Texas Instruments TLV2374IN

Overview

TLV2374IN from Texas Instruments is a quad rail-to-rail input and output operational amplifier optimized for low-power, single-supply operation across 2.7 V to 16 V. It delivers 3 MHz unity-gain bandwidth, 2.4 V/µs slew rate, and 550 µA per channel supply current, with shutdown capability reducing current to 25 µA/channel. It serves in battery-powered sensor signal conditioning, portable medical devices, and industrial analog front-ends.

For engineers reviewing the TLV2374IN datasheet, TLV2374IN pinout, TLV2374IN application, or TLV2374IN equivalent, key selection criteria include its rail-to-rail I/O swing at low voltage, shutdown control timing (0.8 µs turnon), thermal performance in SOIC-14 (R_θJA = 67 °C/W), and compatibility with Li-ion and MSP430-based systems.

Technical Context

The TLV2374IN uses CMOS input stages enabling 1 pA input bias current and high-impedance sensor interfacing. Its rail-to-rail input stage supports common-mode voltages from GND to V_DD, while rail-to-rail output delivers >95% of full supply swing under 1 mA load.

It features independent internal shutdown logic per channel pair (pins 6 and 9), with active-low control and 0.8 µs enable time. The device operates across −40°C to +125°C and maintains 3 MHz bandwidth and 65° phase margin into 100 pF capacitive loads.

FAQ

What is the maximum supply voltage for TLV2374IN?

The absolute maximum supply voltage for TLV2374IN is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage. At 16 V, output swing remains rail-to-rail (within 100 mV of rails at 1 mA), and input common-mode range extends fully from GND to V_DD. Thermal derating applies above 70°C ambient due to R_θJA = 67 °C/W in SOIC-14.

Does TLV2374IN support true rail-to-rail input and output?

Yes, TLV2374IN supports true rail-to-rail input (common-mode range from GND to V_DD) and rail-to-rail output (typical swing within 100 mV of each rail at 1 mA load). This is confirmed across all four channels and over the full −40°C to +125°C temperature range. Output drive capability is symmetric: 4 mA source / 5 mA sink at 2.7 V, scaling to 16 mA source / 15 mA sink at 15 V.

How does the shutdown function work on TLV2374IN?

TLV2374IN does not include individual channel shutdown pins. Instead, it uses a dual-pair architecture: pins 6 and 9 serve as 1/2SHDN and 3/4SHDN, respectively - active-low controls that disable channels 1&2 or 3&4 simultaneously. When pulled low (<0.8 V), supply current per enabled channel drops from 550 µA to 25 µA. Turnon time is 0.8 µs; turnoff is 1 µs. Pins left floating default to active mode.

What is the input offset voltage specification for TLV2374IN?

The input offset voltage (V_OS) for TLV2374IN is 4.5 mV typical and 6 mV maximum over the full −40°C to +125°C temperature range. At 25°C, V_OS is 2–4.5 mV. Offset drift is 2 µV/°C typical. These values apply per channel and are measured with V_DD = 2.7–15 V, R_S = 50 Ω, and output at V_DD/2 - critical for precision DC amplification where <10 mV error is acceptable.

Can TLV2374IN drive capacitive loads?

TLV2374IN is stable driving up to 100 pF capacitive load with 65° phase margin (tested with R_L = 2 kΩ). For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain stability. The device's unity-gain bandwidth decreases slightly with increasing capacitive load - from 3 MHz at 10 pF to ~2.2 MHz at 100 pF - but remains functional for most sensor buffering and filter applications.
