Texas Instruments TLV274IPW

Overview

TLV274IPW from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-power, wide-bandwidth signal conditioning in battery-powered and industrial systems. It delivers 3-MHz unity-gain bandwidth, 2.4 V/µs slew rate, 550 µA/channel supply current, and 39 nV/√Hz input voltage noise across a 2.7 V to 16 V supply range - enabling precision sensing and analog front-end design in Li-ion–powered instrumentation and building automation.

For engineers reviewing the TLV274IPW datasheet, TLV274IPW pinout, TLV274IPW application, or TLV274IPW equivalent, key selection criteria include rail-to-rail output swing down to 100 mV from rails at 1 mA load, ultra-low 1 pA input bias current for high-impedance sensor interfaces, and guaranteed operation from –40°C to +125°C in the TSSOP-14 package.

Technical Context

The TLV274IPW employs a CMOS input stage and Class AB output stage to achieve rail-to-rail output swing while maintaining stable AC performance up to 3 MHz. Its input common-mode range extends from ground to VDD − 1.35 V, supporting single-supply operation with full dynamic range utilization.

It operates without shutdown functionality and features no internal ESD protection diodes on inputs - requiring external clamping for overvoltage conditions beyond absolute maximum ratings. Thermal resistance (RθJA) is 135°C/W in the PW (TSSOP-14) package, consistent with its 14-pin surface-mount footprint and 5.00 mm × 4.40 mm body size.

FAQ

What is the maximum capacitive load the TLV274IPW can drive without oscillation?

The TLV274IPW maintains stability with ≤10 pF capacitive load directly at the output. For larger loads (e.g., ADC input capacitance or long traces), TI recommends adding a series resistor (RNULL ≥20 Ω) between the TLV274IPW output and the load to preserve phase margin above 65°. This configuration prevents ringing in step responses and ensures reliable settling in precision acquisition systems using the TLV274IPW.

Does the TLV274IPW support true rail-to-rail input common-mode range?

No, the TLV274IPW does not support rail-to-rail input. Its input common-mode voltage range is specified from 0 V to VDD − 1.35 V - meaning it cannot accept signals within 1.35 V of the positive rail. However, the output swings rail-to-rail (within 100 mV of VDD and GND at 1 mA), making the TLV274IPW ideal for single-supply applications where output headroom is critical but input signals remain below VDD − 1.35 V.

Can the TLV274IPW operate from a 2.7-V single supply and still meet all AC specifications?

Yes, the TLV274IPW is fully specified at 2.7 V. At this minimum supply, it delivers 2.4 MHz unity-gain bandwidth (vs 3 MHz at 5 V), 1.35 V/µs slew rate (vs 2.4 V/µs), and maintains rail-to-rail output swing. All DC parameters - including input offset voltage (7 mV max), CMRR (55 dB min), and PSRR (65 dB min) - are guaranteed across the full temperature range at 2.7 V, ensuring robust performance in Li-ion–powered devices using the TLV274IPW.

Is the TLV274IPW pin-compatible with the TLC274?

No, the TLV274IPW is not pin-compatible with the TLC274. While both are quad op-amps in 14-pin packages, the TLC274 (SOIC-14) uses a different pinout: its VDD is Pin 4 and GND is Pin 11, whereas the TLV274IPW places VDD at Pin 4 and GND at Pin 11 - matching only in location, but functional compatibility requires verification. More critically, the TLC274 lacks rail-to-rail output and draws 675 µA/channel, so direct substitution with the TLV274IPW requires layout review and validation of output swing requirements.

What is the thermal resistance (RθJA) of the TLV274IPW in its TSSOP-14 package?

The TLV274IPW in the PW (TSSOP-14) package has a junction-to-ambient thermal resistance (RθJA) of 135°C/W, as specified in Section 7.5 of the datasheet. This value assumes standard JEDEC 2-layer board conditions. With a maximum junction temperature of 150°C and ambient of 85°C, the device supports up to 485 mW of total power dissipation (P = ΔT / RθJA). Derating is required above 85°C ambient, and proper copper pour under the exposed pad (if present) improves thermal performance - though the PW package lacks an exposed thermal pad.
