Product details
Overview
TLC2272QPWR from Texas Instruments is a dual rail-to-rail output operational amplifier designed for precision signal conditioning in low-voltage, low-power systems. 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 rail-to-rail output swing - enabling high-fidelity interfacing with ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2272QPWR datasheet, TLC2272QPWR pinout, TLC2272QPWR application, or TLC2272QPWR equivalent, key selection criteria include its ±2.2 V to ±8 V dual-supply operation, 950 µV maximum input offset voltage (TLC2272A grade), Q-temp automotive qualification, and TSSOP-8 package compatibility with space-constrained industrial monitoring designs.
Technical Context
The TLC2272QPWR uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise. Its input stage operates down to the negative rail, supporting single-supply configurations with ground-referenced inputs - critical for transducer interfaces where common-mode voltage may approach GND.
Internally compensated for unity-gain stability with 50° phase margin, it drives capacitive loads up to 100 pF without oscillation and supports closed-loop bandwidths up to 1 MHz at 2-VPP output swing. The device is fully specified across –40°C to +125°C for automotive-grade reliability.
Key Specifications

|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide dual-supply operation including ±5 V standard and low-voltage ±2.5 V systems |
| Gain-Bandwidth Product | 2.25 MHz - enables stable amplification of signals up to ~200 kHz at moderate closed-loop gains |
| Slew Rate | 3.6 V/µs - ensures faithful reproduction of fast 1–2 VPP signals at >100 kHz without distortion |
| Input Offset Voltage (max) | 950 µV - meets precision requirements for 12-bit ADC front-ends with ≤0.25% full-scale error contribution |

Pinout & Package
TLC2272QPWR is housed in an 8-pin TSSOP package (body size 4.40 mm × 3.00 mm) with exposed thermal pad (PW suffix), optimized for automated assembly and thermal performance in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel 1 - directly drives ADC input or next-stage filter |
| 2 | IN− A | Inverting input of Channel 1 - used for feedback configuration and differential sensing |
| 3 | IN+ A | Non-inverting input of Channel 1 - accepts high-impedance sensor signals with minimal loading |
| 4 | VDD−/GND | Negative supply or ground reference - establishes return path for both channels and bias network |
| 5 | IN+ B | Non-inverting input of Channel 2 - enables dual-channel signal conditioning on single IC |
| 6 | IN− B | Inverting input of Channel 2 - supports independent feedback networks per channel |
| 7 | OUT B | Amplified output of Channel 2 - provides second analog channel without additional footprint |
| 8 | VDD+ | Positive supply - powers both op-amp cores; requires local 100-nF decoupling to minimize PSRR impact |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full supply-range output (e.g., 0 V to 5 V on single 5-V supply), maximizing ADC input utilization |

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 |
|---|---|---|---|
| TLV2432IDR | Higher 1.2-mA/channel supply current; 2.5-V/µs slew rate; no Q-temp qualification | Optimized for higher-speed, non-automotive industrial use; lacks extended temperature validation | Select TLV2432IDR only if 2.25-MHz GBW is insufficient and ambient temperature remains ≤85°C |
| OPA2333AIDR | Zero-drift architecture; 0.02-µV/°C offset drift; 17-µV max VIO; 17-µA/ch supply current | Superior DC precision for long-term sensor calibration; lower power but reduced bandwidth (350 kHz) | Choose OPA2333AIDR when microvolt-level offset stability over temperature is required, not speed |

FAQ
What supply voltage ranges does the TLC2272QPWR support?
The TLC2272QPWR operates from ±2.2 V to ±8 V in dual-supply mode and from 4.4 V to 16 V in single-supply mode. This range accommodates standard ±5 V instrumentation systems, low-voltage ±2.5 V portable designs, and 5-V/3.3-V industrial logic interfaces - all while maintaining rail-to-rail output swing and specified AC performance.
Is the TLC2272QPWR qualified for automotive applications?
Yes, the TLC2272QPWR carries Q-temp automotive qualification per AEC-Q100, with guaranteed operation from –40°C to +125°C ambient temperature. It includes HBM ESD rating of ±2000 V and CDM rating of ±1000 V, meeting stringent reliability requirements for under-dash and engine-compartment electronics.
Does the TLC2272QPWR have rail-to-rail input capability?
No, the TLC2272QPWR features rail-to-rail *output* swing but its common-mode input voltage range extends only to VDD− (not beyond) and up to VDD+ −1.5 V. This allows ground-referenced inputs in single-supply use but does not support input signals exceeding the positive rail - unlike true rail-to-rail input amplifiers.
What is the maximum input offset voltage specification for TLC2272QPWR?
The TLC2272QPWR is part of the TLC2272A variant group, with a maximum input offset voltage of 950 µV at TA = 25°C and 1500 µV across the full –40°C to +125°C operating range. This specification is guaranteed and tested, enabling predictable error budgeting in precision 12-bit ADC front-ends.
Can TLC2272QPWR drive capacitive loads directly?
Yes, the TLC2272QPWR is internally compensated for unity-gain stability and can safely drive up to 100 pF capacitive loads without oscillation, as verified by 50° phase margin and 10 dB gain margin in test conditions. For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain stability.
