Product details
Overview
TLC2274IPW from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for precision, low-noise signal conditioning in single- or split-supply systems. It delivers 2.2-MHz gain-bandwidth, 3.6-V/µs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1-pA typical input bias current, and rail-to-rail output swing - enabling high-fidelity interfacing with ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2274IPW datasheet, TLC2274IPW pinout, TLC2274IPW application, or TLC2274IPW equivalent, key selection criteria include its rail-to-rail output capability under ±5 V or 5-V supply, ultra-low input bias current for high-impedance transducer interfaces, guaranteed 950 µV max input offset voltage (A-grade), and TSSOP-14 package compatibility with space-constrained industrial monitoring designs.
Technical Context
The TLC2274IPW uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise - a combination not found in standard bipolar or older CMOS op-amps. Its input stage operates with common-mode range extending to the negative rail, supporting ground-referenced inputs in single-supply configurations.
It features unity-gain stable compensation, 50° phase margin, and 10 dB gain margin with 10-kΩ load and 100-pF capacitive load, ensuring robust stability in real-world PCB layouts. The device draws 4.8 mA typical supply current at ±5 V, balancing speed and power for portable instrumentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2444IDR | Lower supply current (1.3 mA/ch), but reduced GBW (1.8 MHz) and higher VIO (2 mV max) | Better suited for ultra-low-power, lower-precision portable devices where speed <1 MHz suffices | Select TLV2444IDR only when quiescent current is primary constraint and 2-mV offset is acceptable |
| OPA4340UA | Higher precision (125 µV VIO max), lower noise (8 nV/√Hz), but higher cost and 5.5-V max supply | Ideal for medical-grade analog front-ends requiring sub-0.01% linearity and low-frequency stability | Choose OPA4340UA when absolute DC accuracy and 0.1-Hz–10-Hz noise dominate over supply voltage flexibility |
Compared with TLV2444IDR, TLC2274IPW offers 2.25-MHz bandwidth and tighter 950-µV offset for medium-speed precision; versus OPA4340UA, it supports ±8-V supplies and costs significantly less, trading some DC precision for broader operating range and value.

FAQ
What supply voltage ranges does the TLC2274IPW support?
The TLC2274IPW supports single-supply operation from 4.4 V to 16 V or split-supply operation from ±2.2 V to ±8 V. At ±5 V, it delivers rail-to-rail output swing and 3.6-V/µs slew rate. The device is fully characterized across this range, including input common-mode range extending to VDD− and guaranteed performance at TA = –40°C to +125°C for I-grade parts.
Does the TLC2274IPW have rail-to-rail input capability?
No, the TLC2274IPW features rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends to the negative rail (VDD−) but stops 1.5 V below the positive rail (VDD+ −1.5 V) under recommended operating conditions. This allows ground-referenced inputs in single-supply systems but requires headroom at the top end for full-scale signal handling.
What is the maximum output current capability of the TLC2274IPW?
The TLC2274IPW can source or sink ±50 mA per channel, as specified in Absolute Maximum Ratings. However, for reliable operation within specifications, output current should be limited to ±5 mA to maintain VOL ≤ 1.5 V and VOH ≥ 4.25 V at TA = 25°C. Sustained ±20 mA loads require careful thermal management due to power dissipation limits in the TSSOP-14 package.
How does the TLC2274IPW compare to the TLC274 in terms of noise and offset voltage?
The TLC2274IPW improves on the TLC274 with 9 nV/√Hz input voltage noise (vs. 18 nV/√Hz typical for TLC274) and 950 µV maximum input offset voltage for the 'A' grade (vs. 5 mV max for TLC274). These enhancements enable higher signal fidelity in low-amplitude sensor applications and reduce calibration burden in precision DC measurement systems using the TLC2274IPW.
Is the TLC2274IPW pin-compatible with other quad op-amps in TSSOP-14 packages?
The TLC2274IPW follows the industry-standard TSSOP-14 pinout for quad op-amps (e.g., matching LM324, TLV2464, and OPA4340 pin assignments for inputs, outputs, and supplies). Pin 4 is VDD+, Pin 11 is VDD−, and Channels 1–4 follow sequential placement. However, electrical behavior (e.g., rail-to-rail output, input bias current) differs significantly - direct replacement requires validation of loop stability, noise, and DC error budgets in the target application.
