Product details
Overview
TLV2372IPG4 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 supports industrial temperature range (−40°C to +125°C) and is used in battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the TLV2372IPG4 datasheet, TLV2372IPG4 pinout, TLV2372IPG4 application, or TLV2372IPG4 equivalent, key selection criteria include rail-to-rail I/O swing, low 550 µA/channel quiescent current, shutdown mode (25 µA/channel), 39 nV/√Hz input noise, and 1 pA input bias current - critical for high-impedance, low-power analog front-ends.
Technical Context
The TLV2372IPG4 integrates two independent CMOS-input op-amps with rail-to-rail input stage (common-mode range from GND to VDD) and rail-to-rail output stage (swing within 150 mV of rails at 1 mA load). Its 3-MHz unity-gain bandwidth and 2.4 V/µs slew rate are maintained across 2.7–16 V supply, enabling stable operation in single-supply Li-ion (2.7–4.2 V) and wide-range industrial systems.
Shutdown functionality is implemented via dedicated active-low SHDN pins (pins 1 and 8), each controlling one amplifier independently. When asserted, supply current drops to 25 µA per channel while preserving input bias path integrity and enabling fast turnon/turnoff times (0.8 µs / 1 µs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell Li-ion, multi-cell alkaline, and ±1.35 V to ±8 V split supplies. |
| Bandwidth (UGBW) | 3 MHz - enables accurate amplification of signals up to ~300 kHz in closed-loop gain ≥10 configurations. |
| Slew Rate | 2.4 V/µs - ensures <1% distortion for 1-Vpp signals up to ~380 kHz in unity-gain follower. |
| Quiescent Current | 550 µA per channel - allows continuous operation in sub-1-mA system power budgets. |
| Input Bias Current | 1 pA - minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiodes). |
| Rail-to-Rail I/O | Input common-mode: 0 V to VDD; Output swing: within 150 mV of rails at 1 mA - maximizes dynamic range in low-voltage ADC driver stages. |
| Shutdown Current | 25 µA per channel - reduces total system standby power by >95% vs active mode. |
Pinout & Package
TLV2372IPG4 is packaged in an 8-pin PDIP (Plastic Dual In-line Package) with body size 9.81 mm × 6.35 mm. Pin 1 is identified by a molded dot or beveled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, Channel 1 | Analog output node for first op-amp; capable of sourcing/sinking ±5 mA near mid-rail. |
| GND | Ground Reference | Common return path for both amplifiers and supply; must be low-impedance for noise immunity. |
| 1IN+ | Noninverting Input, Ch1 | High-impedance (1 TΩ) positive input; accepts signals from 0 V to VDD without phase reversal. |
| VDD | Positive Supply | Single positive rail (2.7–16 V); no negative supply required for rail-to-rail operation. |
| 1IN− | Inverting Input, Ch1 | High-impedance (1 TΩ) negative input; used for feedback and signal inversion configurations. |
| 2IN− | Inverting Input, Ch2 | Independent high-Z input for second amplifier; electrically isolated from Channel 1. |
| 2OUT | Output, Channel 2 | Second independent output; fully specified for same AC/DC performance as Channel 1. |
| 2IN+ | Noninverting Input, Ch2 | Second noninverting input; supports differential or independent signal paths per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables full-scale signal acquisition from GND to VDD - eliminates level-shifting in single-supply sensor interfaces. |
| 3-MHz bandwidth at 550 µA | Delivers 10× higher speed-per-power than legacy TLC227x, enabling faster response in closed-loop control loops. |
| 1 pA input bias current | Reduces offset drift in high-Z transducer circuits (e.g., piezoelectric sensors), improving long-term measurement stability. |
| Independent shutdown per channel | Allows selective power gating of one amplifier while keeping the other active - essential for multi-function analog subsystems. |
| −40°C to +125°C operation | Qualified for industrial and automotive under-hood environments without derating or external thermal management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Same electrical specs, but in 8-pin SOIC (4.90 mm × 3.91 mm) instead of PDIP; lower RθJA (138.4°C/W vs 49.2°C/W). | SOIC package requires reflow-compatible PCB layout; better thermal performance in compact industrial modules. | Select TLV2372IDR for surface-mount production and improved power dissipation in space-constrained designs. |
| TLV2472CDR | Higher 600 µA/channel supply current, 2.8 MHz bandwidth, 1.5 V/µs slew rate, no shutdown; input bias 2 pA. | Lacks shutdown function and has reduced rail-to-rail output swing (within 200 mV of rails), limiting low-voltage ADC drive capability. | Choose TLV2472CDR only when shutdown is unnecessary and higher DC precision (150 µV VOS max) outweighs power and I/O swing trade-offs. |
Compared with TLV2372IPG4, TLV2372IDR offers identical performance in a smaller, surface-mount package ideal for automated assembly, while TLV2472CDR trades shutdown and rail-to-rail output for slightly better DC accuracy and lower input offset - making it suitable only where power gating and full output swing are not required.

FAQ
What is the maximum supply voltage for TLV2372IPG4?
The absolute maximum supply voltage for TLV2372IPG4 is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Exceeding 16 V risks permanent damage, and operation above 16 V is not guaranteed for parametric performance or reliability. The device supports split supplies (±1.35 V to ±8 V), making TLV2372IPG4 compatible with both single-ended and bipolar signal chains.
Does TLV2372IPG4 support true rail-to-rail output swing?
Yes, TLV2372IPG4 delivers rail-to-rail output swing: at 1 mA load, output voltage reaches within 150 mV of both VDD and GND across the full −40°C to +125°C temperature range. This enables direct interfacing with 3.3-V or 5-V ADC references without external level-shifting circuitry, preserving signal fidelity and reducing bill-of-materials count in TLV2372IPG4-based designs.
How does the shutdown feature work on TLV2372IPG4?
TLV2372IPG4 has no dedicated shutdown pin - unlike TLV2373 or TLV2375, the TLV2372IPG4 variant lacks integrated shutdown functionality. The "SHDN" designation in the family name applies only to specific members (TLV2370, TLV2373, TLV2375); TLV2372IPG4 operates continuously when powered. This is confirmed by the absence of SHDN pins in its 8-pin PDIP pinout and omission from all TLV2372-specific electrical characteristics tables in the datasheet.
What is the input bias current specification for TLV2372IPG4?
The input bias current for TLV2372IPG4 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 use with high-impedance sources such as photodiodes, pH electrodes, and capacitive sensors without significant signal attenuation or offset error - a key advantage of TLV2372IPG4 in precision analog front-ends.
Can TLV2372IPG4 drive a 10-kΩ load across the full temperature range?
Yes, TLV2372IPG4 maintains rail-to-rail output swing and specified AC performance driving a 10-kΩ load from −40°C to +125°C. At 25°C and VDD = 5 V, VOH = 4.9 V and VOL = 0.1 V into 10 kΩ; worst-case values at temperature extremes remain within 150 mV of rails. Slew rate (2.4 V/µs) and bandwidth (3 MHz) are also characterized under 10-kΩ load conditions, confirming TLV2372IPG4's suitability for buffered ADC driver and active filter applications.
