Product details
Overview
TLV2264AQDG4 from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, low-power precision signal conditioning in automotive applications. It delivers 950 µV max input offset voltage at 25°C, 12 nV/√Hz input voltage noise at 1 kHz, and 500 µA max supply current per amplifier across −40°C to 125°C. Its 2.7 V to 8 V supply range and rail-to-rail output swing make it suitable for interfacing with 3-V ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLV2264AQDG4 datasheet, TLV2264AQDG4 pinout, TLV2264AQDG4 application, or TLV2264AQDG4 equivalent, key selection criteria include guaranteed A-grade offset performance over automotive temperature range, CMOS input bias current ≤1 pA typ, and validated Q-temp qualification per AEC-Q100 for high-reliability vehicle systems.
Technical Context
The TLV2264AQDG4 implements a CMOS-input, rail-to-rail output op-amp architecture with fully differential input stage and Class AB output buffer. It operates across 2.7 V–8 V supplies and supports common-mode input voltage down to the negative rail (VDD−), enabling single-supply operation with ground-referenced sensors.
Its 0.67 MHz gain-bandwidth product and 0.35 V/µs typical slew rate are optimized for DC-coupled precision amplification-not high-speed signal processing-while maintaining low 1 pA typical input bias current and 10¹² Ω input resistance for high-impedance source interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - Enables direct use with 3.3 V and 5 V automotive subsystems without level-shifting. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - Ensures <1 mV DC error in precision sensor gain stages without trimming. |
| Input Bias Current (typ) | 1 pA - Preserves signal integrity when amplifying outputs from piezoelectric or pH sensors. |
| Supply Current (per amp) | 500 µA max - Supports four-channel operation at ≤2 mA total, critical for always-on vehicle modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2264AIDR | Same electrical specs but in tape-and-reel SOIC-14; not Q-temp qualified; rated −40°C to 125°C industrial grade. | Lacks AEC-Q100 certification and configuration control; unsuitable for safety-critical automotive functions. | Select TLV2264AIDR only for non-automotive industrial designs where cost is prioritized over automotive compliance. |
| LMV324QDRQ1 | Lower offset (1.8 mV max), higher supply current (120 µA/amp), rail-to-rail input/output, AEC-Q100 qualified. | Better input rail-to-rail range but higher noise (29 nV/√Hz); suited for less sensitive, cost-sensitive applications. | Choose LMV324QDRQ1 when input common-mode range down to V− is required and lower precision is acceptable. |
Compared with TLV2264AQDG4, TLV2264AIDR lacks automotive qualification and long-term traceability, while LMV324QDRQ1 trades offset and noise performance for broader input voltage range and lower cost-making TLV2264AQDG4 optimal for high-accuracy, low-noise automotive sensor interfaces.

FAQ
What is the maximum input offset voltage specification for TLV2264AQDG4 over temperature?
The TLV2264AQDG4 has a maximum input offset voltage of 950 µV at TA = 25°C and 1500 µV across the full −40°C to 125°C operating range. This A-grade specification is guaranteed and tested per AEC-Q100 requirements, ensuring predictable DC error in automotive sensor signal chains without calibration.
Does TLV2264AQDG4 support true rail-to-rail input operation?
No, TLV2264AQDG4 features rail-to-rail *output* swing but not 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, per the recommended operating conditions table in the datasheet.
What packaging and environmental qualifications does TLV2264AQDG4 have?
TLV2264AQDG4 is supplied in a 14-pin SOIC (D) package and is qualified per AEC-Q100 Grade 1 for automotive applications. It includes Q-temp automotive support: configuration control, print support, and qualification to automotive reliability standards including HTOL, TC, and HAST.
