BA2901F Information

Description

The ROHM Semiconductor BA2901F is a Quad Comparator IC with an open collector output, packaged in a SOP-14 format. It features high performance, low noise, and wide bandwidth, making it suitable for various applications. The IC operates on dual power supplies with a wide input voltage range of 3 to 28V. The BA2901F is commonly used as a voltage stabilizer in automotive electronics, such as audio systems, dashboard displays, and engine control units. It also finds application in industrial automation, medical devices, and consumer electronics to ensure stable power supply and protect sensitive components from voltage fluctuations.

Features

The ROHM Semiconductor BA2901F is a Quad Comparator, Open Collector O/P, with the following features:

  • High-performance operational amplifier IC
  • Operates on dual power supplies with a wide input voltage range (3V to 28V)
  • Open collector output stage for easy interfacing with other devices
  • Fast response time of 1.3μs

It is commonly used as a voltage stabilizer in automotive electronics, industrial automation, medical devices, and consumer electronics to ensure stable power supply and protect sensitive components from voltage fluctuations.

Package

The package type of BA2901F is SOP-14 (Shrink Small Outline Package, 14 pins).

Pinout

The BA2901F is a Quad Comparator IC with an open collector output, packaged in a SOP-14 package.

Pin Count: 14 pins

Functions:

  • Pins 1-4: Input (IN) for each comparator
  • Pin 5: Non-Inverting Input (VIN) for each comparator
  • Pin 6: Inverting Input (VIN-) for each comparator
  • Pin 7: Output (OUT) for each comparator
  • Pin 8: VCC (Positive Supply Voltage)
  • Pin 9: GND (Ground)
  • Pins 10-13: Unused
  • Pin 14: NC (No Connection)

Note that the BA2901F is a quad comparator IC, meaning it has four independent comparators on a single chip.
