BH3864F

Audio ICs Audio sound controller BH3864F The BH3864F has been developed for use in mini-component stereo systems. Switching is done using a resistor ladder to suppress DC offset at switching. Two-line serial control is available, and external three-line serial control is also possible. The package is a compact 24-pin SOP. FApplications Mini-and micro-component stereo systems, CD radio cassette players and TVs. FFeatures 1) Volume, tone, and dynamic bass boost control possible by a serial link to a microprocessor. 2) Left and right channel volume can be controlled independently. FAbsolute maximum ratings (Ta = 25_C) 3) Resistor-ladder type volume control uses BiCMOS process for low distortion and noise. 4) Dynamic bass and linked ALC are provided on chip. FRecommended operating conditions (Ta = 25_C) 534 Audio ICs FBlock diagram BH3864F 535 Audio ICs FPin descriptions BH3864F FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 9V, f = 1kHz, Rg = 600Ω, RL = 10kΩ, FBW = 20Hz to 20kHz, VIN = 200mVrms, volume = 0dB, tone = 0dB, dynamic bass = 0dB, and gain select = 14dB) 536 Appendix Notes No technical content pages of this document may be reproduced in any form or transmitted by any means without prior permission of ROHM CO.,LTD.
