Product details
Overview
TLC2272MD 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 rail-to-rail output swing - enabling high-fidelity interfacing with ADCs in battery-powered instrumentation.
For engineers reviewing the TLC2272MD datasheet, TLC2272MD pinout, TLC2272MD application, or TLC2272MD equivalent, key selection criteria include input offset voltage (≤950 µV max), ultra-low input bias current (1 pA typ), common-mode input range extending to negative rail, CMRR (75 dB min), and Q-temperature grade (–40°C to +125°C) suitability for automotive and industrial sensing.
Technical Context
The TLC2272MD uses 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−, and its output can drive within 15 mV of either supply rail under light load (±20 µA).
This device operates across ±2.2 V to ±8 V supplies and is fully characterized at ±5 V and 5 V single-supply conditions. It features 10¹² Ω differential and common-mode input resistance, 75 dB minimum CMRR, and 95 dB typical PSRR - making it suitable for high-impedance transducer interfaces where DC accuracy and AC fidelity are both critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide industrial and automotive supply rails including ±5 V and ±3.3 V systems |
| Gain-Bandwidth Product | 2.25 MHz - enables stable unity-gain buffering and closed-loop amplification up to ~200 kHz with 10× gain |
| Slew Rate | 3.6 V/µs - supports fast settling for sensor signals and moderate-speed data acquisition |
| Input Offset Voltage | ≤950 µV (max, TA = 25°C) - ensures <1 LSB error when driving 12-bit ADCs with 2.5-V reference |
| Input Bias Current | 1 pA (typical) - preserves signal integrity from high-impedance sources like piezoelectric sensors |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - 2× lower than TLC272, critical for low-level analog signal amplification |
| Common-Mode Input Range | Extends to VDD− - allows direct interface with ground-referenced sensors without level-shifting |
Pinout & Package
Package: SOIC (8-pin), body size 3.91 mm × 4.90 mm. RoHS-compliant, moisture sensitivity level (MSL) 1.

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/ch vs. 2.4 mA total), lower VIO (350 µV max), but only rated to 125°C (not –40°C to +125°C) | Lacks full automotive temperature range; better for commercial-grade portable equipment where ultra-low offset dominates | Choose TLV2432IDR if VIO < 500 µV is mandatory and extended low-temperature operation is not required |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, 0.02 µV/°C drift, but higher cost and 360-kHz GBW limits bandwidth-critical designs | Superior DC precision at expense of speed; unsuitable for >100-kHz signal paths or fast-settling applications | Choose OPA2333AIDR only when microvolt-level offset stability over time and temperature outweighs need for 2.25-MHz bandwidth |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2272MD uniquely balances rail-to-rail output, 1-pA input bias, 2.25-MHz bandwidth, and full Q-temp qualification - making it optimal for cost-sensitive, high-impedance, wide-temperature industrial and automotive sensor interfaces where both AC and DC performance matter.

FAQ
What is the maximum operating supply voltage for the TLC2272MD?
The TLC2272MD supports a supply voltage range of ±2.2 V to ±8 V. Absolute maximum ratings specify ±8 V on VDD+ and VDD− terminals. Operation beyond this risks permanent damage. For reliable long-term use, TI recommends staying within ±2.2 V to ±8 V under recommended operating conditions, with derating applied above 85°C ambient.
Does the TLC2272MD support single-supply operation?
Yes, the TLC2272MD is fully specified for single-supply operation. With VDD−/GND tied to 0 V and VDD+ at 5 V, it maintains rail-to-rail output swing and common-mode input range extending to ground. Input common-mode range is 0 V to 3.5 V, and output swings from 15 mV to 4.99 V at light load - ideal for interfacing with 5-V or 3.3-V ADCs.
What is the input offset voltage specification for the TLC2272MD?
The TLC2272MD (M-grade variant) guarantees a maximum input offset voltage of 950 µV at TA = 25°C. Over the full operating temperature range (–55°C to +125°C), the max is 1500 µV. This is specified for the "A" version (TLC2272AM), and the standard TLC2272M has a 2500-µV max at 25°C. Always verify the suffix: "A" denotes tighter VIO grading.
Is the TLC2272MD pin-compatible with the TLC2272CDR?
No - the TLC2272MD is not pin-compatible with the TLC2272CDR. While both are 8-pin SOIC dual op-amps, the "M" suffix denotes Q-temperature grade (–40°C to +125°C) and military/aerospace screening, whereas "C" indicates commercial grade (0°C to +70°C). Pinout is identical, but electrical specifications, reliability testing, and qualification differ significantly. PCB layout may be reused, but system-level validation is required.
What package options are available for the TLC2272MD?
The TLC2272MD is offered exclusively in the SOIC-8 (D package) with body dimensions 3.91 mm × 4.90 mm. Unlike the broader TLC2272 family (which includes TSSOP, PDIP, and CFP variants), the "M" grade is standardized to SOIC-8 for mechanical robustness and thermal reliability in demanding environments. No alternate packages are orderable for the MD suffix.
