Standard ICs
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.
Features
•
1) Low-voltage operation.
2) High slew rate.
3) Wide dynamic output range.
4) Compact 8-pin SSOP-B package. (BA4510FV)

1 If used at temperatures higher than 25°C, reduce power by 5.5mW for each 1°C above Ta = 25°C.
This value is the value measured when mounted on a glass epoxy board (50mm × 50mm × 1.6mm).
2 If used at temperatures higher than 25°C, reduce power by 3.5mW for each 1°C above Ta = 25°C.
This value is the value measured when mounted on a glass epoxy board (70mm × 70mm × 1.6mm).
The value is 300mW when the IC is used alone.

Operation notes

VCC
(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 (VICM).
(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.
