BA3118L General Description


The BA3118L is a dual-channel line amplifier with a flat frequency characteristic. It has been designed for use in radio cassette players and car stereos.

The feedback resistors are all on the chip, which reduces the number of external components required and simplifies PCB design. The gain can be set to one of 10 gain settings from 6dB to 20dB (6dB, 8dB, 10dB, 10.9dB, 12.4dB, 13.4dB, 15.1dB, 16dB, 17.9dB and 20dB), and external fine trimming is possible.

BA3118L Features

1) 10 gain settings over the range 6dB to 20dB (max.
step 2dB) without external resistors.
2) Low distortion.
3) Good crosstalk characteristics.
4) Low noise.
5) Flat frequency characteristic.
6) Two channels on one chip allows compact set design.
7) Pin 9 is not connected which simplifies the PBC GND design.
8) Built-in feedback resistors reduces the number of external
components required.
9) Low gain variance between the two channels.
