Product details
Overview
TLC2272QDRQ1 from Texas Instruments is a dual, rail-to-rail output, automotive-grade LinCMOS™ operational amplifier qualified to AEC-Q100 Grade 1 (–40°C to 125°C), featuring 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. It supports single- or split-supply operation up to ±8 V and is used in precision signal conditioning for high-impedance sensors in battery management systems and engine control units.
For engineers reviewing the TLC2272QDRQ1 datasheet, TLC2272QDRQ1 pinout, TLC2272QDRQ1 application, or TLC2272QDRQ1 equivalent, this page delivers verified electrical specs, SOIC-8 package details, functional safety documentation support, and validated automotive alternatives - all aligned with TI's SGLS007G production data sheet (Rev. G, Aug 2022).
Technical Context
The TLC2272QDRQ1 employs LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typical) and rail-to-rail output swing, enabling full dynamic range utilization when interfacing with 12-bit+ ADCs in single-supply automotive domains. Its common-mode input range extends to the negative rail, supporting ground-referenced sensor front-ends without level-shifting.
Designed for functional safety–capable systems, it includes documented support for ISO 26262 ASIL-B development workflows, with characterized parametric drift over temperature (2 µV/°C αVIO) and long-term stability (0.002 µV/month). The device maintains phase margin ≥50° and gain margin ≥10 dB under 100 pF capacitive load conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432QDRQ1 | Higher output drive (±100 mA vs ±50 mA), wider input voltage range (to VDD− − 0.2 V), but higher input offset (1.5 mV max) | Better suited for driving heavy capacitive loads or low-impedance actuators; less optimal for precision DC sensing | Select TLV2432QDRQ1 when output current >50 mA or input common-mode extension beyond VDD− is required |
| OPA2333AQDRQ1 | Zero-drift architecture, 2 µV max VIO, 0.02 µV/°C drift, but lower GBW (350 kHz) and slew rate (0.16 V/µs) | Superior for ultra-stable DC measurements (e.g., strain gauges); unsuitable for >10-kHz signal chains | Select OPA2333AQDRQ1 only for sub-mV DC accuracy needs where bandwidth <100 kHz suffices |
Compared with TLV2432QDRQ1 and OPA2333AQDRQ1, the TLC2272QDRQ1 balances rail-to-rail output, low noise (9 nV/√Hz), and 2.25-MHz bandwidth - making it optimal for mid-speed automotive sensor interfaces requiring both precision and dynamic response.

FAQ
What is the maximum supply voltage rating for the TLC2272QDRQ1?
The TLC2272QDRQ1 has an absolute maximum supply voltage rating of ±8 V across VDD+ and VDD− terminals. Operating within the recommended range of ±2.2 V to ±8 V ensures reliable rail-to-rail output swing and specified AC performance per TI's SGLS007G datasheet. Exceeding ±8 V risks permanent damage.
Does the TLC2272QDRQ1 support single-supply operation?
Yes, the TLC2272QDRQ1 fully supports single-supply operation - its common-mode input range includes the negative rail (VDD−), and output swings rail-to-rail. When powered from 0 V and +5 V, it accepts inputs down to 0 V and delivers outputs from near 0 V to near +5 V, enabling direct interface with 3.3 V or 5 V microcontrollers and ADCs.
Is the TLC2272QDRQ1 pin-compatible with the standard TLC2272IDR?
No - the TLC2272QDRQ1 is not pin-compatible with the commercial-grade TLC2272IDR. While both use SOIC-8 packaging, the Q1 variant includes enhanced ESD protection (HBM ±2000 V), extended temperature characterization, and functional safety documentation. Electrical pin functions match, but qualification scope and reliability testing differ significantly.
What is the input offset voltage specification for the TLC2272QDRQ1 over temperature?
The TLC2272QDRQ1 has a maximum input offset voltage of 1500 µV across the full operating range (–40°C to 125°C), with a typical temperature coefficient of 2 µV/°C. At 25°C, the maximum is 950 µV for the "A" grade variant - confirmed in Section 6.5 and 6.6 of the SGLS007G datasheet under ±5 V and 5 V supply conditions.
Can the TLC2272QDRQ1 drive a 100-pF capacitive load stably?
Yes - the TLC2272QDRQ1 is characterized for stable operation with 100-pF capacitive loads, maintaining ≥50° phase margin and ≥10 dB gain margin at unity gain (Section 6.5/6.6, SGLS007G). This makes it suitable for driving ADC input capacitance or long PCB traces without external isolation resistors.
