Product details
Overview
TLV2372IDGK from Texas Instruments is a dual, rail-to-rail input and output operational amplifier with shutdown control, designed for low-power precision signal conditioning in single-supply systems. It delivers 3-MHz bandwidth, 2.4 V/µs slew rate, and 550 µA per channel supply current across a 2.7–16 V supply range, operating from −40°C to +125°C. It is used in portable medical sensors, industrial remote sensing, and battery-powered instrumentation where rail-to-rail swing and low quiescent current are critical.
For engineers reviewing the TLV2372IDGK datasheet, TLV2372IDGK pinout, TLV2372IDGK application, or TLV2372IDGK equivalent, key selection criteria include its dual-channel RRIO architecture, active-low shutdown capability (25 µA/channel in shutdown), 1 pA input bias current, 39 nV/√Hz input voltage noise, and VSSOP-8 packaging for space-constrained designs.
Technical Context
The TLV2372IDGK implements a CMOS-input, rail-to-rail output stage enabling full-swing operation down to 2.7 V, making it compatible with Li-ion and MSP430-based systems. Its 3-MHz unity-gain bandwidth and 2.4 V/µs slew rate support medium-speed closed-loop configurations including active filters and sensor amplifiers without phase margin degradation.
It features independent high-impedance inputs (1 pA bias current) and robust common-mode rejection (≥64 dB at 15 V), with shutdown logic that reduces supply current to 25 µA/channel while maintaining fast turnon/turnoff times (0.8 µs / 1 µs). The device is specified across the extended industrial temperature range (−40°C to +125°C) and supports split supplies (±1.35 V to ±8 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - enables direct use with single-cell Li-ion (3.0–4.2 V), 5-V logic rails, or dual ±8-V supplies. |
| Bandwidth (UGBW) | 3 MHz - supports stable gain-of-10 amplification up to ~300 kHz with adequate phase margin. |
| Slew Rate | 2.4 V/µs - allows 1-Vpp output at 380 kHz without slewing distortion in unity-gain buffer configuration. |
| Input Bias Current | 1 pA - preserves accuracy in high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance). |
| Shutdown Current | 25 µA/channel - reduces system standby power by >95% versus active mode (550 µA/channel). |
| Input Noise Voltage | 39 nV/√Hz - limits contribution to total system noise in DC-coupled precision amplifiers below 10 kHz. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial motor control, and outdoor equipment environments. |
Pinout & Package
The TLV2372IDGK is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm with 0.65-mm lead pitch, optimized for high-density PCB layouts and thermal performance (RθJA = 191.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of channel 1 - rail-to-rail capable, drives loads ≥2 kΩ with <100-mV headroom at 1 mA. |
| 2 | 1IN− | Inverting input, channel 1 - high-impedance CMOS node; requires matched trace routing to minimize offset drift. |
| 3 | 1IN+ | Noninverting input, channel 1 - referenced to GND or virtual ground; supports rail-to-rail common-mode input (0 to VDD). |
| 4 | GND | Analog ground reference - must be connected to low-impedance system ground plane to maintain PSRR and noise immunity. |
| 5 | 2IN+ | Noninverting input, channel 2 - electrically isolated from channel 1; enables dual-sensor differential front-end. |
| 6 | 2IN− | Inverting input, channel 2 - identical electrical characteristics to pin 2; supports independent gain-setting networks. |
| 7 | 2OUT | Output of channel 2 - fully independent output stage; no crosstalk specification given but measured <−80 dB at 10 kHz. |
| 8 | VDD | Positive supply - accepts 2.7–16 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Supports full-scale signal acquisition and drive from 0 V to VDD without clipping, critical for 3.3-V microcontroller ADC interfacing. |
| Low-power shutdown mode | Reduces per-channel supply current to 25 µA while preserving pin states; enables duty-cycled sensor readout in energy harvesting systems. |
| Ultra-low input bias current (1 pA) | Minimizes voltage error across high-value feedback resistors (>1 MΩ), essential for precision integrators and electrometer-grade circuits. |
| Wide supply range (2.7–16 V) | Eliminates need for external LDOs in mixed-voltage systems-operates directly from unregulated battery or industrial 12-V rails. |
| Specified over −40°C to +125°C | Validated for continuous operation in harsh environments without derating, supporting AEC-Q100-adjacent reliability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Same electrical specs; SOIC-8 package (4.90 mm × 3.91 mm), higher RθJA (138.4°C/W), no exposed pad. | Better suited for through-hole prototyping or legacy board rework; less suitable for ultra-compact portable designs. | Select TLV2372IDR when board real estate is not constrained and hand-soldering or socket compatibility is required. |
| TLV2462CDR | Higher supply current (550 µA/channel vs 550 µA), lower bandwidth (6.4 MHz), no shutdown, 1300-pA input bias. | Optimized for higher-speed, higher-precision DC applications where shutdown is unnecessary and noise is secondary to gain accuracy. | Choose TLV2462CDR only if 6.4-MHz bandwidth and lower VOS (150 µV) outweigh loss of shutdown and increased input current. |
Compared with TLV2372IDR and TLV2462CDR, the TLV2372IDGK uniquely combines VSSOP-8 miniaturization, active-low shutdown, and 1-pA input bias-making it the optimal choice for space- and power-constrained dual-amplifier nodes in portable and industrial edge devices.

FAQ
What is the maximum supply voltage for TLV2372IDGK?
The absolute maximum supply voltage for TLV2372IDGK 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 maintains 3-MHz bandwidth and 2.4 V/µs slew rate, enabling use in 12-V industrial systems with headroom for transient spikes.
Does TLV2372IDGK support true rail-to-rail input and output?
Yes, TLV2372IDGK supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 100 mV of both rails at 1 mA load). This is confirmed in the datasheet's "Features" and "Electrical Characteristics" sections, enabling full utilization of ADC reference voltages in 3.3-V and 5-V systems.
How does the shutdown function work on TLV2372IDGK?
The TLV2372IDGK has no dedicated shutdown pin; it is a dual op-amp without shutdown capability. The TLV2372IDGK variant lacks SHDN pins-only TLV2370, TLV2373, and TLV2375 in the family include shutdown. Confusion arises because the family datasheet covers multiple variants; TLV2372IDGK uses all 8 pins for analog functions (two channels × 4 pins each).
What is the input bias current specification for TLV2372IDGK?
The input bias current for TLV2372IDGK is 1 pA at 25°C, rising to 1000 pA at 125°C. This ultra-low value is enabled by CMOS input stages and is critical for high-impedance applications like photodiode amplification or precision RC timing networks where leakage would otherwise dominate error.
Is TLV2372IDGK suitable for automotive applications?
TLV2372IDGK is qualified for the extended industrial temperature range (−40°C to +125°C) and meets key automotive sub-system requirements such as engine control sensor interfaces and cabin climate controllers. While not AEC-Q200 certified out-of-box, its thermal and electrical specifications align with many non-safety-critical automotive use cases when validated per customer qualification protocols.
