Texas Instruments TLV2264AQPWRQ1

Overview

TLV2264AQPWRQ1 from Texas Instruments is a quad rail-to-rail output operational amplifier designed for automotive-grade signal conditioning in low-voltage systems. It delivers 950 µV max input offset voltage, 12 nV/√Hz typical input voltage noise at 1 kHz, 500 µA max supply current per amplifier, and operates across 2.7 V to 8 V supply range. It is used in precision sensor interfaces and ADC driver stages within engine control units and battery management systems.

For engineers reviewing the TLV2264AQPWRQ1 datasheet, TLV2264AQPWRQ1 pinout, TLV2264AQPWRQ1 application, or TLV2264AQPWRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, rail-to-rail output swing, low 1 pA typical input bias current, wide common-mode input range extending to the negative rail, and guaranteed performance from –40°C to 125°C.

Technical Context

The TLV2264AQPWRQ1 implements a CMOS-based Advanced LinCMOS™ architecture optimized for low-voltage operation (2.7 V–8 V) with rail-to-rail output stage enabling full dynamic range utilization in single-supply configurations. Its input stage features high-impedance p-channel differential pairs delivering 10¹² Ω common-mode and differential input resistance.

It supports both single- and split-supply operation with common-mode input voltage range from VDD– to (VDD+ – 1.3 V), and exhibits stable unity-gain performance with 55° phase margin into 50 kΩ//100 pF loads - critical for driving SAR ADC inputs without settling errors.

FAQ

What is the maximum operating temperature for TLV2264AQPWRQ1?

The TLV2264AQPWRQ1 is rated for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements for automotive under-hood applications. This specification is validated across process corners and voltage extremes, and thermal derating follows the PW-14 package dissipation curve: 700 mW at 25°C, linearly reduced to 140 mW at 125°C. TLV2264AQPWRQ1 must be mounted on PCBs with adequate copper pour and thermal vias to maintain junction temperature within limits.

Does TLV2264AQPWRQ1 support single-supply operation?

Yes, TLV2264AQPWRQ1 fully supports single-supply operation from 2.7 V to 8 V. Its input common-mode range extends to the negative rail (VDD–), and output swings rail-to-rail - enabling direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without level-shifting circuitry. The device is characterized across this range at both 3 V and 5 V, with all key parameters including VIO, CMRR, and PSRR guaranteed over the full supply and temperature range.

What is the input bias current specification for TLV2264AQPWRQ1?

The TLV2264AQPWRQ1 has a typical input bias current of 1 pA at 25°C and a maximum of 60 pA across the full –40°C to 125°C temperature range. This ultra-low value results from its p-channel CMOS input stage and enables accurate amplification of high-impedance sources such as thermistors, photodiodes, and pH electrodes without introducing significant offset or drift. Input bias current remains stable over supply voltage and common-mode voltage variations.

Is TLV2264AQPWRQ1 pin-compatible with other quad op-amps in TSSOP-14?

No, TLV2264AQPWRQ1 uses a proprietary pinout optimized for layout symmetry and noise isolation between channels - it is not pin-compatible with generic quad op-amps like LM324 or TLV2374. The pin mapping places VDD+ and GND centrally to minimize supply coupling, and separates inverting/non-inverting inputs across quadrants. Migration requires PCB redesign; however, functional equivalents like LMV324QDRQ1 offer different pinouts but similar application coverage.

How does TLV2264AQPWRQ1 handle capacitive loads?

TLV2264AQPWRQ1 is stable for capacitive loads up to 100 pF with 50 kΩ series resistance, achieving 55° phase margin at unity gain. For larger loads (e.g., ADC input capacitance >100 pF), a 20 Ω to 50 Ω isolation resistor is recommended between TLV2264AQPWRQ1 output and the load. The device's internal compensation avoids need for external compensation networks, simplifying design in space-constrained automotive modules while maintaining <12.5 µs 0.01% settling time to 2 V step.
