Описание

The THS4511 is a fully differential operational amplifier designed for single-supply 5 V data-acquisition systems. It has very low noise at 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 designed 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 (typical) from the set voltage, when set within ±0.5 V of mid-supply. The common-mode set point is set to mid-supply by internal circuitry, which may be over-driven from an external source. The THS4511 is a high-performance amplifier that has been optimized for use in 5 V single-supply data acquisition systems. The output has been optimized for best performance with its common-mode voltages set to mid-supply, and the input has been optimized for performance over a wide range of common-mode input voltages. High performance at a low power-supply voltage enables single-supply 5 V data-acquisition systems while minimizing component count. The THS4511 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.
