BH3854AS Product details

Description

634 Audio ICs BH3854AS / BH3854AFS FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 8V, f = 1kHz, BW = 20 X 20kHz, VOL = Max., TONE = ALL FLAT, Rg = 600Ω, RL = 10kΩ, INPUT AMP GAIN = 0dB) FTiming chart constants Note: About the output pins SPins 1 through 4 (pins 12 through 15) are reset when the power is turned ON.SAfter the pins are reset, until the Vcc voltage setting for this IC (BH3854) is reached and the next data Sis input, the pins only operate while the CK,

Features

1) They facilitate direct serial control from a microcomputer of volume (main volume) and tone (bass, treble). DC control is also possible. 2) Volume is produced by a low-distortion, low-noise VCA. Designed to minimize step noise. 3) Input amp can be used for gain adjustment, and matrix surround yields powerful sound. 4) Stable standard voltage supply and built-in I / O buffer mean that few attachments are needed. SSOP32 package designed to save space. FAbsolute maximum ratings (Ta = 25_C) 5) Op.
