Product details
Overview
TLC2274AQPWRG4Q1 from Texas Instruments is a quad, rail-to-rail output, LinCMOS™ operational amplifier qualified to AEC-Q100 Grade 1 (–40°C to 125°C), with 9 nV/√Hz input voltage noise at 1 kHz, 3.6 V/μs slew rate, and 950 μV maximum input offset voltage at 25°C - deployed in automotive body control modules and battery management systems.
For engineers reviewing the TLC2274AQPWRG4Q1 datasheet, TLC2274AQPWRG4Q1 pinout, TLC2274AQPWRG4Q1 application, or TLC2274AQPWRG4Q1 equivalent, key selection criteria include rail-to-rail output swing, low 1-pA typical input bias current, functional safety documentation support, ±2.2 V to ±8 V supply operation, and SOIC-14 or TSSOP-14 package compatibility.
Technical Context
The TLC2274AQPWRG4Q1 implements a CMOS-input, rail-to-rail output op-amp architecture optimized for precision signal conditioning in single- or split-supply automotive environments. It supports common-mode input voltage down to the negative rail and delivers full-swing output across supply rails - critical for interfacing with 12-bit+ ADCs in constrained voltage domains.
Its 2.2 MHz gain-bandwidth product, 75 dB typical CMRR, and 95 dB supply-voltage rejection ratio enable stable closed-loop performance in noisy powertrain and chassis control subsystems. The device is fully characterized at both 5 V single-supply and ±5 V dual-supply conditions per AEC-Q100 requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434-Q1 | Higher 10 V/μs slew rate but 12 nV/√Hz noise; 1.8 V to 6 V supply only | Better for high-speed PWM current sensing; unsuitable for ±5 V systems or low-noise sensor front-ends | Select when >5 MHz closed-loop bandwidth required and noise budget allows ≥12 nV/√Hz |
| LMV339-Q1 | Quad comparator (not op-amp); open-drain outputs; no linear amplification capability | Used for threshold detection only - cannot replace TLC2274AQPWRG4Q1 in amplifier or filter roles | Only consider if application requires voltage window comparators, not analog signal conditioning |
Compared with TLV2434-Q1 and LMV339-Q1, the TLC2274AQPWRG4Q1 uniquely balances low noise (9 nV/√Hz), rail-to-rail output, AEC-Q100 Grade 1 qualification, and dual-supply operation - making it the sole option among the three for precision DC-coupled automotive sensor interfaces requiring both accuracy and flexibility.

FAQ
What is the maximum input offset voltage specification for TLC2274AQPWRG4Q1?
The TLC2274AQPWRG4Q1 has a maximum input offset voltage of 950 μV at TA = 25°C, as specified in the electrical characteristics table for the 'A' grade variant. This value is guaranteed across the full operating temperature range of –40°C to 125°C, with a typical temperature coefficient of 2 μV/°C - ensuring predictable drift behavior in engine bay deployments where the TLC2274AQPWRG4Q1 operates.
Does TLC2274AQPWRG4Q1 support single-supply operation?
Yes, the TLC2274AQPWRG4Q1 is fully specified for single-supply operation at 5 V, with common-mode input voltage extending to the negative rail (VDD−) and rail-to-rail output swing. Its input stage functions correctly with VIC down to VDD−, and output delivers >4.9 V peak-to-peak into 10 kΩ at 5 V supply - making the TLC2274AQPWRG4Q1 suitable for 3.3 V or 5 V microcontroller-based automotive subsystems without level-shifting circuitry.
What package options are available for TLC2274AQPWRG4Q1?
The TLC2274AQPWRG4Q1 is offered in two automotive-qualified packages: 14-pin SOIC (D) with body size 8.65 mm × 3.91 mm, and 14-pin TSSOP (PW) with body size 5.00 mm × 4.40 mm. Both packages are RoHS-compliant, moisture sensitivity level 1, and qualified to AEC-Q100 - with thermal resistance RθJA of 83.8°C/W (SOIC) and 111.6°C/W (TSSOP), enabling reliable operation in under-hood environments where the TLC2274AQPWRG4Q1 is commonly deployed.
Is functional safety documentation available for TLC2274AQPWRG4Q1?
Yes, functional safety documentation is available for the TLC2274AQPWRG4Q1, including FIT rate calculation, failure mode effect analysis (FMEA), and diagnostic coverage guidance aligned with ISO 26262 ASIL-B development requirements. While the documentation set is shared with the TLC2272A-Q1 variant, it applies directly to the TLC2274AQPWRG4Q1 due to identical process, architecture, and qualification testing - supporting its use in safety-critical automotive control units where the TLC2274AQPWRG4Q1 performs analog signal conditioning.
How does the noise performance of TLC2274AQPWRG4Q1 compare to legacy automotive op-amps?
The TLC2274AQPWRG4Q1 delivers 9 nV/√Hz input voltage noise at 1 kHz - two times lower than competitive CMOS op-amps cited in the datasheet. This 3 dB improvement reduces integrated noise in 10 Hz–100 kHz bandwidths, directly enhancing effective resolution in 16-bit sensor interfaces. For example, in a piezoelectric knock sensor front-end, the TLC2274AQPWRG4Q1 achieves 1.4 μVPP integrated noise (0.1–10 Hz), outperforming predecessors by >40%, which is measurable in actual engine control unit validation using the TLC2274AQPWRG4Q1.
