Product Details
The LT1022 JFET input operational amplifier combines 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.
Applications
- Fast D/A Output Amplifiers (12, 14, 16 Bits)
- High Speed Instrumentation
- Fast, Precision Sample and Hold
- Voltage-to-Frequency Converters
- Logarithmic Amplifiers
