Product details
Overview
TLC2272MDR from Texas Instruments is a dual rail-to-rail output operational amplifier designed for precision signal conditioning in low-power, high-impedance sensor interfaces. 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 950-µV maximum input offset voltage (TLC2272A-grade). It is used in battery-powered handheld monitoring systems interfacing with piezoelectric transducers.
For engineers reviewing the TLC2272MDR datasheet, TLC2272MDR pinout, TLC2272MDR application, or TLC2272MDR equivalent, key selection criteria include rail-to-rail output swing (±4.91 V at ±5 V supplies), ultra-low input bias current (1 pA typical), common-mode input range extending to negative rail, low-noise performance, and Q- or M-grade qualification for extended temperature operation.
Technical Context
The TLC2272MDR employs advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise. Its input stage supports common-mode voltages down to VDD−, enabling single-supply operation with ground-referenced inputs.
It features fully specified performance across ±2.2 V to ±8 V dual-supply ranges and operates over −55°C to +125°C (M-grade). The device exhibits 75 dB minimum CMRR and 80 dB minimum PSRR, ensuring stability in noisy industrial environments with varying supply conditions.
Key Specifications

|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide dual-supply operation including standard ±5 V and low-voltage ±2.5 V rails |
| Gain-Bandwidth Product | 2.25 MHz - enables stable unity-gain buffering and closed-loop amplification up to ~200 kHz with moderate gain |
| Slew Rate | 3.6 V/µs - supports fast settling of 0.5 V–to–2.5 V steps in ≤1.5 µs (0.1% accuracy) |
| Input Offset Voltage | ≤950 µV max (TA = 25°C) - ensures <0.1% error in 1-V full-scale precision DC amplification |
| Input Bias Current | 1 pA typical - preserves signal integrity in >1 GΩ source impedance applications (e.g., pH sensors, piezo elements) |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - provides high SNR in audio and instrumentation front-ends without added filtering |
| Common-Mode Input Range | Includes VDD− rail - allows direct interface to ground-referenced sensors in single-supply configurations |

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 quiescent current (1.2 mA vs. 2.4 mA), lower VOS (150 µV max), but only rated for −40°C to +125°C (I-grade) | Preferred for cost-sensitive industrial controls where extended cold temp is not required | Select TLV2432IDR when sub-200-µV offset is mandatory and M-grade temperature range is unnecessary |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VOS, 0.02 µV/°C drift, but higher supply current (17 µA per amp) and narrower supply range (±0.9 V to ±2.75 V) | Suitable for ultra-high-precision DC measurements, not for wide-supply or high-slew applications | Choose OPA2333AIDR only for microvolt-level DC stability needs; avoid if >±2.75 V supply or >1 V/µs slew is required |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2272MDR uniquely balances M-grade temperature resilience, rail-to-rail output, low noise, and ±8 V supply flexibility-making it optimal for ruggedized analog signal chains where long-term offset drift and extreme ambient operation are primary constraints.

FAQ
What is the operating temperature range for the TLC2272MDR?
The TLC2272MDR is an M-grade device qualified for continuous operation from −55°C to +125°C. This extended range is validated per MIL-STD-883 methods and supports deployment in aerospace, defense, and under-hood automotive applications where ambient extremes are routine. The TLC2272MDR maintains all electrical specifications-including 950 µV max input offset and 3.6 V/µs slew rate-across this full range.
Does the TLC2272MDR support single-supply operation?
Yes, the TLC2272MDR is fully specified for single-supply operation. With its common-mode input range extending to VDD− (including ground) and rail-to-rail output swing, it functions reliably with VDD+ = +5 V and VDD− = 0 V. Input signals can be referenced to ground, and output swings from near 0 V to near 5 V-enabling direct interface to SAR or sigma-delta ADCs without level-shifting circuitry.
What is the maximum output current capability of the TLC2272MDR?
The TLC2272MDR can source or sink up to ±50 mA per output (absolute maximum rating), but recommended continuous output current is ±20 mA to maintain thermal stability and output voltage accuracy. At ±1 mA load, the output remains within 150 mV of the supply rail (e.g., VOH ≥ 4.25 V at VDD+ = 5 V); at ±5 mA, VOL rises to ≤1.5 V and VOH drops to ≥4.25 V-values confirmed in the datasheet's electrical characteristics tables.
How does the TLC2272MDR compare to the standard TLC2272D in terms of performance?
The TLC2272MDR shares identical AC and DC electrical specifications with the TLC2272D (e.g., 2.25 MHz GBW, 3.6 V/µs slew rate, 9 nV/√Hz noise), but differs in temperature grading and screening. The "M" suffix denotes military/aerospace qualification (−55°C to +125°C), enhanced burn-in, and lot traceability per MIL-PRF-38535. The "DR" packaging denotes tape-and-reel delivery in SOIC-8 format-identical mechanical form factor to the D variant.
Is a SPICE model available for the TLC2272MDR?
Yes, Texas Instruments provides a verified PSpice macromodel for the TLC2272 family-including the TLC2272MDR-on the official product folder page. The model accurately reproduces key behaviors: rail-to-rail output saturation, input bias current, common-mode rejection, and small-signal frequency response up to 10 MHz. It is compatible with industry-standard simulators and supports transient, AC, and DC sweep analyses for front-end design validation.
