Product details
Overview
TLC2274EPWRQ1 from Texas Instruments is a quad rail-to-rail output operational amplifier qualified for automotive applications per AEC-Q100. It delivers 2.2 MHz gain-bandwidth, 3.6 V/μs slew rate, and 9 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity signal conditioning in single- or split-supply systems up to ±8 V. Its 1 pA typical input bias current and rail-inclusive common-mode range support piezoelectric transducer interfaces and precision ADC driver stages.
For engineers reviewing the TLC2274EPWRQ1 datasheet, TLC2274EPWRQ1 pinout, TLC2274EPWRQ1 application, or TLC2274EPWRQ1 equivalent, key selection criteria include guaranteed operation from −40°C to +150°C, low-offset stability over temperature (2 μV/°C), and validated 10-year life at 105°C junction temperature - critical for under-hood and powertrain control modules.
Technical Context
The TLC2274EPWRQ1 uses Texas Instruments' LinCMOS™ silicon gate process to achieve ultra-low input bias current (1 pA typ) and stable input offset voltage (≤2500 μV max at 25°C). Its rail-to-rail output stage operates with supply voltages from ±2.2 V to ±8 V, delivering full-swing capability into 10 kΩ loads while maintaining phase margin ≥50° at unity gain.
It features fully specified performance across both single-supply (VDD = 5 V) and split-supply (VDD± = ±5 V) configurations, with common-mode input range extending to the negative rail and supply rejection ratio ≥80 dB. The device includes integrated ESD protection (±2500 V HBM, ±1500 V CDM) and is characterized for extreme-temperature reliability per TI's high-temperature product standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports dual-rail automotive sensor interfaces and industrial analog front-ends without level-shifting. |
| Gain-Bandwidth Product | 2.25 MHz (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 (typ at ±5 V) - ensures <3.2 μs settling to 0.01% for ±2.3 V steps, suitable for fast-settling ADC drivers. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - 2× lower than legacy CMOS op-amps, critical for low-level sensor amplification. |
| Input Bias Current | 1 pA (typ at 25°C) - preserves signal integrity in high-impedance pH, thermopile, or photodiode circuits. |
| Operating Temperature | −40°C to +150°C - qualified for engine control units, transmission controllers, and battery management systems. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct interfacing with ground-referenced sensors in single-supply designs. |
Pinout & Package
TLC2274EPWRQ1 is housed in a 14-pin TSSOP package (6.60 mm × 5.10 mm body size) with exposed thermal pad. Pin functions are identical across all four amplifiers in the quad configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD+ | Positive supply rail | Accepts +2.2 V to +8 V (single-supply) or connects to positive rail in split-supply mode. |
| VDD− | Negative supply rail / GND | Accepts −2.2 V to −8 V or 0 V (single-supply); common return for all four amplifiers. |
| IN+ (A–D) | Non-inverting input (per channel) | High-impedance node (10¹² Ω) supporting direct connection to passive sensors or filter networks. |
| IN− (A–D) | Inverting input (per channel) | Differential input voltage range: ±16 V - accommodates transient-tolerant feedback configurations. |
| OUT (A–D) | Amplifier output (per channel) | Rail-to-rail swing: within 150 mV of rails at ±1 mA load - maximizes dynamic range into ADC reference buffers. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 150 mV of VDD+ and VDD− at ±1 mA load - eliminates need for external level-shifting when driving 12-bit+ SAR ADCs. |
| AEC-Q100 qualification | Qualified for automotive Grade 0 (−40°C to +150°C) with 1000-hour life test at max rated temperature - meets ASIL-B system requirements. |
| Low input offset drift | 2 μV/°C max - reduces calibration burden in wide-temperature-range current sensing and pressure transducer signal chains. |
| Ultra-low input bias current | 1 pA typical - prevents signal degradation in >100 MΩ source impedance applications like electrochemical sensors. |
| Integrated macromodel | PSpice-compatible Boyle model included - enables accurate simulation of settling time, output swing, and THD+N before prototyping. |
Applications
| Engine Control Unit Signal Conditioning | Automotive Cabin Pressure Sensor Interface |

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 |
|---|---|---|---|
| TLV2474QDRQ1 | Lower supply current (650 μA vs 6 mA per amp), but reduced GBW (1.8 MHz) and higher noise (17 nV/√Hz). | Better suited for ultra-low-power body control modules; insufficient bandwidth for fast ADC drivers. | Select TLV2474QDRQ1 only when quiescent current is primary constraint and bandwidth <150 kHz suffices. |
| OPA4376QDRQ1 | Higher precision (50 μV max VIO), lower noise (7.5 nV/√Hz), but narrower supply range (±1.75 V to ±3.6 V). | Optimized for low-voltage ADAS camera ISPs; incompatible with 5 V or ±5 V automotive subsystems. | Choose OPA4376QDRQ1 for high-accuracy vision processing; avoid for engine or chassis control due to supply limitation. |
Compared with TLV2474QDRQ1 and OPA4376QDRQ1, TLC2274EPWRQ1 uniquely balances wide supply range (±8 V), high temperature rating (150°C), and rail-to-rail output in a cost-optimized quad package - making it the default choice for general-purpose automotive analog signal chains where robustness and flexibility outweigh ultra-low-power or sub-100 μV offset requirements.

FAQ
What is the maximum operating temperature for TLC2274EPWRQ1?
TLC2274EPWRQ1 is qualified for continuous operation from −40°C to +150°C ambient temperature, with validated 1000-hour life testing at maximum rated junction temperature. This rating is explicitly confirmed in the SGLS416 datasheet's Recommended Operating Conditions and Thermal Information sections, supporting use in under-hood engine control and transmission modules.
Does TLC2274EPWRQ1 support single-supply operation?
Yes, TLC2274EPWRQ1 is fully specified for single-supply operation at VDD = 5 V, with common-mode input range extending to the negative rail (GND) and rail-to-rail output swing. The datasheet provides complete electrical characteristics and operating conditions for both 5 V and ±5 V configurations, including input voltage range, output swing, and CMRR performance.
What is the input bias current specification for TLC2274EPWRQ1?
TLC2274EPWRQ1 has a typical input bias current of 1 pA at 25°C, with a maximum of 60 pA across the full −40°C to +150°C temperature range. This ultra-low value is enabled by TI's LinCMOS™ process and is critical for high-impedance sensor interfaces such as piezoelectric transducers and electrochemical cells.
Is TLC2274EPWRQ1 pin-compatible with standard TLC2274 variants?
TLC2274EPWRQ1 uses the same 14-pin TSSOP (PW) package and identical pinout as non-automotive TLC2274 variants (e.g., TLC2274IPW), including VDD+, VDD−, IN+, IN−, and OUT assignments for all four channels. However, the Q1 suffix denotes AEC-Q100 qualification and enhanced high-temperature screening - not a pinout change.
What packaging and thermal metrics apply to TLC2274EPWRQ1?
TLC2274EPWRQ1 is supplied in a 14-pin TSSOP package (PW) with 6.60 mm × 5.10 mm body size and thermal metrics including RθJA = 106.0°C/W, RθJC(top) = 35.5°C/W, and ψJB = 47.1°C/W. These values are documented in Section 6.4 of the SGLS416 datasheet and support thermal design for high-power-density automotive PCB layouts.
