Product details
Overview
TLC2272AMDREP 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 TLC2272AMDREP datasheet, TLC2272AMDREP pinout, TLC2272AMDREP application, or TLC2272AMDREP equivalent, key selection criteria include its −55°C to 125°C operating range, rail-to-rail output swing with ±2.2 V to ±8 V supply support, low 2.4–3 mA supply current per amplifier, and compatibility with single- or split-supply configurations in space-constrained analog front-ends.
Technical Context
The TLC2272AMDREP uses Advanced LinCMOS™ process technology to achieve high input impedance (>1012 Ω), low input bias current (1 pA typ), and rail-to-rail output stage operation that swings within 15 mV of either supply rail under light load. Its internal architecture supports stable unity-gain operation with 50° phase margin and 10 dB gain margin when driving 10 kΩ || 100 pF loads.
It is fully characterized across −55°C to 125°C with guaranteed specifications including 75 dB common-mode rejection ratio (CMRR), 95 dB supply-voltage rejection ratio (SVR), and 20 V/mV large-signal differential voltage amplification at ±5 V supplies - making it suitable for high-reliability measurement systems where thermal drift and power supply variation must be minimized.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277UA | Higher precision (10 µV VIO max), bipolar input (2 nA IIB), ±2 V to ±18 V supply, no rail-to-rail output | Better DC accuracy but incompatible with rail-to-rail ADC drivers; requires higher supply headroom | Select when ultra-low offset drift (<0.1 µV/°C) outweighs output swing constraints |
| LMV722MMX/NOPB | Lower voltage (2.7–5.5 V), CMOS input (1 fA IIB), 10 MHz GBW, rail-to-rail I/O, −40°C to 125°C | Not qualified for −55°C operation; lacks extended-temp reliability testing and DMS pedigree | Select for commercial-grade portable instruments where cost and speed dominate over extreme environment assurance |
Compared with OPA2277UA and LMV722MMX/NOPB, the TLC2272AMDREP uniquely balances rail-to-rail output capability, −55°C to 125°C qualification, and 1 pA input bias current - making it the only option among the three validated for dual-role use in both sensor front-end and ADC interface stages of mission-critical aerospace systems.

FAQ
What is the maximum operating temperature range for the TLC2272AMDREP?
The TLC2272AMDREP is rated for continuous operation from −55°C to 125°C. This extended temperature range is verified per JEDEC JESD22-A108 with Highly Accelerated Stress Test (HAST), temperature cycling, and electromigration testing - confirming suitability for aerospace, downhole, and military platforms where ambient extremes are routine.
Does the TLC2272AMDREP support single-supply operation?
Yes, the TLC2272AMDREP is fully specified for single-supply operation. With common-mode input voltage range extending to the negative rail (VDD−) and rail-to-rail output swing, it operates reliably from 4.4 V to 16 V total supply (e.g., 0 V and +5 V, or 0 V and +12 V). Input and output performance parameters are guaranteed across this configuration per the datasheet's recommended operating conditions.
What is the input offset voltage specification for the TLC2272AMDREP at full temperature range?
The TLC2272AMDREP has a maximum input offset voltage of 1500 µV across the full −55°C to 125°C operating range. At 25°C, the limit is tighter: 950 µV max. The temperature coefficient is 2 µV/°C, meaning drift contributes predictably to total error - enabling accurate system-level calibration over temperature.
Is the TLC2272AMDREP pin-compatible with the standard TLC2272 series?
Yes, the TLC2272AMDREP uses the same 8-pin SOIC (D) package and identical pinout as the commercial TLC2272, including 1OUT, 1IN−, 1IN+, VDD−/GND, VDD+, 2OUT, 2IN−, and 2IN+. No PCB layout changes are required when upgrading from commercial-grade TLC2272 to the enhanced-product (EP) version for extended-temperature or high-reliability deployments.
How does the noise performance of the TLC2272AMDREP compare to the TLC272?
The TLC2272AMDREP delivers 9 nV/√Hz input voltage noise at 1 kHz - exactly half the 18 nV/√Hz typical noise of the TLC272. This 6 dB improvement directly enhances signal-to-noise ratio in low-level sensor amplification, especially critical for piezoelectric and capacitive transducers where source impedances exceed 1 MΩ. The TLC2272AMDREP also adds lower input offset voltage and rail-to-rail output not present in the TLC272.
