TLV2464A-Q1 - Automotive Low-Power Rail-to-Rail Input/Output Operational Amplifier with Shutdown

Updated : 2020-01-09 14:21:20
Description

The devices in the TLV246x-Q1 family of low-power rail-to-rail input/output operationalamplifiers are designed for battery management systems in HEV/EV and Powertrain, and lighting androof module systems in body and lighting applications. The input common-mode voltage range extendsbeyond the supply rails for maximum dynamic range in low-voltage systems. The amplifier output hasrail-to-rail performance with high-output-drive capability, solving one of the limitations of olderrail-to-rail input/output operational amplifiers. This rail-to-rail dynamic range and high outputdrive make the TLV246x-Q1 designed for buffering analog-to-digital converters.

The operational amplifier has 6.4-MHz bandwidth and a 1.6-V/µs slew rate with only 500-µAsupply current, which provides good ac performance with low-power consumption. Devices areavailable with an optional shutdown terminal, which places the amplifier in an ultra-lowsupply-current mode (IDD = 0.3 µA per channel). While in shutdown, theoperational amplifier output is placed in a high-impedance state. DC applications are designed withan input noise voltage of 11 nV/√Hz and input offset voltage of 100 µV.
