XR-146/246/346
Programmable Quad Operational Amplifiers
GENERAL DESCRIPTION
The XR-146 family of quad operational amplifiers con-
tain four independent high-gain, low-power, program-
mable op-amps on a monolithic chip. The use of exter-
nal bias setting resistors permit the user to program
gain-bandwidth product, supply current, input bias cur-
rent, input offset current, input noise and the slew rate.
The basic XR-146 family of circuits offer partitioned
programming of the internal op-amps where one set-
ting resistor is used to set the bias levels in the three
op-amps, and a second bias setting is used for the re-
maining op-amp. Its modified version, the XR-346-2 pro-
vides a separate bias setting resistor for each of the
two op-amp pairs.
FEATURES
Programmable
Micropower operation
Low noise
Wide power supply range
Class AB output
Ideal pin out for biquad active filters
Overload protection for input and output
Internal frequency compensation
APPLICATIONS
Total Supply Current = 1.4 mA (lSET/1 0 pA)
Gain Bandwidth Product = 1 MHz (lSET/10pA)
Slew Rate = O.4V/ps (ISET/10 pA)
Input Bias Current == 50 nA (lSET/10 pA)
ISET = Current into pin 8, pin 9 (see schematic)
