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 |
