说明

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 V_PP, G = 0 dB, and 200- 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 dc coupling to analog-to-digital converters (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 midsupply.
