BA10324A / BA10324AF / BA10324AFV
The BA10324A, BA10324AF, and BA10324AFV are monolithic ICs with four built-in operational amplifiers featuring
internal phase compensation.
Either a dual or single power supply can be driven, and these products can be driven by a digital system 5V single
power supply. These products can be used in a wide range of administrative and industrial applications, including
transducer amplifiers and DC amplifiers.

Applications
Ground sensing type pre-amplifiers
Active filters
DC amplifiers
Pulse generators.
•
Features
1) Wide range of operating power supply voltages and
single power supply drive enabled.
(single power supply: 3 to 32V, dual power supply: ±
1.5 to ± 16V)
2) Common-mode input voltage can be operated from
the ground level.
3) Differential input voltage can be operated up to the
power supply voltage level.
4) Low current dissipation. (IQ = 0.6mA)
5) Low offset voltage and offset current. (VIO = 2mV, IIO
= 5nA typ.)
6) Four operational amplifiers with phase compensa-
tion are built into the DIP / SOP Pin 14.
7) Compatible with model 324 operational amplifiers of
other manufacturers.
