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

The value is 300mW when the IC is used alone. This value is the value measured when mounted on a glass epoxy board (50mm × 50mm × 1.6mm). This value is the value measured when mounted on a glass epoxy board (70mm × 70mm × 1.6mm).

notes •Operationcircuit connections (1) Unused 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 potential within the in-phase input voltage range (VICM). (2) If used with a voltage follower, be careful of oscillation 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 oscillation.
