General-purpose dual line amplifier

BA3118L

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.

FApplications

Car stereos and radio cassette players

FFeatures

1) 10 gain settings over the range 6dB to 20dB (max.

step 2dB) without external resistors.

2) Low distortion.

6) Two channels on one chip allows compact set de-

sign.

7) Pin 9 is not connected which simplifies the PBC GND

design.

3) Good crosstalk characteristics.

4) Low noise.

8) Built-in feedback resistors reduces the number of ex-

ternal components required.

5) Flat frequency characteristic.

9) Low gain variance between the two channels.

FAbsolute maximum ratings (Ta = 25_C)

FRecommended operating conditions (Ta = 25_C)
