FEATURES
200 Nanoseconds settling to 0.01% 100V/Microsecond slew rate 100 MHz Minimum gain-bandwidth 106 Open loop gain 1 Microvolt/°C drift ±50 mA Output current FUNCTIONAL BLOCK DIAGRAM PRODUCT OVERVIEW A unique feedforward amplifier design combines the characteristics of a low drift dc amplifier with those of a very fast AC amplifier. Miniature thin-film hybrid construction permits an optimum combination of semiconductor devices and minimum lead lengths to realize the amplifier circuitry. Output settling time is 200 nanoseconds maximum to 0.01% for a 10 dc volt step change. Slew rate is 1000V/microsecond for positive output transitions and 1800V/microsecond for negative transitions. This high slew rate permits undistorted reproduction of a full load, 20V peak-to-peak sinewave out to 16 MHz. Gain bandwidth product is 100 MHz minimum. AM-500 series dc characteristics include a dc open loop gain of 106, 30 megohm input impedance, and 1 nanoampere bias current. Input offset voltage is ±0.5 mV and input offset voltage drift is 1 microvolt/°C.
