Description

The THS4509 is a wideband, fully differential op amp designed for 5-V data acquisition systems. It has a low noise at 1.9 nV/√Hz, and 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 high at 6600 Vµs, 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 ADCs, its unique output common-mode control circuit maintains the output common-mode voltage within 3 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 high performance single supply 5-V data acquisition systems. The combined performance of the THS4509 in a gain of 10 dB driving the ADS5500 ADC, sampling at 125 MSPS, is 81 dBc SFDR and 69.1 dBc SNR with a -1 dBFS signal at 70 MHz.

The THS4509 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.
