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.
Typical Application |
Features |
| ·Signal meters, tuning meters and voltage checkers. | · 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. |
