Product details
Overview
TLV2372QDRQ1 from Texas Instruments is a dual-channel, rail-to-rail input and output automotive-grade operational amplifier designed for precision signal conditioning in engine control units and battery management systems. It delivers 3 MHz gain-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 ambient temperature.
For engineers reviewing the TLV2372QDRQ1 datasheet, TLV2372QDRQ1 pinout, TLV2372QDRQ1 application, or TLV2372QDRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, ultra-low 1 pA input bias current, 39 nV/√Hz input voltage noise, and SOIC-8 package compatibility with high-voltage start-stop automotive power rails.
Technical Context
The TLV2372QDRQ1 uses CMOS input stage architecture enabling femtoampere-level input bias current and rail-to-rail common-mode input range up to the positive supply rail. Its unity-gain stable design supports direct sensing of differential voltages across shunt resistors without phase reversal, even when inputs approach VDD.
Internal Class AB output stage provides symmetrical rail-to-rail output swing with low output impedance (typ. 100 Ω), supporting drive into 2 kΩ loads while maintaining <0.1% settling in 2 µs at AV = –1. The device lacks shutdown functionality and relies on supply voltage control for power management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2272QDRQ1 | Lower bandwidth (2.2 MHz), higher supply current (1100 µA/ch), rail-to-rail output only | Less suitable for high-frequency current sensing; better for low-noise DC-coupled sensor buffering | Choose when lower cost and higher output drive capability outweigh bandwidth and quiescent current requirements |
| TLV2462IDR | Includes shutdown pin, wider GBW (6.4 MHz), but limited to 2.7–6 V supply and non-automotive qualification | Not qualified for automotive temperature range; requires external voltage regulation for 12-V systems | Choose for industrial or consumer designs needing shutdown control and higher speed, not for automotive deployment |
Compared with TLC2272QDRQ1 and TLV2462IDR, TLV2372QDRQ1 uniquely balances AEC-Q100 Grade 1 compliance, 3-MHz bandwidth, rail-to-rail I/O, and 550-µA/channel quiescent current-making it optimal for space-constrained, battery-sensitive automotive signal chains where reliability across temperature extremes is mandatory.

FAQ
What automotive qualification does TLV2372QDRQ1 meet?
TLV2372QDRQ1 meets AEC-Q100 Grade 1 qualification, certified for ambient operating temperatures from –40°C to +125°C, HBM ESD level 2 (±2000 V), and CDM ESD level C4B (±500 V). This makes TLV2372QDRQ1 suitable for use in engine control units, body control modules, and other safety-critical automotive subsystems where reliability under thermal stress is essential.
Does TLV2372QDRQ1 support rail-to-rail input and output?
Yes, TLV2372QDRQ1 supports true rail-to-rail input and output operation. Its CMOS input stage allows common-mode voltage range from 0 V to VDD, and its Class AB output stage delivers output swing within 10 mV of both supply rails under 1-mA load. This capability is confirmed in the Electrical Characteristics table and functional description of TLV2372QDRQ1.
What is the maximum supply voltage for TLV2372QDRQ1?
The absolute maximum supply voltage for TLV2372QDRQ1 is 16.5 V, with recommended operation from 2.7 V to 16 V. This wide range enables direct connection to 12-V automotive batteries-including transient spikes during load dump-and supports start-stop functionality without external regulators. Data sheet Section 7.1 confirms this rating for TLV2372QDRQ1.
Is TLV2372QDRQ1 pin-compatible with other devices in the TLV237x-Q1 family?
TLV2372QDRQ1 shares identical pinout with TLV2371-Q1 and TLV2374-Q1 in SOIC packages, but differs in channel count: TLV2372QDRQ1 is dual-channel (8-pin), TLV2371-Q1 is single-channel (8-pin SOIC or 5-pin SOT-23), and TLV2374-Q1 is quad-channel (14-pin). Pin functions for shared pins (e.g., GND, VDD, IN+, IN–, OUT) match across the family, enabling layout reuse where channel count permits.
What is the input bias current specification for TLV2372QDRQ1?
TLV2372QDRQ1 has a typical input bias current of 1 pA at 25°C, with a maximum of 500 pA over the full –40°C to +125°C temperature range. This ultra-low value is enabled by its CMOS input stage and is critical for minimizing offset errors in high-impedance applications such as thermistor-based temperature sensing or precision voltage dividers used in TLV2372QDRQ1-based BMS designs.
