Audio ICs 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. 3) Good crosstalk characteristics. 4) Low noise. 5) Flat frequency characteristic.
