C-Load Op Amp Drives All Capacitive Loads DC gain than devices with comparable bandwidth. The
n
10nV/Hz Input Noise Voltage circuit topology is a voltage feedback amplifier with the
n
800V Maximum Input Offset Voltage slewing characteristics of a current feedback amplifier.
n
300nA Maximum Input Bias Current The amplifier is a single gain stage with outstanding
n
70nA Maximum Input Offset Current settling characteristics which makes the circuit an ideal
