DESCRIPTIO
The LT
high speed and precision performance.
A 26V/µs slew rate and 8.5MHz gain-bandwidth product
are simultaneously achieved with offset voltage of
typically 80µV, 1.5µV/°C drift, bias currents of 50pA at
70°C, 500pA at 125°C. The output delivers 20mA of load
current without gain degradation.
The 250µV maximum offset voltage specification
represents less than 1/2 least significant bit error in a
14-bit, 10V system.
The LT1022A meets or exceeds all OP-16A and OP-16E
specifications. It is faster and more accurate without
stability problems at cold temperatures.
The LT1022 can be used as the output amplifier for 12-bit
current output D/A converters, as shown below.
For a more accurate, lower power dissipation, but slower
JFET input op amp, please refer to the LT1055 data sheet.
