High Slew Rate, Wide
Bandwidth, JFET Input
Operational Amplifiers
These devices are a new generation of high speed JFET input monolithic
operational amplifiers. Innovative design concepts along with JFET
technology provide wide gain bandwidth product and high slew rate.
Well–matched JFET input devices and advanced trim techniques ensure low
input offset errors and bias currents. The all NPN output stage features large
output voltage swing, no deadband crossover distortion, high capacitive
drive capability, excellent phase and gain margins, low open loop output
impedance, and symmetrical source/sink AC frequency response.
This series of devices is available in fully compensated or
decompensated (AVCL2) and is specified over a commercial temperature
range. They are pin compatible with existing Industry standard operational
amplifiers, and allow the designer to easily upgrade the performance of
existing designs.
Wide Gain Bandwidth: 8.0 MHz for Fully Compensated Devices
Wide Gain Bandwidth: 16 MHz for Decompensated Devices
High Slew Rate: 25 V/µs for Fully Compensated Devices
High Slew Rate: 50 V/µs for Decompensated Devices
High Input Impedance: 1012
Input Offset Voltage: 0.5 mV Maximum (Single Amplifier)
Large Output Voltage Swing: –14.7 V to +14 V for
Large Output Voltage Swing: VCC/VEE = ±15 V
Low Open Loop Output Impedance: 30 @ 1.0 MHz
Low THD Distortion: 0.01%
Excellent Phase/Gain Margins: 55°/7.6 dB for Fully Compensated
