Quad ground sense operational
amplifier
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.

Features of operating power supply voltages and
1) Wide range
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. (I
Q
= 0.6mA)
5) Low offset voltage and offset current. (V
IO
= 2mV, I
IO
= 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.
