Exar XR-4741
XR-4741
Quad Operational Amplifier
GENERAL DESCRIPTION
The XR-4741 is an array of four independent internally-
compensated operational amplifiers on a single silicon
chip, each similar to the popular 741. Each amplifier of-
fers performance equal to or better than the 741 type in
all respects. It has high slew rate, superior bandwidth,
and low noise, which makes it excellent for audio ampli-
fiers or active filter applications.

SYSTEM DESCRIPTION
The XR-4741 is a quad independently programmable
operational amplifier featuring improved performance
over industry standard devices such as the 741. Ampli-
fier bias currents can be "programmed" by a single re-
sistor to Pin 8. Bias currents can range from less than 1
p,A to over 75 p,A, thus affording the deSigner flexibility
along the device speed/power consumption trade off
curve.
