Texas Instruments TLV2372IP

Overview

TLV2372IP from Texas Instruments is a dual, rail-to-rail input and output operational amplifier with shutdown control, operating from 2.7 V to 16 V supply, delivering 3 MHz bandwidth and 2.4 V/µs slew rate at 550 µA per channel. It features 1 pA input bias current, 39 nV/√Hz input voltage noise, and −40°C to +125°C industrial temperature range - used in portable blood glucose systems and remote sensing interfaces.

For engineers reviewing the TLV2372IP datasheet, TLV2372IP pinout, TLV2372IP application, or TLV2372IP equivalent, key selection considerations include its dual-channel RRIO performance, low-power shutdown mode (25 µA/channel), SOIC-8 package compatibility, and suitability for single-supply sensor signal conditioning in battery-powered industrial and medical devices.

Technical Context

The TLV2372IP employs CMOS input stage enabling ultra-low input bias current (1 pA) and high-impedance sensor interfacing, while its rail-to-rail input common-mode range (0 V to VDD) and output swing (within 150 mV of rails at 1 mA load) support full dynamic range utilization in low-voltage systems. Its 3-MHz unity-gain bandwidth and 2.4 V/µs slew rate are maintained across 2.7–16 V supply range.

Shutdown functionality is implemented via dedicated active-low control pins per channel (pins 6 and 9 in SOIC-14 variants), but TLV2372IP (SOIC-8) lacks per-channel shutdown - it uses a shared shutdown pin (pin 8) enabling both amplifiers simultaneously. This simplifies control logic but eliminates independent channel power gating.

FAQ

What is the maximum supply voltage for TLV2372IP?

The absolute maximum supply voltage for TLV2372IP 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, the device delivers full 3-MHz bandwidth and 2.4 V/µs slew rate while maintaining rail-to-rail output swing within 200 mV of each rail at 1 mA load - verified across −40°C to +125°C.

Does TLV2372IP support true rail-to-rail input and output?

Yes, TLV2372IP supports rail-to-rail input (common-mode range from GND to VDD) and rail-to-rail output (swing within 150 mV of GND and VDD at 1 mA load). This is achieved via complementary input differential pairs and push-pull output stage - enabling direct interfacing with 3.3-V or 5-V ADCs without external level-shifting circuitry, as confirmed in the Electrical Characteristics table (VOH/VOL specifications).

How does the shutdown function work on TLV2372IP?

TLV2372IP features a single active-low shutdown pin (pin 8, labeled SHDN) that disables both amplifiers simultaneously. When pulled ≤0.8 V (relative to GND), supply current drops to 25 µA per channel and outputs enter high-impedance state. Leaving SHDN unconnected or tied to VDD keeps both channels active. Turnon/turnoff times are 0.8 µs and 1 µs respectively - fast enough for duty-cycled sensor acquisition in portable medical devices.

What is the input bias current specification for TLV2372IP?

The input bias current for TLV2372IP is 1 pA typical at 25°C, with a maximum of 60 pA over temperature (−40°C to +125°C). This ultra-low value results from its CMOS input stage and enables accurate amplification of signals from high-impedance sources such as pH electrodes, piezoelectric sensors, and photodiode transimpedance configurations - where even 100-pA bias would introduce significant offset errors.

Is TLV2372IP compatible with the TLC2272 in existing designs?

TLV2372IP is not a drop-in replacement for TLC2272 due to key differences: TLV2372IP adds shutdown capability (TLC2272 has none), operates down to 2.7 V (TLC2272 minimum is 4 V), and exhibits lower input bias current (1 pA vs 1 pA typical but 100 pA max for TLC2272). Pinout is identical in SOIC-8, but layout review is required to verify SHDN pin handling and bypass capacitor placement for stable low-voltage operation.
