The THS4513 is a wideband, fully differential op amp designed for 3.3 V to 5 V data-acquisition systems. It has very low noise at 2.2 nV/ load. Slew rate is very high at 5100 V/µs and with settling time of 5.5 ns to 1% (2 V step), it is ideal for pulsed applications. It is suitable for minimum gain of 6 dB.

To allow for dc coupling to ADCs, its unique output common-mode control circuit maintains the output common-mode voltage within 5 mV offset (typ) from the set voltage, when set within 0.5 V of mid-supply, with less than 4 mV differential offset voltage. The common-mode set point is set to mid-supply by internal circuitry, which may be over-driven from an external source.

The input and output are optimized for best performance with their common-mode voltages set to mid-supply. Along with high performance at low power supply voltage, this makes for extremely high performance single supply 5 V data acquisition systems.

The THS4513 is offered in a 16-pin ceramic flatpack package (W), and is characterized for operation over the full military temperature range from -55°C to 125°C.
