Product details
Overview
TLC2262AIDRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for precision, low-noise, single- or split-supply operation. It delivers 950 µV max input offset voltage at 25°C, 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, 500 µA max supply current per amplifier, and full rail-to-rail output swing - enabling high-fidelity signal conditioning in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLC2262AIDRG4 datasheet, TLC2262AIDRG4 pinout, TLC2262AIDRG4 application, or TLC2262AIDRG4 equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail output behavior, validated low-input-bias-current performance for high-impedance sources, and precise alternative part comparisons for industrial temperature-range op-amp upgrades.
Technical Context
The TLC2262AIDRG4 implements an Advanced LinCMOS™ process architecture with complementary input transistors enabling common-mode input voltage range extending to the negative rail and rail-to-rail output swing. Its internal design achieves ultra-low input bias current (1 pA typ) while maintaining 0.55 V/µs slew rate and 0.73 MHz gain-bandwidth product under ±5 V supply conditions.
This device bridges micropower and ac performance: it draws less than 500 µA per amplifier yet supports 20 kHz THD+N < 0.014% and 14.1 µs settling time to 0.01% for ±2.3 V steps - making it suitable for precision analog front-ends where both DC accuracy and dynamic response matter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 950 µV max at TA = 25°C - ensures ≤1 LSB error when driving 12-bit ADCs with 5 V reference. |
| Input Bias Current | 1 pA typical - preserves signal integrity from >1 GΩ sources like piezoelectric sensors or pH electrodes. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - enables clean amplification of µV-level biopotential or strain-gauge signals. |
| Supply Current | 500 µA max per amplifier - supports multi-channel, battery-operated instrumentation with >1-year runtime. |
| Output Swing | Rail-to-rail (VDD– to VDD+) - maximizes dynamic range into SAR or sigma-delta ADCs without level-shifting. |
| Common-Mode Input Range | Includes VDD– - allows direct sensing of ground-referenced signals in single-supply systems. |
| Gain-Bandwidth Product | 0.73 MHz - supports stable unity-gain buffering and closed-loop gains up to ~10 for anti-alias filtering. |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel (R suffix), rated for –40°C to 125°C operating temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | High-impedance node accepting feedback or differential input; referenced to VDD–/GND. |
| 2 | Non-Inverting Input (Amplifier 1) | High-Z input for reference or sensor signal; common-mode range includes VDD–. |
| 3 | Output (Amplifier 1) | Rail-to-rail output capable of sourcing/sinking ±50 mA; drives ADC inputs directly. |
| 4 | VDD– / GND | Negative supply or ground reference; common return for both amplifiers and input common-mode range. |
| 5 | Non-Inverting Input (Amplifier 2) | Independent high-Z input; identical specs to Pin 2 - enables dual-channel signal conditioning. |
| 6 | Inverting Input (Amplifier 2) | Independent feedback node; supports separate gain configurations per channel. |
| 7 | Output (Amplifier 2) | Second rail-to-rail output; electrically isolated from Amp 1 except shared supply pins. |
| 8 | VDD+ | Positive supply rail (±2.2 V to ±8 V); powers both amplifiers; decoupling required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full VDD– to VDD+ output voltage range - eliminates need for level-shifting before ADC sampling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher slew rate (1.5 V/µs), wider supply range (2.7–6 V), but higher input offset (1.5 mV max) and noise (28 nV/√Hz). | Better for higher-speed active filters; less suitable for µV-level DC-critical measurements. | Select TLV2432IDR when bandwidth >1 MHz and supply is strictly 3.3 V; retain TLC2262AIDRG4 for low-noise, low-VIO precision. |
| OPA2333AIDR | Zero-drift architecture, 12 µV max VIO, lower noise (5.5 nV/√Hz), but higher quiescent current (17 µA per amp) and cost. | Required for sub-µV drift over temperature; overkill for static sensor offsets compensated in firmware. | Choose OPA2333AIDR only if <0.1 µV/°C drift is mandatory; TLC2262AIDRG4 offers optimal balance of VIO, noise, and power for most industrial designs. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262AIDRG4 uniquely combines 950 µV VIO, 12 nV/√Hz noise, and 500 µA supply current in an extended-temperature SOIC-8 - making it the most cost-effective precision dual op-amp for battery-constrained, wide-temperature industrial signal chains.

FAQ
What is the maximum operating temperature range for the TLC2262AIDRG4?
The TLC2262AIDRG4 is specified for operation from –40°C to 125°C, as indicated by the "I" temperature grade suffix and confirmed in the Absolute Maximum Ratings table. This extended range supports deployment in under-hood automotive modules, industrial motor drives, and outdoor environmental monitoring systems where ambient temperatures exceed standard commercial limits.
Does the TLC2262AIDRG4 support true rail-to-rail input capability?
No - the TLC2262AIDRG4 features rail-to-rail *output* swing but its common-mode input voltage range extends only to the negative rail (VDD–), not the positive rail. At ±5 V supply, VICR is –5 V to +3.5 V; at 5 V single supply, it is 0 V to +3.5 V. This allows ground-referenced inputs but requires input signals to remain ≥1.5 V below VDD+.
Can the TLC2262AIDRG4 drive a 10 kΩ load while maintaining rail-to-rail output?
Yes - the TLC2262AIDRG4 guarantees rail-to-rail output swing into loads ≥10 kΩ across its full operating temperature range. Electrical characteristics tables confirm VOH ≥4.82 V and VOL ≤0.15 V at VDD = 5 V with 500 µA load current, corresponding to effective output impedance <300 Ω - well within capability for 10 kΩ loads.
How does the input offset voltage of TLC2262AIDRG4 compare to the standard TLC2262IDRG4?
The "A" suffix in TLC2262AIDRG4 denotes the precision grade with 950 µV max input offset voltage at 25°C, versus 2.5 mV max for the standard TLC2262IDRG4. Both share the same SOIC-8 package and temperature range (–40°C to 125°C), but the "A" variant is binned for tighter VIO - critical for high-resolution data acquisition without system-level trimming.
Is the TLC2262AIDRG4 pin-compatible with legacy TS27M2 or TLC27M2 op-amps?
Yes - the TLC2262AIDRG4 uses the same SOIC-8 pinout as TS27M2 and TLC27M2, enabling drop-in replacement in existing designs. It improves upon those predecessors with rail-to-rail output, lower noise (12 nV/√Hz vs. ~25 nV/√Hz), lower input offset (950 µV vs. 2 mV), and lower input bias current (1 pA vs. 10 pA), delivering immediate performance uplift without PCB changes.
