Product details
Overview
TLC2264AQPWRQ1 from Texas Instruments is a quad rail-to-rail output operational amplifier qualified for automotive applications (−40°C to 125°C), featuring 950 µV max input offset voltage at 25°C, 12 nV/√Hz input noise at 1 kHz, 1 pA typical input bias current, and 500 µA max supply current per amplifier. It enables precision signal conditioning in battery-powered sensor interfaces and ADC front-ends.
For engineers reviewing the TLC2264AQPWRQ1 datasheet, TLC2264AQPWRQ1 pinout, TLC2264AQPWRQ1 application, or TLC2264AQPWRQ1 equivalent, key selection criteria include its A-grade offset voltage spec, rail-to-rail output swing, low-noise CMOS architecture, automotive temperature qualification, and TSSOP-14 packaging for space-constrained vehicle subsystems.
Technical Context
The TLC2264AQPWRQ1 implements a CMOS-input, rail-to-rail output op-amp topology optimized for low-power precision analog signal paths. Its input stage delivers ultra-low bias current (1 pA typ) and high common-mode rejection (83 dB typ), while the output stage supports full-swing operation from VDD− to VDD+ across single- or split-supply configurations.
It operates over ±2.2 V to ±8 V supply ranges with guaranteed performance at 5 V and ±5 V. The device includes ESD protection exceeding 2000 V (MIL-STD-883, Method 3015) and 200 V (machine model), and is fully characterized for automotive-grade reliability including long-term offset drift of 0.003 µV/month.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 950 µV max at 25°C - enables DC-coupled precision amplification without significant zero-error contribution in sensor signal chains. |
| Supply Current | 1 mA max (four amplifiers) - supports low-quiescent-power operation in always-on automotive modules. |
| Input Bias Current | 1 pA typ - preserves signal integrity when interfacing with high-impedance sources like piezoelectric transducers. |
| Equivalent Input Noise | 12 nV/√Hz at 1 kHz - provides clean amplification for low-level analog signals in engine control or cabin sensing. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct connection to ground-referenced sensors in single-supply systems. |
| Output Swing | Rail-to-rail - maximizes dynamic range when driving SAR or delta-sigma ADCs with 0–5 V or ±2.5 V reference rails. |
| Gain-Bandwidth Product | 0.71 MHz at VDD = 5 V - sufficient for anti-aliasing filters, thermistor linearization, and slow-control-loop compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434QPWRQ1 | Higher supply current (1.25 mA), lower offset (600 µV max), no rail-to-rail input. | Better DC accuracy but higher power; unsuitable for ground-sensing configurations due to limited VICR. | Select when ultra-low offset dominates over power and input range requirements. |
| TLC2274AQDRQ1 | Higher slew rate (1.7 V/µs), higher noise (25 nV/√Hz), SOIC-14 package only. | Better AC performance for active filters, but larger footprint and reduced noise immunity in sensor paths. | Select when bandwidth >1 MHz is required and TSSOP packaging is not mandatory. |
Compared with TLV2434QPWRQ1 and TLC2274AQDRQ1, the TLC2264AQPWRQ1 offers the optimal balance of low power (1 mA), rail-to-rail output, and A-grade offset in a space-saving TSSOP-14 package-making it preferred for cost- and size-sensitive automotive sensor nodes where moderate bandwidth suffices.

FAQ
What is the operating temperature range for the TLC2264AQPWRQ1?
The TLC2264AQPWRQ1 is qualified for automotive applications with a guaranteed operating free-air temperature range of −40°C to 125°C. This specification is validated per AEC-Q100 requirements and applies across all electrical parameters in the datasheet's "recommended operating conditions" table.
Does the TLC2264AQPWRQ1 support single-supply operation?
Yes, the TLC2264AQPWRQ1 fully supports single-supply operation from 4.4 V to 8 V. Its common-mode input voltage range extends to the negative rail (VDD−/GND), and its rail-to-rail output swings within 150 mV of both supply rails-enabling direct interface with 0–5 V ADCs without level-shifting circuitry.
What is the maximum supply current for the TLC2264AQPWRQ1?
The TLC2264AQPWRQ1 draws a maximum supply current of 1 mA (four amplifiers total) across the full temperature range (−40°C to 125°C) under no-load conditions. At 25°C, typical consumption is 0.85 mA, making it suitable for always-on automotive subsystems with strict power budgets.
How does the TLC2264AQPWRQ1 differ from the standard TLC2264QPWRQ1?
The TLC2264AQPWRQ1 features tighter DC specifications versus the TLC2264QPWRQ1: 950 µV max input offset voltage (vs. 2.5 mV) and 2 µV/°C max temperature coefficient (vs. unspecified for Q-grade). Both share identical pinout, package, AC performance, and automotive qualification-making the "A" suffix the choice for precision-critical signal chains.
Is the TLC2264AQPWRQ1 pin-compatible with other TSSOP-14 quad op-amps?
The TLC2264AQPWRQ1 uses the industry-standard TSSOP-14 pinout for quad op-amps (per TI's D/PW package drawing), matching pin functions with devices such as TLV2434 and TLC2274 in the same package. However, differences in input stage architecture, biasing, and ESD structure mean functional compatibility must be verified per application-not assumed from pin alignment alone.
