Product details
Overview
TLC2272AQDRG4Q1 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). It delivers 2.2 MHz gain-bandwidth, 3.6 V/μs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and ≤950 μV maximum input offset voltage at 25°C - enabling precision signal conditioning in battery management systems and engine control units.
For engineers reviewing the TLC2272AQDRG4Q1 datasheet, TLC2272AQDRG4Q1 pinout, TLC2272AQDRG4Q1 application, or TLC2272AQDRG4Q1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive operating conditions (±2.2 V to ±8 V supply, –40°C to 125°C), and real-world functional alternatives for safety-critical analog front-ends.
Technical Context
The TLC2272AQDRG4Q1 implements a CMOS-input, rail-to-rail output architecture optimized for single- and split-supply operation. Its input stage supports common-mode voltage down to the negative rail (VDD−), while its output swings within 15 mV of both rails under light load (±20 μA), ensuring full dynamic range when driving ADCs or low-voltage logic interfaces.
It features functional safety documentation support per ISO 26262, with characterized parameters across –40°C to 125°C including input offset voltage drift (2 μV/°C), supply rejection (≥80 dB), and CMRR (≥70 dB). All electrical specs are fully tested at 5 V and ±5 V supplies per AEC-Q100 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide automotive battery transients and dual-rail sensor interfaces |
| Gain-Bandwidth Product | 2.2 MHz typical - enables stable closed-loop operation up to ~200 kHz with unity-gain stability |
| Slew Rate | 3.6 V/μs typical - supports fast settling for pulse-width modulated (PWM) feedback signals |
| Input Offset Voltage | ≤950 μV max at 25°C - ensures <0.02% error in 5 V full-scale current-sense amplification |
| Input Bias Current | 1 pA typical - preserves signal integrity in high-impedance piezoelectric or pH sensor circuits |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - critical for low-level audio preamplification and thermocouple signal chains |
| Common-Mode Input Range | Extends to VDD− - allows direct sensing of ground-referenced shunt resistors without level-shifting |
Pinout & Package
Package: SOIC-8 (D package), 4.90 mm × 3.91 mm body size, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, Channel 1 | Delivers rail-to-rail swing; drives ADC inputs or comparator thresholds directly |
| 2OUT | Output, Channel 2 | Independent output; supports dual-path signal conditioning (e.g., differential pair + reference) |
| 1IN+ | Noninverting Input, Channel 1 | High-impedance node (10¹² Ω); accepts weak signals from sensors without loading |
| 1IN− | Inverting Input, Channel 1 | Used with feedback network for precise gain configuration or active filtering |
| 2IN+ | Noninverting Input, Channel 2 | Enables independent second channel for monitoring or redundancy in ASIL-B designs |
| 2IN− | Inverting Input, Channel 2 | Supports differential input configurations or summing junctions |
| VDD+ | Positive Supply | Highest potential rail; must be ≥ |VDD−| for proper rail-to-rail output swing |
| VDD− | Negative Supply | Lowest potential rail; defines lower bound of common-mode and output range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 15 mV of VDD+ and VDD− at ±20 μA - eliminates need for level-shifting before 12-bit ADCs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432QDRQ1 | Higher supply current (1.2 mA/channel vs 1.5 mA total), lower slew rate (1.5 V/μs), no AEC-Q100 functional safety documentation | Targeted at cost-sensitive, non-safety-critical body electronics; lacks FIT data and diagnostic coverage reports | Select when functional safety certification is not required and supply current budget permits higher quiescent draw |
| OPA2333AQDGKRQ1 | Zero-drift architecture, 0.02 μV/°C offset drift, 5.5 μVpp 0.1–10 Hz noise, but only 350 kHz GBW and 160 μA/ch supply current | Better DC precision for ultra-low-drift sensor bridges; insufficient bandwidth for PWM feedback loops >100 kHz | Select for high-accuracy DC measurements (e.g., pressure transducers) where speed is secondary to long-term stability |
Compared with TLV2432QDRQ1, TLC2272AQDRG4Q1 offers superior slew rate and functional safety support; compared with OPA2333AQDGKRQ1, it trades DC precision for higher bandwidth and lower noise in AC-coupled signal paths - making it optimal for automotive motor control and audio front-ends.
