D/A Current to Voltage Conversion

The LT

operation on

±5V, and a single 5V supply. Unlike many

high speed amplifiers, this amplifier features high open-

loop gain, over 85dB, and the ability to drive heavy loads

to its very fast slew rate, the LT1190 features a unity-

gain-stable bandwidth of 50MHz and a 75

° phase margin,

making it extremely easy to use.

Because the LT1190 is a true operational amplifier, it is an

ideal choice for wideband signal conditioning, fast inte-

grators, active filters, and applications requiring speed,

accuracy and low cost.

The LT1190 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.
