Description

The BA6104 is a monolithic driver IC for LED level meters applications.

The IC has five comparators that operate in equally-spaced steps in response to the input voltage, and drive bar-display output LEDs.

When the reference voltage generator is not set (pin 7 open), the comparators operate in 200mV (approx.) steps, so an input level of about 1V lights all of the LEDs. By connecting external resistors between pin 7 and GND. and pin 7 and VCC, this level can be adjusted over the range 0.5V to 3.0V.
