| 99W088A 3 wire serial sound control IC BH3862FS Description BH3862FS is a sound control IC that includes a 4 input selector, volume and a 2 band tone. REC output terminals are located between the 4 input selector and the volume. Either 0dB or 18dB gain can be chosen. Functions such as stereo/monaural mode selection and mute are provided. Dimension (Units : mm) SSOP-A24 Features 1) Built-in 4-input selector, mute circuit, REC gain amplifier, volume, bass and treble. 2) 3-wire serial interface 3) Resistor ladder type volume control that uses a BiCMOS process for low noise and distortion. 4) SSOP-A24 package Applications Mini component stereo, Micro component stereo, Radio cassette recorder November, 1999 Absolute Maximum Ratings (Ta=25C) Parameter Supply voltage Power dissipation Operating temperature range Storage temperature range Symbol VCC Pd Topr Tstg Limits 6.0 650 * Unit V mW C C -40 ~ + 85 -55 ~ + 125 * Derating : 6.5mW/C for operation above Ta=25C.
