Product details
Overview
TLV2262QD from Texas Instruments is a dual, rail-to-rail output CMOS operational amplifier optimized for automotive-grade low-voltage operation (2.7 V to 8 V). 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 - enabling precision signal conditioning in battery-powered sensor interfaces and ADC front-ends.
For engineers reviewing the TLV2262QD datasheet, TLV2262QD pinout, TLV2262QD application, or TLV2262QD equivalent, key selection criteria include its −40°C to 125°C automotive temperature range, rail-to-rail output swing, low input bias current (1 pA typ), and compatibility with single-supply 3 V/5 V systems in safety-critical analog sensing paths.
Technical Context
The TLV2262QD employs Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and low power consumption while maintaining stable unity-gain operation. Its fully differential input stage supports common-mode input voltage down to the negative rail, and its rail-to-rail output stage drives loads up to ±50 mA with <300 mV low-level output voltage at 1 mA sink current.
Designed for robustness in automotive environments, the device is qualified to AEC-Q100 standards and features internal ESD protection (>2 kV HBM). It operates reliably across full supply range (2.7 V–8 V) with specified performance at both 3 V and 5 V, supporting legacy 5 V and emerging ultra-low-power 3 V microcontroller-based systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct use with Li-ion, 3.3 V, and 5 V rails without regulation |
| Input Offset Voltage | 950 µV max at TA = 25°C - ensures ≤0.5% error in 2 V full-scale sensor outputs |
| Input Bias Current | 1 pA typical - preserves signal integrity from high-impedance sources like piezoelectric sensors |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–VDD input ranges |
| Supply Current | 500 µA max per amplifier - supports always-on monitoring with sub-1 mA total quiescent draw |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - critical for low-amplitude signal amplification in medical or industrial transducers |
| Gain-Bandwidth Product | 0.67 MHz at VDD = 3 V - sufficient for anti-aliasing filters and DC-coupled sensor buffers |
Pinout & Package
TLV2262QD is housed in an 8-pin SOIC (D) package with standard dual-op-amp pinout and no exposed pad. The package is RoHS-compliant and rated for −40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives ADC inputs or low-impedance loads directly |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance node; sensitive to PCB leakage and layout parasitics |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts signals referenced to GND or negative rail |
| 4 | GND / VDD− | Power return and negative supply reference - must be low-impedance connection to minimize PSRR degradation |
| 5 | VDD+ | Positive supply input - decoupling capacitor (0.1 µF) required within 1 cm for stability |
| 6 | OUT B | Amplifier B output - independent channel for differential pair or dual-sensor conditioning |
| 7 | IN− B | Inverting input of Amplifier B - electrically isolated from Channel A per datasheet layout guidelines |
| 8 | IN+ B | Non-inverting input of Amplifier B - supports independent gain configuration from Channel A |
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 Industrial temp range (−40°C to 125°C); D package identical; not AEC-Q100 qualified | Lacks automotive qualification - unsuitable for safety-critical ECU or ADAS subsystems | Select TLV2262AID only for non-automotive industrial equipment where AEC-Q100 is not mandated |
| OPA2333QDGKR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2262QD's 2 µV/°C; higher supply current (17 µA per amp) | Better DC precision over temperature; trades off power for offset stability in long-duration measurements | Choose OPA2333QDGKR when system-level offset drift dominates error budget, not quiescent power |
Compared with TLV2262AID, TLV2262QD provides automotive qualification and guaranteed performance over extended temperature extremes; compared with OPA2333QDGKR, it offers 30× lower quiescent current at the expense of higher offset drift - making TLV2262QD optimal for always-on, battery-constrained automotive sensing where moderate DC accuracy suffices.

FAQ
What is the operating temperature range for TLV2262QD?
The TLV2262QD is qualified for operation from −40°C to 125°C and meets AEC-Q100 Grade 2 requirements. This range is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and output drive capability - making TLV2262QD suitable for under-hood automotive applications and industrial environments with wide thermal excursions.
Does TLV2262QD support true rail-to-rail input?
No, TLV2262QD supports rail-to-rail *output* swing but has a common-mode input voltage range extending only to VDD− and up to VDD+ −1.3 V. At VDD = 3 V, this allows input signals from 0 V to 1.7 V; at VDD = 5 V, from 0 V to 3.7 V. The input stage does not accept signals at the positive rail, unlike some newer TI amplifiers such as the TLV9002.
What is the maximum output current capability of TLV2262QD?
TLV2262QD can source or sink up to ±50 mA per amplifier, as specified in Absolute Maximum Ratings. However, for linear operation with minimal distortion and thermal rise, the recommended continuous output current is ±20 mA. At ±10 mA load, output voltage swing remains within 100 mV of each rail at VDD = 3 V - sufficient for driving 10 kΩ ADC inputs or small FET gates.
Can TLV2262QD be used with a single 2.7 V supply?
Yes, TLV2262QD is fully characterized and guaranteed to operate from 2.7 V to 8 V. At 2.7 V, it maintains rail-to-rail output swing, 500 µA max supply current, and 950 µV max input offset voltage - enabling direct use with single-cell LiFePO₄ batteries or regulated 2.7 V LDO outputs in space-constrained automotive modules.
Is there a SPICE model available for TLV2262QD?
Yes, Texas Instruments provides a validated PSpice macromodel for the TLV2262 family, including TLV2262QD, on ti.com. The model accurately reproduces AC performance (gain-bandwidth, slew rate), noise behavior (voltage and current noise spectral density), and DC characteristics (input offset, bias current) across temperature and supply voltage - supporting pre-layout simulation of sensor interface circuits before prototyping.
