LF13741 JFET Input operational amplifier DIP8
The LF13741 is a 741 with BI-FET
TLH9296
General Description
The LF13741 is a 741 with BI-FET
input followers on the
same die Familiar operating characteristicsthose of a
741with the added advantage of low input bias current
make the LF13741 easy to use Monolithic fabrication
makes this ??drop-in-replacement?? operational amplifier very
economical
Applications in which the LF13741 excels are those which
require low bias current moderate speed and low cost A
few examples include high impedance transducer amplifi-
ers photocell amplifiers buffers for high impedance slow to
moderate speed sources and buffers in sample-and-hold
type systems where leakage from the hold capacitor node
must be kept to a minimum
Systems designers can take full advantage of their knowl-
edge of the 741 when designing with the LF13741 to
achieve extremely rapid ??design times?? The LF13741 can
also be used in existing sockets to make the ??error budget??
for input bias andor offset currents negligible and in many
cases eliminate trimming For higher speed and lower noise
use the LF155 LF156 LF157 series of BI-FET operational
amplifiers
