• 10-dB volume control inputs

• These inputs must be driven from low-impedance circuits.

Outputs from the input selector

Signal inputs

Power supply connection

Ground

Chip enable. Data is latched internally at the point this pin goes from high to

low. The analog switches operate at that point. Data transfer is enabled when

this pin is high.

Inputs for the serial data and clock used for LSI control.

Test input (Must be left open during normal operation.)

10-dB block outputs

• 1-dB block inputs

• These inputs must be driven by low-impedance circuits.

No-connection pins.
