Product details
Overview
TLC2272AMDREPG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for precision, low-noise signal conditioning in extended-temperature industrial and aerospace applications. It delivers 2.2 MHz gain-bandwidth product, 3.6 V/µs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 950 µV maximum input offset voltage at 25°C - enabling high-fidelity amplification of piezoelectric sensor outputs and ADC interface circuits.
For engineers reviewing the TLC2272AMDREPG4 datasheet, TLC2272AMDREPG4 pinout, TLC2272AMDREPG4 application, or TLC2272AMDREPG4 equivalent, this device is selected for designs requiring guaranteed operation from −55°C to 125°C, single- or split-supply compatibility (±2.2 V to ±8 V), rail-to-rail output swing, and low-input-bias-current performance in high-impedance source interfaces.
Technical Context
The TLC2272AMDREPG4 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input impedance (>10¹² Ω) and ultra-low input bias current. Its fully differential input stage supports common-mode input voltage down to the negative rail (VDD−), making it suitable for single-supply transducer front-ends where ground-referenced signals must be amplified without level-shifting.
It features internal frequency compensation for unity-gain stability with 50° phase margin into 10 kΩ//100 pF loads, and exhibits low distortion (0.004% THD+N at 20 kHz, AV = 10) across its full operating temperature range. The device is characterized for both 5 V single-supply and ±5 V split-supply operation, with consistent noise, offset, and bandwidth performance across both configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V (supports wide-range split supplies and 4.4 V to 16 V single-supply operation) |
| Gain-Bandwidth Product | 2.25 MHz typ at ±5 V - enables stable closed-loop gain up to ~20 at 100 kHz |
| Slew Rate | 3.6 V/µs typ at ±5 V - supports 1 Vpp signals up to ~500 kHz without slew-induced distortion |
| Input Offset Voltage | 950 µV max at 25°C, 1500 µV max over −55°C to 125°C - ensures <0.1% error in 1 V full-scale precision gain stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277UA | Higher precision: 10 µV max VIO, 0.1 µV/°C drift; but only rated −40°C to 85°C, no extended temp option | Best for lab-grade instrumentation where ambient temperature is controlled; not suitable for under-hood or space environments | Select OPA2277UA only if offset and drift dominate requirements and extended temperature is unnecessary |
| TLC2272CDR | Same architecture and pinout, but commercial-grade (0°C to 70°C) and 2.5 mV max VIO - lower cost, no enhanced reliability testing | Acceptable for consumer or non-critical industrial use; lacks DMS support and HAST qualification | Choose TLC2272CDR for cost-sensitive volume production where extended temperature and long-term reliability are not required |
Compared with OPA2277UA and TLC2272CDR, the TLC2272AMDREPG4 uniquely balances extended-temperature operation, rail-to-rail output, low noise, and low input bias - making it the only option among the three qualified for aerospace, downhole, and military platforms requiring −55°C to 125°C continuous operation with JEDEC pedigree.

The TLC2272AMDREPG4 is fully specified and qualified for continuous operation from −55°C to 125°C. This extended temperature range is validated per JEDEC standards including Highly Accelerated Stress Test (HAST), temperature cycling, and electromigration testing - confirming suitability for aerospace, downhole, and military applications where ambient conditions exceed commercial-grade limits.
Does the TLC2272AMDREPG4 support single-supply operation?
Yes, the TLC2272AMDREPG4 is fully specified for single-supply operation from 4.4 V to 16 V. Its common-mode input voltage range includes the negative rail (VDD−), and its rail-to-rail output swing allows full utilization of the supply range - enabling direct interfacing with microcontroller ADCs and low-voltage logic without external level-shifting components.
What is the input offset voltage specification for the TLC2272AMDREPG4?
The TLC2272AMDREPG4 has a maximum input offset voltage of 950 µV at 25°C and 1500 µV across the full −55°C to 125°C operating range. This specification is guaranteed by TI's Enhanced Product (EP) qualification process and applies to the M-level (−55°C to 125°C) variant, ensuring predictable DC accuracy in precision gain stages and sensor interfaces.
Is the TLC2272AMDREPG4 pin-compatible with other devices in the TLC227x family?
Yes, the TLC2272AMDREPG4 uses the standard 8-pin SOIC (D) package and shares identical pinout with all TLC2272 variants including TLC2272CDR, TLC2272IDR, and TLC2272MDREP. This allows drop-in replacement within the same package footprint, though electrical specifications (e.g., offset voltage, temperature range) differ between grade levels.
What is the typical input voltage noise of the TLC2272AMDREPG4 and at what frequency is it measured?
The TLC2272AMDREPG4 has a typical input voltage noise of 9 nV/√Hz at 1 kHz, as confirmed in the official Texas Instruments datasheet SGLS131B. This value remains stable across the −55°C to 125°C range and is critical for preserving signal-to-noise ratio in low-amplitude sensor amplification, especially when paired with high-impedance sources such as piezoelectric transducers.
