DUAL LOW-POWER OPERATIONAL AMPLIFIERS

SLOS086 – D2567, OCTOBER 1979 – REVISED OCTOBER 1990

• Wide Range of Supply Voltages

Single Supply . . . 5 V to 30 V
Dual Supplies...± 2.5 V to ± 15 V

• Class AB Output Stage

• True Differential Input Stage

• Low Input Bias Current

• Internal Frequency Compensation

• Short-Circuit Protection

description

The TL322C and the TL322I are dual operational
amplifiers similar in performance to the uA741 but
with several distinct advantages. They are
designed to operate from a single supply over a
range of voltages from 5 V to 30 V . Operation from
split supplies is also possible provided the
difference between the two supplies is 5 V to 30 V .
The common-mode input range includes the
negative supply . Output range is from the negative
supply to V
per amplifier are typically less than one-half those
of the uA741.

The TL322C is characterized for operation from
0°C to 70°C. The TL322I is characterized for
operation from –40°C to 85°C.
