Exar XR-1458
XR-1458/4558
Dual Operational Amplifier
GENERAL DESCRIPTION
The XR-1458/4558 is a pair of independent internally
compensated operational amplifiers on a single silicon
chip, each similar to the popular 741, but with a power
consumption less than one 741. Good thermal tracking
and matched gain-bandwidth products make these Du-
al Op-amps useful for active filter applications.

Note 1: For supply voltages less than ± 15V, the absolute max-
imum input voltage is equal to the supply voltage.
Note 2: Short circuit may be to ground or either supply. Rating
applies to + 125°C case temperature of + 75°C ambi-
ent temperature for XR1458/4558.
Note 3: Rating applies for case temperatures to 125°C; derate
linearly at 6.5mW/oC for ambient temperatures above
+ 75°C for XR1458/4558.

SYSTEM DESCRIPTION
The XR-1458 and XR-4558 are dual general purpose op
amps featuring better performance than industry stan-
dard devices such as the 741; bandwidth, slew rate,
and input resistance are greatly improved. Internal pro-
tection circuitry includes latch-up elimination, short cir-
cuit current limiting, and internal compensation.
The two amplifiers are completely independent, shar-
ing bias circuitry only.
