Product details
Overview
TLC2272AMDG4 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, ±5 V supply operation, and maximum 950 µV input offset voltage at 25°C - enabling high-fidelity analog front-ends in battery-powered sensor interfaces.
For engineers reviewing the TLC2272AMDG4 datasheet, TLC2272AMDG4 pinout, TLC2272AMDG4 application, or TLC2272AMDG4 equivalent, this page provides verified electrical specifications, SOIC-8 package terminal mapping, rail-to-rail output behavior under split-supply conditions, and validated alternative options for industrial transducer signal chains and ADC driver stages.
Technical Context
The TLC2272AMDG4 uses Advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typical) and low noise. Its input stage operates with common-mode voltage range extending to the negative rail, supporting single-supply configurations down to 4.4 V or split supplies from ±2.2 V to ±8 V.
It features unity-gain stable compensation, 75 dB minimum CMRR and PSRR at 25°C, and is fully characterized across –55°C to +125°C for military-grade reliability. The device exhibits 1.7 V/µs minimum slew rate and 10 MHz small-signal bandwidth under full temperature range, with guaranteed 0.01% settling in ≤3.2 µs for ±2.3 V steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide industrial and automotive supply rails without external regulation |
| Input Offset Voltage (max) | 950 µV at 25°C - enables DC-coupled precision amplification with <0.1% error in 1 V full-scale systems |
| Gain-Bandwidth Product | 2.25 MHz at ±5 V - sufficient for anti-aliasing filters and sensor signal conditioning up to ~200 kHz |
| Slew Rate (typ) | 3.6 V/µs - allows clean 100 kHz sine wave output at 2 VPP without distortion |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - 2× lower than TLC272, critical for piezoelectric and high-impedance source interfacing |
| Input Bias Current (typ) | 1 pA - preserves signal integrity in pH electrodes, photodiode TIA, and leakage-sensitive measurement circuits |
| Common-Mode Input Range | Extends to VDD− - permits direct sensing of ground-referenced signals in single-supply systems |

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 | Lower supply current (1.3 mA vs 2.4 mA), lower slew rate (1.5 V/µs), no M-grade temp rating | Optimized for ultra-low-power portable devices; not qualified for extended temperature or high-speed settling | Select when power budget <1.5 mA/channel is mandatory and bandwidth <500 kHz suffices |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C offset drift, higher cost, 360 µA supply current | Required for <1 µV total offset drift over –40°C to +85°C; unsuitable for >100 kHz signal paths | Select when long-term DC stability dominates over AC performance and cost sensitivity is low |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2272AMDG4 uniquely balances military-grade temperature operation, rail-to-rail output, 2.25 MHz bandwidth, and 1 pA input bias - making it optimal for ruggedized sensor front-ends where moderate speed and extreme bias current sensitivity coexist.

FAQ
What is the maximum operating temperature range for the TLC2272AMDG4?
The TLC2272AMDG4 is rated for operation from –55°C to +125°C, meeting MIL-PRF-38535 Class M specifications. This extended range is validated across all electrical parameters including input offset voltage, CMRR, and slew rate - making TLC2272AMDG4 suitable for downhole oilfield tools, avionics black boxes, and engine control units where ambient temperatures exceed commercial or industrial limits.
Does the TLC2272AMDG4 support single-supply operation?
Yes, the TLC2272AMDG4 supports true single-supply operation from 4.4 V to 16 V. Its input common-mode range extends to the negative rail (VDD−/GND), and its rail-to-rail output delivers full swing from near 0 V to within 15 mV of VDD+. This enables direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without level-shifting circuitry - confirmed in TI's SLOS190H datasheet Section 6.3.
What is the input offset voltage specification for the TLC2272AMDG4?
The TLC2272AMDG4 has a maximum input offset voltage of 950 µV at TA = 25°C, per the "A" grade designation in its part number. This is guaranteed across the full military temperature range (–55°C to +125°C) at ≤1500 µV. The typical value is 300 µV, and temperature coefficient is 2 µV/°C - enabling predictable calibration in precision analog front-ends.
Can the TLC2272AMDG4 drive capacitive loads directly?
The TLC2272AMDG4 is unity-gain stable with capacitive loads up to 100 pF, as verified in datasheet Sections 6.5 and 6.6. For loads >100 pF, TI recommends adding a series isolation resistor (typically 10–100 Ω) between the output and capacitance to maintain phase margin >50° and prevent peaking or oscillation - a design practice confirmed in Application Report SLOA058B.
Is the TLC2272AMDG4 pin-compatible with the standard TLC2272 series?
Yes, the TLC2272AMDG4 uses the industry-standard SOIC-8 (D) package with identical pinout to TLC2272, TLC2272A, and TLC2272M variants. Pin 1 is OUT A, Pin 2 is IN− A, Pin 3 is IN+ A, Pin 4 is VDD−/GND, Pin 5 is IN+ B, Pin 6 is IN− B, Pin 7 is OUT B, and Pin 8 is VDD+. No PCB layout changes are required when upgrading from commercial or industrial grades to the M-grade TLC2272AMDG4.
