ELECTRONIC VOLUME CONTROL IC
TC9210P and TC9211P are electronic volume control ICs
developed for use in audio equipment such as home
stereo sets.
The volume, balance and loudness circuits can be
controlled by serial data which are input externally.
FEATURES
0 Forty-level volume control in 2dB steps from OdB to
78dB, ccrdB.
0 The volume circuit features 2 built-in channels which can
be controlled independently, thus controlling balance.
0 TC9211P features a built-in loudness circuit (20dB tap).
lt Single and dual power supply operation.
0 Chip select input allows control of up to four of these
chips on the same bus.
0 Polysilicon resistors enables low-distortion, high-
performance volume systems.

OPERATIONAL DESCRIPTION
1. Setting volume values (attenuation)
The volume values are set using 13bit serial data.
0 Data format
(LSB) (MSB)
DATA lLlRlo1lD2lD3lsrlDsloslLDlc1lc2lc3lcol
1) L is left-channel select data ; R is right-channel select data.
When L=1, left-channel volume is set ; when R=1, right-channel volume is set. (When R=L=1,
both channel volumes are set simultaneously).
2) LD is loudness setting data. When LD-- l, loudness is on. (Only for TC9211P. Set to 0 for
TC9210P.)
3) D1-D6 are volume value setting data.
