The TLV246x is a family of low-power rail-to-rail input/output operational amplifiers specifically designed for portable 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 ideal for buffering analog-to-digital converters. The operational amplifier has 6.4 MHz of bandwidth and 1.6 V/μs of slew rate with only 500 μA of supply current， providing good ac performance with low power consumption. Three members of the family offer a shutdown terminal， which places the amplifier in an ultralow supply current mode （IDD = 0.3 μA/ch）。 While in shutdown， the operational-amplifier output is placed in a high-impedance state. DC applications are also well served with an input noise voltage of 11 nV/√Hz and input offset voltage of 100 μV. This family is available in the low-profile SOT23， MSOP， and TSSOP packages. The TLV2460 is the first rail-to-rail input/output operational amplifier with shutdown available in the 6-pin SOT23， making it perfect for high-density circuits. The family is specified over an expanded temperature range （TA = ?40°C to 125°C） for use in industrial control and automotive systems， and over the military temperature range （TA = ?55°C to 125°C） for use in military systems.
