Address Recognition Output. AOUT drives low after successful chip address
recognition.
Address Programming Inputs. Connect to DGND or V
Individual Output Address Mode (Table 3).
Serial Data Output. In Complete Matrix Mode, data is clocked through the 112-bit
Matrix Control Shift register. In Individual Output Address Mode, data at DIN
passes directly to DOUT.
Serial Clock Input
Clock Enable Input. Drive low to enable the serial data interface.
Serial Interface Mode Select Input. Drive high for Complete Matrix Mode (Mode
1), or drive low for Individual Output Address Mode (Mode 0).
Asynchronous Reset Input/Output. Drive RESET low to initiate hardware reset. All
matrix settings are set to power-up defaults and all analog outputs are disabled.
Additional power-on reset delay may be set by connecting a small capacitor from
RESET to DGND.
Update Input. Drive UPDATE low to transfer data from mode registers to the
matrix switch.
Serial Data Input. Data is clocked in on the falling edge of SCLK.
No Connection. Not internally connected. Connect to AGND.
Digital Logic Supply. Bypass V
Buffered Analog Outputs. Gain is individually programmable for A V = +1V/V or
A V = +2V/V through the serial interface. Outputs may be individually disabled
(high impedance). On power-up, or assertion of RESET, all outputs are disabled.
