com Audio ICs LED level meter driver, 5-point, linear scale BA6104 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.
