Product details
Overview
TLC2274QPWRG4Q1 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 - designed for precision signal conditioning in automotive analog front-ends.
For engineers reviewing the TLC2274QPWRG4Q1 datasheet, TLC2274QPWRG4Q1 pinout, TLC2274QPWRG4Q1 application, or TLC2274QPWRG4Q1 equivalent, this device supports low-noise, high-impedance sensor interfacing (e.g., piezoelectric transducers), rail-to-rail ADC driving, and single-/split-supply operation across body control modules, battery management systems, and engine control units.
Technical Context
The TLC2274QPWRG4Q1 implements a CMOS-input, rail-to-rail output architecture optimized for automotive environments, featuring full characterization at ±5 V and 5 V supplies, common-mode input range extending to the negative rail, and functional safety documentation support. Its 1 pA typical input bias current and 950 μV maximum input offset voltage (TLC2274A-Q1 variant) enable stable DC-coupled amplification.
It delivers 2.2 MHz unity-gain bandwidth and 3.6 V/μs slew rate under 5 V or ±5 V operation, with thermal metrics including RθJA = 111.6°C/W (TSSOP-14 package), supporting reliable performance in thermally constrained automotive PCB layouts without external heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V or 4.4 V to 16 V - supports dual-rail and wide-range single-supply automotive power domains. |
| Gain-Bandwidth Product | 2.25 MHz typical at ±5 V - enables stable closed-loop operation up to ~200 kHz with moderate gain (e.g., AV = 10). |
| Slew Rate | 3.6 V/μs typical - ensures <2.6 µs settling to 0.01% for 4.6 VPP step, suitable for fast transient sensing. |
| Input Offset Voltage | ≤950 μV max (TLC2274A-Q1 spec) at 25°C - reduces DC error in precision current sensing and sensor amplification stages. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - two times lower than competitive CMOS op amps, critical for low-level audio and transducer signal integrity. |
| Input Bias Current | 1 pA typical - preserves signal fidelity when amplifying high-impedance sources (e.g., pH electrodes, piezo sensors). |
| Common-Mode Input Range | Extends to VDD− - allows direct interface with ground-referenced sensors in single-supply configurations. |
Pinout & Package
Package: TSSOP-14 (PW), body size 5.00 mm × 4.40 mm, moisture sensitivity level MSL-3, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, Channel 1 | High-impedance node for differential or single-ended signal routing; accepts inputs down to VDD−. |
| 1IN− | Inverting input, Channel 1 | Feedback path connection point; matched to 1IN+ for precision instrumentation topologies. |
| 1OUT | Output, Channel 1 | Rail-to-rail swing (e.g., 0.01 V to 4.99 V at 5 V supply) - directly drives SAR ADC reference buffers or comparators. |
| 2IN+ | Noninverting input, Channel 2 | Independent high-Z input for second sensor channel or auxiliary signal path. |
| 2IN− | Inverting input, Channel 2 | Enables dual-channel instrumentation amplifier configuration with shared gain-setting resistors. |
| 2OUT | Output, Channel 2 | Full rail-to-rail capability identical to 1OUT - supports parallel signal processing without level-shifting. |
| 3IN+ | Noninverting input, Channel 3 | Third independent input stage - used in multi-sensor monitoring (e.g., temperature + pressure + voltage). |
| 3IN− | Inverting input, Channel 3 | Supports active filtering or gain adjustment per channel without cross-talk. |
| 3OUT | Output, Channel 3 | Delivers conditioned output with same dynamic range and noise floor as other channels. |
| 4IN+ | Noninverting input, Channel 4 | Fourth dedicated input - enables full-bridge sensor excitation and differential readout in motor control feedback loops. |
| 4IN− | Inverting input, Channel 4 | Allows simultaneous four-channel acquisition with matched AC/DC response across all amplifiers. |
| 4OUT | Output, Channel 4 | Guaranteed rail-to-rail drive into ≥10 kΩ loads - eliminates need for external output buffers in most automotive interfaces. |
| VDD+ | Positive supply | Highest potential rail; must be ≥|VDD−| for proper biasing - accommodates asymmetric supplies (e.g., +5 V / –3.3 V). |
| VDD− | Negative supply | Lowest potential rail; defines reference for common-mode and output swing - enables true bipolar operation. |

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 (220 µA/channel vs 1.5 mA/channel), but reduced GBW (550 kHz) and higher input offset (1.5 mV max). | Better suited for ultra-low-power always-on monitoring; less appropriate for high-speed current sensing or audio paths. | Select TLV2434-Q1 only when power budget is <1 mA total and bandwidth <200 kHz is acceptable. |
| LMV884QMA/NOPB | Higher input bias current (100 pA vs 1 pA), wider supply range (2.7–12 V), no AEC-Q100 Grade 1 rating (only Grade 3). | Acceptable for infotainment or cabin comfort modules; not qualified for powertrain or ADAS-critical functions. | Choose LMV884QMA/NOPB only for non-safety-critical interior subsystems where cost is prioritized over long-term drift stability. |
Compared with TLV2434-Q1 and LMV884QMA/NOPB, the TLC2274QPWRG4Q1 uniquely balances rail-to-rail output, ultra-low input bias current, AEC-Q100 Grade 1 qualification, and 2.25 MHz bandwidth - making it the only option among the three qualified for precision, high-reliability automotive powertrain and chassis control loops.
