Product details
Overview
TLV2262AQD from Texas Instruments is a dual rail-to-rail output CMOS operational amplifier designed for low-voltage, low-power precision signal conditioning. It delivers 950 µV max input offset voltage, 12 nV/√Hz input voltage noise at 1 kHz, and 500 µA max supply current per amplifier across −40°C to 125°C. It operates from 2.7 V to 8 V and supports single- or split-supply configurations - ideal for interfacing with 3-V ADCs in automotive sensor front-ends.
For engineers reviewing the TLV2262AQD datasheet, TLV2262AQD pinout, TLV2262AQD application, or TLV2262AQD equivalent, key selection considerations include its guaranteed 950 µV VIO over full temperature range, rail-to-rail output swing, ultra-low 1 pA typical input bias current, and Q-temp automotive qualification for under-hood sensing and battery monitoring systems.
Technical Context
The TLV2262AQD implements a CMOS input stage with high-impedance differential pair and rail-to-rail output stage using complementary PMOS/NMOS drivers. Its architecture enables common-mode input voltage range extending to the negative rail and output swing within 100 mV of both supply rails at 500 µA supply current.
It is fully characterized at 3 V and 5 V, optimized for low-voltage operation in battery-powered and automotive applications. The device features internal ESD protection, macromodel support for SPICE simulation, and is qualified to AEC-Q100 Grade 1 (−40°C to 125°C) with configuration control and print support for high-reliability automotive programs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - supports direct integration into 3.3-V and 5-V automotive microcontroller domains without level-shifting. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C and full range - ensures <1 LSB error when driving 12-bit ADCs with 3-V reference. |
| Supply Current (max) | 500 µA per amplifier - enables dual-channel amplification in always-on vehicle subsystems with sub-1-mW total quiescent power. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - preserves signal integrity for piezoelectric transducer and thermopile sensor interfaces. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct sensing of ground-referenced signals without biasing networks. |
| Output Swing | Rail-to-rail - delivers full dynamic range to ADCs, maximizing SNR and effective resolution in low-voltage data acquisition. |
| Gain-Bandwidth Product | 0.67 MHz at VDD = 3 V - sufficient for anti-aliasing filtering and sensor signal buffering up to ~100 kHz. |
Pinout & Package
TLV2262AQD is supplied in an 8-pin SOIC (D) package with exposed pad option not specified. Pin mapping follows standard dual op-amp configuration with independent inputs and outputs per channel, plus shared power and ground terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Amplified output of first op-amp; rail-to-rail capable, drives ADC input or analog switch directly. |
| 2 | Channel 1 Inverting Input | Inverting node for feedback configuration; 10¹² Ω input resistance minimizes loading on high-Z sources. |
| 3 | Channel 1 Non-Inverting Input | High-impedance sensor interface point; accepts signals down to VDD− with no external bias required. |
| 4 | Ground / VDD− | Reference return for both amplifiers; connects to system ground or negative supply in split-rail mode. |
| 5 | VDD+ | Positive supply rail; accepts 2.7–8 V; decoupling capacitor required near pin for stability at high frequencies. |
| 6 | Channel 2 Output | Second independent rail-to-rail output; enables dual-sensor conditioning or differential drive capability. |
| 7 | Channel 2 Inverting Input | Independent inverting input; supports individual gain-setting resistors per channel without crosstalk. |
| 8 | Channel 2 Non-Inverting Input | Second high-Z input; allows simultaneous monitoring of two sensors (e.g., temperature + pressure) with matched DC specs. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2262AID | Same electrical specs but in industrial-grade −40°C to 125°C temp range; D-package, non-automotive qualified. | Lacks AEC-Q100 qualification and Q-Temp configuration control; not approved for automotive production. | Select TLV2262AID only for non-automotive industrial designs where cost sensitivity outweighs qualification requirements. |
| TLV2432CD | Higher output drive (±30 mA), wider input voltage range (VDD− to VDD+ −1.5 V), but higher 650 µA supply current and 1.5 mV VIO max. | Better suited for driving heavy capacitive loads or higher-voltage signal chains; less optimal for ultra-low-power precision sensing. | Choose TLV2432CD when output current >20 mA or input common-mode range beyond rail is required - not for battery-constrained automotive nodes. |
Compared with TLV2262AID, TLV2262AQD adds automotive qualification and traceable lot control; compared with TLV2432CD, it trades output drive for lower power and tighter DC accuracy - making TLV2262AQD the optimal choice for precision, low-quiescent automotive sensor interfaces.

FAQ
What is the maximum operating temperature range for TLV2262AQD?
The TLV2262AQD is rated for continuous operation from −40°C to 125°C, meeting AEC-Q100 Grade 1 requirements. This range is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and output swing - ensuring reliable performance in under-hood automotive environments and high-temperature industrial enclosures.
Does TLV2262AQD support true rail-to-rail input capability?
No, TLV2262AQD does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but stops 1.3 V below the positive rail (VDD+ −1.3 V) at 3 V supply. This design enables robust operation with high open-loop gain while maintaining low input bias current - appropriate for sensor buffering where the signal stays near ground.
Is TLV2262AQD pin-compatible with TLV2262CD or TLV2262AID?
Yes, TLV2262AQD shares identical 8-pin SOIC (D) package and pinout with TLV2262CD and TLV2262AID. All three devices use the same pin mapping: pins 1–3 and 6–8 for Channel 1 and Channel 2 I/O, pin 4 for VDD−/GND, and pin 5 for VDD+. However, TLV2262AQD's automotive qualification and tighter VIO spec require validation in safety-critical designs even with mechanical compatibility.
What is the typical input bias current of TLV2262AQD and why does it matter?
The typical input bias current of TLV2262AQD is 1 pA at 25°C, rising to 150 pA at 85°C. This ultra-low value prevents loading errors in high-impedance sensor circuits - such as thermocouples, piezoelectric elements, or pH electrodes - where even nanoamp-level currents would induce significant offset voltage across series impedances exceeding 1 MΩ.
Can TLV2262AQD operate from a single 3.3-V supply?
Yes, TLV2262AQD is fully specified for single-supply operation from 2.7 V to 8 V, including 3.3 V. At 3.3 V, it delivers rail-to-rail output swing (within 100 mV of each rail), 950 µV max input offset voltage, and 500 µA max supply current - making it ideal for interfacing with 3.3-V microcontrollers and 12-bit ADCs in compact automotive modules.
