The THS4520 is a wideband, fully differential operational amplifier designed for 5-V data acquisition systems. It has very low noise at 2 nV/ load. The slew rate is 570 V/µs, and with a settling time of 7 ns to 0.1% (2-V step), it is ideal for data acquisition applications. It is designed for unity gain stability.

To allow for dc coupling to ADCs, its unique output common-mode control circuit maintains the output common-mode voltage within 0.25 mV offset (typical) from the set voltage. The common-mode set point defaults 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 and 3.3-V data acquisition systems.

The THS4520 is offered in a Quad 16-pin leadless QFN package (RGT), and is characterized for operation over the full industrial temperature range from –40°C to 85°C.
