Product details
Overview
TLC2272ACP 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 handheld monitoring systems.
For engineers reviewing the TLC2272ACP datasheet, TLC2272ACP pinout, TLC2272ACP application, or TLC2272ACP 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 VDD−, and full characterization across ±2.2 V to ±8 V supplies.
Technical Context
The TLC2272ACP uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low noise and micropower operation. Its input stage supports common-mode voltages down to the negative rail, and its unity-gain-stable architecture enables direct use in single-supply sensor interfaces without level-shifting circuitry.
It operates over ±2.2 V to ±8 V supply ranges with 2.4 mA typical supply current per amplifier, and exhibits 75 dB minimum CMRR and 80 dB minimum PSRR - making it suitable for transducer amplification where supply rejection and interference immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.25 MHz - supports stable closed-loop operation up to ~200 kHz at AV = 10 |
| Slew rate | 3.6 V/µs - enables clean 20-kHz sine-wave output at 2.3-V peak without distortion |
| Input offset voltage | ≤950 µV (max, TA = 25°C) - ensures ≤0.02% error in 5-V full-scale instrumentation |

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 |
|---|---|---|---|
| TLC2272CDR | Same electrical specs; SOIC-8 package with Pb-free finish and tape-and-reel packaging | Identical functional behavior; optimized for automated SMT assembly | Select when RoHS compliance and volume production logistics are required |
| TLV2432IDR | Higher output drive (±25 mA vs ±50 mA), wider input voltage range (VDD− to VDD+ − 0.1 V), but higher supply current (1.2 mA/ch) | Better suited for driving capacitive loads or low-impedance DAC buffers | Choose for applications needing stronger output stage or extended input common-mode range |
Compared with TLC2272CDR, the TLC2272ACP offers identical AC/DC performance in a standard SOIC-8 but with legacy plating; versus TLV2432IDR, it trades output drive and input range for lower noise and bias current - favoring high-impedance, low-power sensor interfaces.

FAQ
What is the maximum supply voltage rating for the TLC2272ACP?
The TLC2272ACP has an absolute maximum supply voltage rating of ±8 V. Operation beyond this limit risks permanent damage. Recommended operating range is ±2.2 V to ±8 V, with full electrical specifications guaranteed across that span. The device is commonly used at ±5 V or +5 V single-supply configurations, and its rail-to-rail output remains functional even at the minimum ±2.2 V supply.
Does the TLC2272ACP support single-supply operation?
Yes, the TLC2272ACP is fully specified for single-supply operation. When powered from +5 V with VDD−/GND tied to 0 V, its common-mode input range extends to the negative rail (0 V), and its output swings rail-to-rail - from near 0 V to near 5 V. This eliminates the need for level-shifting circuitry when interfacing with microcontrollers or ADCs referenced to the same ground.
What is the input offset voltage specification for the TLC2272ACP?
The TLC2272ACP is the "A" grade variant, specifying a maximum input offset voltage of 950 µV at TA = 25°C and 1500 µV across the full operating temperature range (0°C to 70°C). This is tighter than the standard TLC2272 (2500 µV max at 25°C), making it suitable for precision DC-coupled applications such as strain gauge amplifiers or reference buffers where offset-induced errors must be minimized.
Can the TLC2272ACP drive capacitive loads directly?
The TLC2272ACP is unity-gain stable and characterized with 100-pF capacitive load in typical test conditions. However, driving >100-pF loads may degrade phase margin and cause ringing or oscillation. For loads exceeding 100 pF - such as long PCB traces or ADC input capacitance - a small isolation resistor (10–50 Ω) between the TLC2272ACP output and the capacitive load is recommended to maintain stability without compromising bandwidth.
Is the TLC2272ACP pin-compatible with the TLC272?
Yes, the TLC2272ACP is pin-compatible with the TLC272 in the same SOIC-8 package. Both share identical pinout: 1OUT, 1IN−, 1IN+, VDD−/GND, VDD+, 2IN−, 2IN+, and 2OUT. This allows direct replacement in existing designs to improve noise (9 nV/√Hz vs 25 nV/√Hz), input bias current (1 pA vs 100 pA), and output swing - without PCB or schematic changes.
