D/A Current to Voltage Conversion
The LT1192 is a video operational amplifier optimized for
operation on ±5V and a single 5V supply. Unlike many
high speed amplifiers, this amplifier features high open-
loop gain, over 100dB, and the ability to drive heavy loads
to a full-power bandwidth of 20MHz at 7V
P-P
. In addition
to its very fast slew rate, the LT1192 has a high gain
bandwidth of 350MHz and is compensated for a closed-
loop gain of 5 or greater.
Because the LT1192 is a true operational amplifier, it is an
ideal choice for wideband signal conditioning, active fil-
ters, and applications requiring speed, accuracy and low
cost.
The LT1192 is available in 8-pin PDIP and SO packages
with standard pinouts. The normally unused Pin 5 is used
for a shutdown feature that shuts off the output and
reduces power dissipation to a mere 15mW.
