DESCRIPTION The THS4511 is a wideband, fully-differential operational amplifier designed for single-supply 5-V data-acquisition systems. It has very low noise at 2 nV/√Hz, and extremely low harmonic distortion of –72 dBc HD2 and –87 dBc HD3 at 70 MHz with 2 VPP, G = 0 dB, and 200-Ω load. Slew rate is very high at 4900 Vµs and with settling time of 3.3 ns to 1% (2 V step) it is ideal for pulsed applications. It is designed for minimum gain of 0 dB. To allow for d...
