Product details
Overview
TLC2262AQD from Texas Instruments is a dual rail-to-rail output operational amplifier designed for precision, low-noise signal conditioning in automotive and industrial systems. It delivers 950 µV max input offset voltage at 25°C, 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current per amplifier, and operates from ±2.2 V to ±8 V supplies across –40°C to 125°C. It is used in sensor front-ends interfacing with 12-bit ADCs in engine control units.
For engineers reviewing the TLC2262AQD datasheet, TLC2262AQD pinout, TLC2262AQD application, or TLC2262AQD equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail output swing, validated input bias current (1 pA typ), and direct alternative comparisons for automotive-grade op-amp selection.
Technical Context
The TLC2262AQD uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining high input impedance (>10¹² Ω) and ultra-low input bias current (1 pA typ). Its architecture supports both single-supply (e.g., 5 V) and split-supply (±5 V) operation with common-mode input range extending to the negative rail.
It features a gain-bandwidth product of 0.71 MHz (at 5 V), slew rate of 0.55 V/µs (typ), and phase margin of 56° - enabling stable unity-gain buffer and closed-loop configurations without external compensation. The device includes ESD protection and is qualified to AEC-Q100 Grade 1 standards for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 950 µV max at TA = 25°C - enables accurate DC-coupled amplification in precision sensor interfaces without trimming. |
| Supply Current | 500 µA max per amplifier - supports battery-powered or thermally constrained automotive modules. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - critical for low-level piezoelectric or strain gauge signal conditioning. |
| Rail-to-Rail Output | Swing within 10 mV of both rails at 100 µA load - maximizes dynamic range when driving SAR ADCs directly. |
| Common-Mode Input Range | Includes negative rail (VDD–) - allows ground-referenced single-supply designs without level-shifting circuitry. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive applications per AEC-Q100. |
| Gain-Bandwidth Product | 0.71 MHz - sufficient for anti-aliasing filters and low-frequency sensor signal chains up to ~100 kHz. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, tape-and-reel compatible. Pin 1 marked by beveled corner or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | High-impedance node accepting feedback or signal source; requires guarding in high-Z layouts. |
| 2 | Non-Inverting Input (Amplifier 1) | Accepts reference or sensor signal; common-mode range extends to VDD–. |
| 3 | Output (Amplifier 1) | Rail-to-rail capable output; drives loads down to 50 kΩ without significant swing loss. |
| 4 | VDD– / GND | Negative supply or ground reference; must be low-impedance for noise immunity. |
| 5 | VDD+ | Positive supply; decoupling capacitor (0.1 µF) required adjacent to pin. |
| 6 | Inverting Input (Amplifier 2) | Independent second channel input; matches Channel 1 performance and layout rules. |
| 7 | Non-Inverting Input (Amplifier 2) | Second channel positive input; isolated routing recommended to prevent crosstalk. |
| 8 | Output (Amplifier 2) | Second rail-to-rail output; usable for differential drive or independent signal paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full supply utilization - eliminates need for level-shifting before 12-bit ADCs. |
| Ultra-low input bias current | 1 pA typical - preserves signal integrity in high-impedance pH, piezo, or photodiode front-ends. |
| Low input voltage noise | 12 nV/√Hz at 1 kHz - reduces integrated noise in bandwidth-limited sensor amplifiers. |
| Automotive temperature grade | –40°C to +125°C operation with AEC-Q100 qualification - suitable for engine bay and transmission control. |
| Single- and split-supply support | Operates from 4.4 V to 16 V (single) or ±2.2 V to ±8 V (split) - simplifies power architecture reuse. |

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), lower GBW (2.2 MHz), 600 µA supply current, same SOIC-8 package. | Better for higher-frequency control loops (e.g., EPS motor current sensing), but higher noise (21 nV/√Hz). | Select TLV2432IDR when bandwidth >1 MHz is required and noise tolerance permits. |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, 0.65 µVpp 0.1–10 Hz noise, 55 µA supply current, SOIC-8. | Superior DC accuracy and long-term stability for ultra-precision applications (e.g., battery monitoring), but limited output drive. | Select OPA2333AIDR when sub-µV offset and near-zero drift outweigh rail-to-rail output and drive capability needs. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2262AQD offers the optimal balance of rail-to-rail output drive, low 12 nV/√Hz noise, and AEC-Q100 qualification - making it uniquely suited for cost-sensitive, thermally demanding automotive analog front-ends where moderate bandwidth suffices.

FAQ
What is the maximum operating supply voltage for the TLC2262AQD?
The TLC2262AQD supports a maximum supply voltage of ±8 V in split-supply mode or 16 V in single-supply mode. Absolute maximum ratings specify VDD+ ≤ 8 V and VDD– ≥ –8 V relative to midpoint; exceeding these risks permanent damage. Recommended operation remains within ±2.2 V to ±8 V for guaranteed parametric performance across –40°C to +125°C.
Does the TLC2262AQD support true rail-to-rail input operation?
No - the TLC2262AQD features rail-to-rail *output* swing only. Its common-mode input voltage range extends to the negative rail (VDD–) but stops 1.5 V below the positive rail (VDD+ – 1.5 V) under specified conditions. This allows ground-referenced single-supply use but requires input signals to remain within that limited VICR window.
Is the TLC2262AQD pin-compatible with the standard TLC2262CD or TLC2262ID variants?
Yes - all TLC2262x variants in the SOIC-8 (D) package share identical pinout and footprint, including TLC2262AQD, TLC2262CD, and TLC2262ID. Differences lie solely in temperature grading, input offset voltage specification (950 µV max for 'A' grade), and automotive qualification - not physical layout.
What is the typical input bias current of the TLC2262AQD, and why does it matter in sensor applications?
The TLC2262AQD has a typical input bias current of 1 pA at 25°C. This ultra-low value prevents loading of high-impedance sources such as piezoelectric accelerometers, pH electrodes, or NTC thermistors with series resistances >1 MΩ - preserving signal fidelity and minimizing offset errors caused by IR drops across source impedances.
Can the TLC2262AQD drive a 100-kΩ load while maintaining rail-to-rail output swing?
Yes - the TLC2262AQD maintains rail-to-rail output swing (within 10 mV of each rail) when sourcing or sinking up to ±100 µA. At 100-kΩ load (±50 µA), it achieves VOH ≥ 4.94 V and VOL ≤ 0.01 V on a 5-V supply - fully compliant with rail-to-rail specification and suitable for direct interface with 12-bit ADCs requiring full-scale utilization.
