Features
1) Volume residual noise : 1.2碌 Vrms {Dynamic range : 131dB (IHF-A)}
2) Volume is 2ch-independence. (0 to -103dB, MUTE 1dB / step)
3) BUS is common and be possible to maximum 8channnel-ization of
6ch-Volume IC.
4) It can be controlled until 4 chips with common bus line at the same time.
5) Maximum output voltage : 4.2Vrms (Vcc=7V, V
EE
=鈭?V, RL=10k鈩?
6) The serial data control of 2-wire type. (correspond to 3.3V and 5V)
7) Built-in the convenient output gain amp.(0, 6 to 18dB, 2dB / step) for the
adjustment of the output signal.
8) Output mute be able to serial data and external mute terminal both.
