Product details

Overview

TLV274CPWRG4 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 per channel supply current, 39 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V across –40°C to 125°C. It is used in smoke detectors and solar inverters where precision, low quiescent power, and rail-to-rail swing are critical.

For engineers reviewing the TLV274CPWRG4 datasheet, TLV274CPWRG4 pinout, TLV274CPWRG4 application, or TLV274CPWRG4 equivalent, key selection considerations include guaranteed rail-to-rail output swing at 2.7 V, ultra-low 1 pA input bias current for high-impedance sensor interfaces, thermal performance in TSSOP-14 (R_θJA = 135°C/W), and compatibility with Li-ion and MSP430-based systems.

Technical Context

The TLV274CPWRG4 uses CMOS input stage architecture enabling 1 pA typical input bias current and rail-to-rail output swing down to within 135 mV of each rail under 1 mA load. Its 3-MHz gain-bandwidth product and 2.4 V/µs slew rate support stable closed-loop operation up to 50 kHz in second-order filter designs.

It is fully specified for single-supply (2.7–16 V) and split-supply (±1.35 V to ±8 V) operation, with common-mode input range extending from ground to V_DD – 1.35 V. Input offset voltage is 5 mV (typ), and PSRR is 80 dB (typ) - enabling robust performance in noisy power environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Bandwidth	3 MHz unity-gain bandwidth enables stable amplification of signals up to ~50 kHz in filter and sensor interface applications.
Slew Rate	2.4 V/µs supports fast transient response in battery monitor circuits without distortion at 3-V supply.

Equivalent & Alternatives

The following parts are listed as comparable options for similar operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV274IPWR	Same electrical specs, but rated for –40°C to +125°C (I-suffix) vs C-suffix (0°C to 70°C) in TLV274CPWRG4.	Required for automotive under-hood or outdoor industrial deployments where extended temperature is mandatory.	Select TLV274IPWR when operating ambient exceeds 70°C or when long-term reliability at temperature extremes is required.
TLV2374IPWR	Includes shutdown mode (active-low EN pin), 550 µA/ch quiescent current, same 3-MHz GBW, but input common-mode range includes V_DD (rail-to-rail input).	Preferred in power-bank designs requiring periodic deep-sleep modes to extend standby time beyond 30 days.	Choose TLV2374IPWR only if system-level power sequencing or shutdown control is needed - adds complexity but reduces idle current to <100 nA.

Compared with TLV274CPWRG4, TLV274IPWR offers identical performance with extended temperature qualification, while TLV2374IPWR trades off shutdown capability and rail-to-rail input for slightly higher cost and layout overhead - neither is pin-compatible, but both share the same TSSOP-14 footprint.

FAQ

What is the maximum supply voltage for TLV274CPWRG4?

The absolute maximum supply voltage for TLV274CPWRG4 is 16.5 V, but the recommended maximum operating voltage is 16 V. Operation above 16 V risks permanent damage. The device is fully specified from 2.7 V to 16 V, supporting single-supply use with Li-ion cells (2.7–4.2 V) and dual-supply configurations up to ±8 V. Always observe derating guidelines in TI's SLOS351E datasheet Section 7.1.

Does TLV274CPWRG4 support rail-to-rail input?

No, TLV274CPWRG4 does not support rail-to-rail input. Its common-mode input voltage range is specified from 0 V to V_DD – 1.35 V. For example, at 5 V supply, inputs must stay between 0 V and 3.65 V. This differs from rail-to-rail input op-amps like TLV2374. TLV274CPWRG4 does provide true rail-to-rail output swing, delivering VOH ≥ 4.9 V and VOL ≤ 0.1 V at 5 V/1 mA load.

What is the thermal resistance (R_θJA) of TLV274CPWRG4 in its TSSOP-14 package?

The junction-to-ambient thermal resistance (R_θJA) for TLV274CPWRG4 in the PW (TSSOP-14) package is 135°C/W, as documented in Section 7.5 of the SLOS351E datasheet. This value assumes standard JEDEC 2-layer board conditions. Actual thermal performance improves with additional copper area, internal planes, or thermal vias - design guidance is provided in TI's Layout Guidelines (Section 11.1).

Can TLV274CPWRG4 drive capacitive loads directly?

TLV274CPWRG4 can drive ≤10 pF capacitive loads stably without external compensation. For loads >10 pF - such as ADC input capacitance or long PCB traces - TI recommends adding a series resistor (R_NULL ≥ 20 Ω) between the op-amp output and the load to maintain phase margin >65° and prevent oscillation. This is detailed in Section 8.3.3 and Figure 26 of the SLOS351E datasheet.

Is TLV274CPWRG4 pin-compatible with other TLV27x variants?

TLV274CPWRG4 is pin-compatible with all TLV274 variants in the same TSSOP-14 (PW) package, including TLV274IPWR and TLV274CDR. However, it is not pin-compatible with TLV272 (8-pin) or TLV271 (5-pin or 8-pin) due to differing channel count and pin count. Always verify package suffix (PW) and temperature grade (C vs I) before substitution.
