FEATURES

200 Nanoseconds settling to 0.01%

100V/Microsecond slew rate

100 MHz Minimum gain-bandwidth

1 Microvolt/°C drift

±50 mA Output current

The AM-500 series amplifiers are ultra-fast

settling operational amplifiers for use in inverting

applications. A unique feedforward amplifier design

combines the characteristics of a low drift dc

amplifier with those of a very fast AC amplifier. For

optimum fast settling performance, this amplifier

has an open loop gain roll-off of 6 dB per octave

to beyond 100 MHz. Miniature thin-film hybrid

construction permits an optimum combination of

semiconductor devices and minimum lead lengths

to realize the amplifier circuitry. Applications

for the AM-500 Series include fast integrators,

sample-holds, fast waveform drivers, and fast D/A

converter output amplifiers.

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

ance, and 1 nanoampere bias current. Input offset

voltage is ±0.5 mV and input offset voltage drift

is 1 microvolt/°C. Although these amplifiers do

not operate differentially, a dc offset voltage in

the range of ±5V dc can be applied to the positive

input terminal.

Power supply requirement is ±15V dc at 22 mA

quiescent current. The amplifiers will operate over

a supply range of ±10V to ±18V dc. Output current

capability is ±50 mA with output short circuit

protection. Three basic versions are available:

AM-500GC and AM-500MC for 0°C to + 10°C, and

the AM-500MM for -55°C to +125°C. The device

package is a 14-pin ceramic DIP.
