beyond ±18 V risks permanent damage and invalidates parametric guarantees. The OPA2210ID's internal protection circuitry does not extend safe operation beyond these limits, and TI explicitly cautions against exceeding 40 V total supply differential.
Does the OPA2210ID support single-supply operation?
Yes, the OPA2210ID supports true single-supply operation from 4.5 V to 36 V. Its rail-to-rail output stage and extended common-mode input range (V– + 1.5 V to V+ – 1.5 V) allow use in 5 V, 12 V, or 24 V systems without level-shifting. Input and output functionality remains fully specified across this range, including offset voltage and noise performance.
What is the settling time of the OPA2210ID to 16-bit accuracy?
The OPA2210ID settles to 16-bit accuracy (0.0015%) in 2.6 µs for a 10-V output step with G = –1 configuration and 100 pF capacitive load. This value is measured under standard conditions (VS = ±15 V, TA = 25°C, RL = 10 kΩ) and is guaranteed across the full industrial temperature range (–40°C to +125°C) per datasheet Section 6.6.
Is the OPA2210ID pin-compatible with the OPA210ID?
No, the OPA2210ID is not pin-compatible with the OPA210ID. While both use SOIC-8 packages, the OPA210ID is a single-channel amplifier (pinout: OUT, –IN, +IN, V–, NC, NC, V+, NC), whereas the OPA2210ID is dual-channel with dedicated pins for both amplifiers (OUT A, –IN A, +IN A, V–, +IN B, –IN B, OUT B, V+). PCB layout must be redesigned for channel count and pin assignment differences.
What thermal metrics apply to the OPA2210ID in SOIC-8 package?
For the OPA2210ID in SOIC-8 (D) package, the key thermal metrics are RθJA = 126.1°C/W (junction-to-ambient), RθJC(top) = 65.7°C/W (junction-to-case top), and RθJB = 69.5°C/W (junction-to-board). These values are measured per JEDEC JESD51 standards and reflect actual board-level thermal performance under defined test conditions.
