The THS4509-Q1 is a wideband, fully differential operational amplifier designed for 5-V data-acquisition systems. It has very low noise at 1.9 nV/√Hz, and extremely low harmonic distortion of –75-dBc HD2 and –80-dBc HD3 at 100 MHz with 2 Vpp, G = 10 dB, and 1-kΩ load. Slew rate is very high at 6600 V/µs and with settling time of 2 ns to 1% (2-V step), it is ideal for pulsed applications. It is designed for minimum gain of 6 dB but is optimized for gain of 10 dB.

To allow for dc coupling to analog-to-digital converters (ADCs), its unique output common-mode control circuit maintains the output common-mode voltage within 3-mV offset (typical) 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 overdriven 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 THS4509-Q1 is offered in a quad 16-pin leadless QFN package (RGT) and is characterized for operation over the full automotive temperature range from –40°C to 125°C.
