BA6104 General 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.

BA6104 Features
· Drives an LED bar display in proportion to the input level.
· The output current can be set to a maximum of 15mA using external resistors, allowing free selection of the
type and color of the LEDs.
· The input level at which all LEDs light can be set in the range 0.5V to 3.0V using external resistors.
· High input impedance.
· Easy-to-handle 9-pin SIP package.
· The output current can be set to a maximum of 15mA using external resistors, allowing free selection of the
type and color of the LEDs.
· The input level at which all LEDs light can be set in the range 0.5V to 3.0V using external resistors.
· High input impedance.
