AM-500 Series

Ultra-Fast Operational ꢀmpliﬁers

PRODUCT OVERVIEW

The ꢀM-±00 series ampliﬁers are ultra-fast

settling operational ampliﬁers for use in inverting

applications. ꢀ unique feedforward ampliﬁer design

combines the characteristics of a low drift dc

ampliﬁer with those of a very fast ꢀC 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. ꢀpplications

for the ꢀM-±00 Series include fast integrators,

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

converter output ampliﬁers.

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

input terminal.

Power supply requirement is ±1±V dc at 22 mꢀ

quiescent current. The ampliﬁers will operate over

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

capability is ±±0 mꢀ with output short circuit

protection. Three basic versions are available:

ꢀM-±00GC and ꢀM-±00MC for 0°C to + 10°C, and

the ꢀM-±00MM for -±±°C to +12±°C. The device

package is a 14-pin ceramic DIP.

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

PERFORMANCE

1. The circuit design shows the connection of the ꢀM-±00 series for fast

settling operation with a closed loop gain of -1. It can be used for fast

settling at closed loop gains up to -10. The equivalent resistance seen

by the summing junction should be ±00 ohms or less. For gains larger

than - 1 use an input resistor of ±00 ohms and pick a feedback resistor

for the required closed loop gain (1k for -2, 1.±k for -3, etc.).

3. Summing point leads must be kept as short as possible. Input and

feedback resistors should be soldered close to the body of the resistor

directly to the summing point (pin 4). Summing point capacitance to

ground must be kept very low.
