The devices in the TLV246x-Q1 family of low-power rail-to-rail input/output operational
amplifiers are designed for battery management systems in HEV/EV and Powertrain, and lighting and
roof module systems in body and lighting applications. The input common-mode voltage range extends
beyond the supply rails for maximum dynamic range in low-voltage systems. The amplifier output has
rail-to-rail performance with high-output-drive capability, solving one of the limitations of older
rail-to-rail input/output operational amplifiers. This rail-to-rail dynamic range and high output
drive 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-µA
supply current, which provides good ac performance with low-power consumption. Devices are
available with an optional shutdown terminal, which places the amplifier in an ultra-low
supply-current mode (IDD = 0.3 µA per channel). While in shutdown, the
operational amplifier output is placed in a high-impedance state. DC applications are designed with
an input noise voltage of 11 nV/√Hz and input offset voltage of 100 µV.
