Dual high slew rate operational
amplifier
BA4510F / BA4510FV
The BA4510F and BA4510FV are monolithic ICs that contain two operational amplifiers with high slew rate, featuring
phase compensation. These ICs can be driven with a low-voltage power supply, requiring a power supply range of
1 to 3.5V for a dual power supply and 2 to 7V for a single power supply. In addition, an unbuffered type is used
which enables ample output even in low voltage ranges, enabling swing at up to nearly the power supply voltage.

1 If used at temperatures higher than 25
C, reduce power by 5.5mW for each 1

Operation notes
(1) Unused circuit connections
If there are any circuits which are not being used, we
recommend making connections as shown in Figure 2,
with the non-inverted input pin connected to the poten-
tial within the in-phase input voltage range (V
ICM
).
(2) If used with a voltage follower, be careful of oscilla-
tion which may cause problems with the in-line input
voltage range or the capacitance load.
(3) If using at power supply voltage + 5.0 or higher, be
sure the gain is reduced sufficiently to prevent oscilla-
tion.
