JFET Input Operational Amplifiers  
n Logarithmic amplifiers  
n Photocell amplifiers  
These are the first monolithic JFET input operational ampli-  
n Sample and Hold circuits  
General Description  
fiers to incorporate well matched, high voltage JFETs on the  
Common Features  
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 devices are also designed for  
high slew rate, wide bandwidth, extremely fast settling time,  
low voltage and current noise and a low 1/f noise corner.  
n Low input bias current: 30pA  
n Low Input Offset Current: 3pA  
n High input impedance: 1012Ω  
n Low input noise current:  
n High common-mode rejection ratio: 100 dB  
n Large dc voltage gain: 106 dB  
Features  
Advantages  
Uncommon Features  
n Replace expensive hybrid and module FET op amps  
n Rugged JFETs allow blow-out free handling compared  
with MOSFET input devices  
n Excellent for low noise applications using either high or  
low source impedancevery low 1/f corner  
n Offset adjust does not degrade drift or common-mode  
rejection as in most monolithic amplifiers  
n New output stage allows use of large capacitive loads  
(5,000 pF) without stability problems
