Description

BH3857AFV 666 Audio ICs BH3857AFV FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 8V, f = 1kHz, BW = 20Hz to 20kHz, VOL = MAX, Tone = ALL FLAT, Rg = 600Ω, RL = 10kΩ, INPUT_AMP_GAIN = 0dB) 667 Audio ICs FMeasurement circuit BH3857AFV 668 Audio ICs FCircuit operation (1) About the data format As shown in Fig.2, there are 32 bits of data.When the power is applied, a reset is applied to switch ports 1 to 4 off, but the reset is not applied to the other ports, so th

Features

1) Volume (main volume) and tone (bass and treble) control possible by direct serial link to a microprocessor. DC control is also possible. 2) Volume control is done with a low-distortion, lownoise VCA, and step noise is suppressed. 3) The gain of the input amplifier can be adjusted, and two surround matrixes are available to expand the sound. 4) The IC includes a stable reference voltage source and input buffer to reduce external component requirements, and comes in a compact 40-pin SSOP packa.
