Industry standard
DATEL’s AM-1435 is an ultrafast settling,
wideband operational amplifier. Utilizing preci-
sion 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, 1MΩ 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 appli-
cations requiring high accuracy in the amplification
of complex wideband waveforms. Such applica-
tions 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.
