FEATURES
GENERAL DESCRIPTION
DATEL’s AM-1435 is an ultrafast settling, wideband
operational amplifier. Utilizing precision thin-film hybrid
construction and differential input operational amplifier design
techniques, the AM-1435 achieves a settling time of only 70
nanoseconds for a 10V step to ±0.01% accuracy. High-speed
performance is optimized with high open-loop gain, flat
frequency response beyond 10kHz, and a roll-off of 6dB/
octave to beyond 100MHz. Typically, gain bandwidth product
is 1GHz, and slew rate is ±300V/microsecond.
AM-1435’s dc characteristics include a dc open loop gain of
100dB, 1M input impedance, and an initial input offset
voltage of only ±2mV. Input offset voltage drift is typically
±5µV/°C. Also featured is a minimum common mode rejection
ratio of 80dB and full power frequency of 8MHz.
The AM-1435 is designed specifically for applications requiring
high accuracy in the amplification of complex wideband
waveforms. Such applications include radar and sonar signal
processing, video instrumentation, ultrafast A/D and D/A
converters and sample-hold amplifiers.
Power supply requirements are ±15V at 30mA maximum
quiescent current. Models are specified for operation over the
commercial (0 to +70°C) and military (–55 to +125°C)
temperature ranges. A high-reliability version manufactured
and screened to DATEL’s QL screening program is also
available. The package is a 14-pin ceramic DIP.

... R1 INPUT 1k TYPICAL CONNECTION AND COMPENSATION The typical connection diagram (above) shows the AM-1435 in a unity-gain inverting configuration. When used in any conventional operational-amplifier configuration, the AM-1435 (as a non-inverting amplifier) requires a noise gain of at least two (noise gain = 1 + R4/R1). The 2pF compensation capacitor, C1, at pin 3 is required for stable operation when the noise gain is less than 10 ...
