The THS4520 is a wideband, fully differential operational amplifier designed for 5-V data acquisition systems. It has very low noise at 2 nV/Hz, and low harmonic distortion of 115 dBc HD2 and 123 dBc HD3 at 100 kHz with 8 VPP, and 1-k load. The slew rate is 570 V/s, 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.
