Product details
Overview
TLV2374IPW from Texas Instruments is a quad rail-to-rail input and output operational amplifier with shutdown capability, designed for low-power precision signal conditioning in battery-powered and industrial systems. It delivers 3-MHz bandwidth, 2.4 V/µs slew rate, 550 µA per channel supply current, and operates from 2.7 V to 16 V across −40°C to +125°C. It is used in portable medical devices, remote sensing front-ends, and active filter stages where rail-to-rail swing and low quiescent current are critical.
For engineers reviewing the TLV2374IPW datasheet, TLV2374IPW pinout, TLV2374IPW application, or TLV2374IPW equivalent, key selection criteria include its quad-channel TSSOP-14 package, shutdown control per channel pair, rail-to-rail I/O performance at 2.7-V operation, and verified 125°C industrial-grade thermal stability - all essential for space-constrained, wide-temperature embedded designs.
Technical Context
The TLV2374IPW integrates four independent CMOS-input op-amps sharing a single VDD and GND, with two dedicated shutdown pins (pins 1/2SHDN and 3/4SHDN) enabling independent power gating of channel pairs. Its rail-to-rail input stage uses complementary differential pairs, while the output stage employs Class AB push-pull architecture to achieve full-swing capability down to 2.7 V.
It supports single-supply operation from 2.7 V to 16 V (±1.35 V to ±8 V split), maintains 3-MHz unity-gain bandwidth and 65° phase margin with 100-pF capacitive load, and exhibits 1 pA input bias current and 39 nV/√Hz input voltage noise - characteristics optimized for high-impedance sensor interfacing and precision analog signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - enables direct interface with Li-ion batteries (3.0–4.2 V), 5-V logic rails, and 12-V industrial supplies without level-shifting. |
| Bandwidth (GBW) | 3 MHz - supports stable closed-loop gain up to ~300 at unity-gain compensated design for anti-aliasing and active filtering. |
| Slew Rate | 2.4 V/µs - ensures <2 µs settling for 1-V step response at 0.1% accuracy, suitable for medium-speed data acquisition. |
| Supply Current / Ch | 550 µA - allows four channels to operate below 2.2 mA total, extending battery life in handheld test equipment. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z sensor interfaces (e.g., pH electrodes, photodiode transimpedance amps). |
| Rail-to-Rail I/O | Full swing from VDD to GND - preserves dynamic range in low-voltage ADC driver and single-supply signal conditioning. |
| Shutdown Current | 25 µA per channel - reduces system standby power by >95% when unused channels are disabled via SHDN pins. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IPW | Higher supply current (550 µA → 725 µA/ch), wider GBW (6.4 MHz), no shutdown, rail-to-rail output only. | Lacks shutdown control and rail-to-rail input - unsuitable for low-voltage sensor buffering where common-mode range includes GND. | Choose TLV2464IPW only if higher speed and output swing are prioritized over power and input range. |
| TLV2784IPW | Lower supply current (550 µA → 400 µA/ch), lower bandwidth (2 MHz), no shutdown, rail-to-rail output only. | Missing rail-to-rail input and shutdown - cannot interface directly with 0-V referenced sensors or support dynamic power management. | Select TLV2784IPW only for cost-sensitive, non-critical applications where 2-MHz bandwidth and no shutdown are acceptable. |
Compared with TLV2464IPW and TLV2784IPW, the TLV2374IPW uniquely combines rail-to-rail input/output, per-pair shutdown, and 3-MHz bandwidth at 550 µA - making it the only option among the three qualified for precision, low-voltage, power-aware industrial and portable designs.

FAQ
What is the maximum operating supply voltage for TLV2374IPW?
The TLV2374IPW supports a maximum supply voltage of 16 V, verified per Absolute Maximum Ratings. Operation beyond this risks permanent damage. At 15 V, it delivers full 3-MHz bandwidth and 2.4 V/µs slew rate while maintaining rail-to-rail output swing - making it compatible with standard 12-V industrial rails and legacy ±8-V split supplies.
Does TLV2374IPW support true rail-to-rail input at 2.7 V supply?
Yes, TLV2374IPW guarantees rail-to-rail input operation from 0 V to VDD across its full −40°C to +125°C range, including at minimum 2.7-V supply. This is achieved via complementary input stage topology, enabling accurate amplification of ground-referenced sensor signals (e.g., thermocouples, strain gauges) without level-shifting circuitry.
How does the shutdown function work on TLV2374IPW?
TLV2374IPW features two independent active-low shutdown pins: pin 8 (1/2SHDN) disables channels 1 and 2, and pin 9 (3/4SHDN) disables channels 3 and 4. Driving either pin ≤0.8 V reduces supply current per affected channel to 25 µA. Pins can be left floating (default enabled) or tied to VDD via pull-up for controlled disable.
What is the typical input offset voltage of TLV2374IPW at 25°C?
The typical input offset voltage of TLV2374IPW at 25°C is 4.5 mV, with a maximum of 6 mV over the full −40°C to +125°C range. This value is measured with VDD = 2.7–15 V, common-mode input at VDD/2, and output at VDD/2 - ensuring predictability in precision DC-coupled applications like sensor signal conditioning.
Is TLV2374IPW pin-compatible with other TSSOP-14 quad op-amps?
No, TLV2374IPW is not pin-compatible with generic TSSOP-14 quad op-amps due to its unique dual shutdown pin assignment (pins 8 and 9). Standard quad op-amps (e.g., LM324, TLV2464) use those pins for NC or additional power terminals. Direct replacement requires PCB layout revision to accommodate the TLV2374IPW's specific pinout and shutdown logic.
