Texas Instruments TLC2274AIPW

Overview

TLC2274AIPW from Texas Instruments is a quad rail-to-rail output operational amplifier in TSSOP-14 package, featuring 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 ±5-V operation with rail-to-rail output swing. It enables high-precision signal conditioning in battery-powered transducer interfaces and single-supply ADC driver stages.

For engineers reviewing the TLC2274AIPW datasheet, TLC2274AIPW pinout, TLC2274AIPW application, or TLC2274AIPW equivalent, key selection criteria include guaranteed 950-µV max input offset voltage (A-grade), rail-to-rail output capability down to GND, low-noise performance for high-impedance sources, and compatibility with 2.2-V to 16-V single or ±2.2-V to ±8-V dual supplies.

Technical Context

The TLC2274AIPW uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low noise (9 nV/√Hz). Its input stage operates with common-mode range extending to the negative rail, supporting true single-supply operation.

It delivers 2.2-MHz unity-gain bandwidth and 3.6-V/µs slew rate under ±5-V supply, with 75-dB minimum CMRR and 80-dB minimum PSRR across temperature. The device is fully specified for both single- and split-supply configurations, with maximum input offset voltage tightly binned to 950 µV at 25°C.

FAQ

What is the maximum input offset voltage specification for TLC2274AIPW?

The TLC2274AIPW has a maximum input offset voltage of 950 µV at TA = 25°C, as defined by its "A" grade designation. This value increases to 1500 µV across the full operating temperature range (–40°C to 125°C for I/Q-grade versions). The tighter VIO bin enables high-accuracy DC amplification without external nulling circuitry in applications like sensor signal conditioning and precision reference buffering.

Does TLC2274AIPW support true single-supply operation with input signals down to ground?

Yes, the TLC2274AIPW supports true single-supply operation: its common-mode input voltage range extends to VDD− (i.e., ground in single-supply mode), and its output swings rail-to-rail. When powered from a 5-V supply (VDD+ = 5 V, VDD− = GND), inputs can be as low as 0 V, and outputs reach within 10 mV of both 0 V and 5 V under light load-making it suitable for interfacing directly with microcontroller ADCs and digital logic.

What is the typical supply current for TLC2274AIPW at ±5 V operation?

At ±5 V dual supply and TA = 25°C, the TLC2274AIPW draws 4.8 mA typical supply current (IDD), with a maximum of 6 mA across temperature and process variation. This equates to approximately 1.2 mA per amplifier channel, placing it between micropower and general-purpose op-amps-ideal for systems needing better AC performance than sub-100-µA devices without excessive power overhead.

Can TLC2274AIPW drive capacitive loads without instability?

The TLC2274AIPW is unity-gain stable into 100-pF capacitive loads with 10-kΩ series resistance, as verified in the datasheet's typical characteristics (phase margin ≥50°, gain margin ≥10 dB). For direct capacitive loads >100 pF, a small isolation resistor (e.g., 10–50 Ω) in series with the output is recommended. It is not optimized for heavy capacitive loads like LCD drivers or long cables without external compensation.

Is TLC2274AIPW pin-compatible with other devices in the TLC227x family?

Yes, the TLC2274AIPW is pin-compatible with all TLC2274-x variants in the TSSOP-14 package (e.g., TLC2274IPW, TLC2274MIPW), sharing identical pinout, footprint, and basic electrical behavior. Differences lie in grading (A-grade vs. standard), temperature range (I-grade –40°C to 125°C), and qualification level (automotive Q-temp). No PCB redesign is needed when upgrading from TLC2274IPW to TLC2274AIPW.
