Product details
Overview
TLC2274QDRQ1 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 2.2 MHz gain-bandwidth product, 3.6 V/μs slew rate, and 9 nV/√Hz input voltage noise at 1 kHz. It delivers low input bias current (1 pA typical), low input offset voltage (≤950 μV max), and full rail-to-rail output swing for precision signal conditioning in automotive sensor interfaces and ADC drivers.
For engineers reviewing the TLC2274QDRQ1 datasheet, TLC2274QDRQ1 pinout, TLC2274QDRQ1 application, or TLC2274QDRQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade operating conditions, and real-world application mappings - all aligned to TI's SGLS007G revision G datasheet.
Technical Context
The TLC2274QDRQ1 implements a CMOS-input, rail-to-rail output op-amp architecture optimized for single-supply (2.2 V to 16 V) and split-supply (±2.2 V to ±8 V) operation. Its input stage supports common-mode voltage down to VDD− and up to VDD+ − 1.5 V, enabling direct interfacing with high-impedance sources like piezoelectric transducers.
It features internal compensation for unity-gain stability, 50° phase margin with 100 pF load, and robust ESD protection (HBM ±2000 V, CDM ±1000 V). The device is fully characterized across –40°C to 125°C and supports functional safety system design with documented failure modes and FIT data.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V (split) or 2.2 V to 16 V (single); enables flexible power architecture in 12 V automotive systems. |
| Gain-Bandwidth Product | 2.25 MHz (±5 V); supports stable closed-loop gain up to ~10× at 200 kHz for sensor amplification. |
| Slew Rate | 3.6 V/μs (typical); ensures <2.6 μs settling to 0.01% for 4.6 Vpp step, critical for fast ADC sampling. |
| Input Offset Voltage | ≤950 μV (max, TLC2274A-Q1 variant); reduces DC error in precision current sensing and battery voltage monitoring. |
| Input Bias Current | 1 pA (typical); preserves signal integrity when amplifying from >1 MΩ source impedances (e.g., thermistors). |
| Output Swing | Rail-to-rail (within 15 mV of rails at 200 μA); maximizes dynamic range into 12-bit+ SAR ADCs without level-shifting. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz; two times lower than competitive CMOS op amps, improving SNR in audio and sensor front-ends. |

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 | Lower supply current (1.2 mA/ch vs 1.5 mA/ch), but reduced GBW (1.8 MHz) and higher offset (1.5 mV max). | Better suited for ultra-low-power always-on modules; less ideal for high-speed sensor sampling. | Select TLV2434-Q1 only when supply current is primary constraint and bandwidth <1.8 MHz suffices. |
| OPA4197-Q1 | Higher precision (10 μV max offset), wider supply range (±2.25 V to ±18 V), but higher cost and larger SOIC-14 footprint. | Targeted at ASIL-D safety-critical subsystems requiring tighter DC accuracy and extended voltage headroom. | Choose OPA4197-Q1 when sub-50 μV offset and enhanced fault tolerance are mandatory for functional safety compliance. |
Compared with TLV2434-Q1 and OPA4197-Q1, the TLC2274QDRQ1 delivers optimal balance of rail-to-rail performance, 2.25 MHz bandwidth, AEC-Q100 Grade 1 reliability, and cost efficiency for mainstream automotive analog signal chains - especially where 950 μV offset and 3.6 V/μs slew rate meet system requirements.

FAQ
What is the maximum operating temperature for the TLC2274QDRQ1?
The TLC2274QDRQ1 is qualified to AEC-Q100 Grade 1 with an operating free-air temperature range of –40°C to 125°C. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, common-mode input range, and output drive capability - making it suitable for under-hood and cabin-mounted automotive applications where ambient temperatures exceed 105°C.
Does the TLC2274QDRQ1 support single-supply operation?
Yes, the TLC2274QDRQ1 fully supports single-supply operation from 2.2 V to 16 V. Its input common-mode range extends to the negative rail (VDD−), and its rail-to-rail output swings within 15 mV of both supply rails - enabling direct interface with microcontroller ADCs without external bias networks or level shifters.
What is the input offset voltage specification for the TLC2274QDRQ1?
The TLC2274QDRQ1 (standard grade) has a maximum input offset voltage of 2500 μV at TA = 25°C, while the TLC2274AQDRQ1 variant is specified at ≤950 μV max. Both versions are fully characterized over –40°C to 125°C, with temperature coefficient of 2 μV/°C - critical for maintaining accuracy in wide-temperature automotive environments.
Is the TLC2274QDRQ1 pin-compatible with other devices in the TLC227x-Q1 family?
Yes, the TLC2274QDRQ1 shares identical SOIC-14 pinout with TLC2274A-Q1, TLC2272-Q1 (SOIC-8), and TLC2272A-Q1 (SOIC-8). However, pin mapping differs between dual (8-pin) and quad (14-pin) variants - the TLC2274QDRQ1 uses Pins 1–4, 5–8, 9–11, and 12–14 for its four independent op-amp channels and supplies, as defined in Table 5-1 of the SGLS007G datasheet.
What packaging options are available for the TLC2274QDRQ1?
The TLC2274QDRQ1 is offered exclusively in the SOIC-14 (D package) with nominal body dimensions of 8.65 mm × 3.91 mm. TI does not list TSSOP-14 for this specific part number in the orderable addendum - only SOIC-14 is confirmed for TLC2274QDRQ1, distinguishing it from non-Q1 commercial variants that may offer multiple packages.
