JFET Input Operational Amplifiers
General Description

These arethe first monolithic JFET input operational ampli-
fiersto incorporate well matched, high voltage JFETsonthe
same chip with standard bipolar transistors (BI-FET™ Tech-
nology). These amplifiers feature low input bias and offset
currents/low offset voltage and offset voltage drift, coupled
with offset adjust which does not degrade drift or
common-mode rejection. The devicesare also designedfor
high slew rate, wide bandwidth, extremely fast settling time,
low voltage and current noise anda low1/f noise corner.
Features
Advantages
Replace expensive hybrid and module FETop amps Rugged JFETs allow blow-out free handling compared
with MOSFET input devices Excellentfor low noise applications using either highor
low source impedance —very low1/f corner Offset adjust does not degrade driftor common-mode
rejectionasin most monolithic amplifiers New output stage allows useof large capacitive loads
(5,000 pF) without stability problems Internal compensation and large differential input voltage
capability
Applications
Precision high speed integrators Fast D/A and A/D converters High impedance buffers Wideband, low noise, low drift amplifiers Logarithmic amplifiers Photocell amplifiers Sample and Hold circuits
Common Features
Low input bias current: 30pA Low Input Offset Current: 3pA High input impedance: 1012Ω Low input noise current: High common-mode rejection ratio: 100dB Largedc voltage gain: 106dB
