TLV2371-Q1 - Automotive 550-uA/Ch 3-MHz Rail-to-Rail Input/Output Operational Amplifiers

Updated : 2020-01-09 14:20:27
Description

The TLV237x-Q1 devices are single-supply operational amplifiers providing rail-to-rail input and output capability. The TLV237x-Q1 takes the minimum operating supply voltage down to 2.7 V and up to 16 V over the extended automotive temperature range. Therefore, the wide voltage range can support both start-stop functionality and a connection directly to the typical 12-V battery. The rail-to-rail capabilities allow the device to maximize the output signal and avoid clipping.

The CMOS inputs enable high-impedance suitable for engine control units (ECU), body control modules (BCM), battery management systems (BMS), and HEV/EV inverters. This also allows the user to draw a lower offset voltage and maintain low power consumption to help meet overall system needs for quiescent current such as in infotainment or cluster, HEV/EV, and powertrain.

Additionally, the TLV237x-Q1 family supports a high common-mode rail to the supply voltage. This feature sets no gain limitations and can support the input at any level without the concern for any phase reversal.
