Description

Serial input pin for command data.

Serial output pin for status data.

Shift clock input pin for the Dl and the DO pins.

Chip select pin. “L” level input enables data input/output through the serial

interface.

RESET input pin, resetting the serial interface circuit only. “L” level input to

this pin initializes the serial interface. Must input “L” pulse after each

power-on.

Insert a 30 kΩ resistor (Precision within ±1%) between this pin and the

DGND pin. The same resistor should also be inserted if an external clock

is used. The resistor value determines the frequency of the clock for

control in this device.

External clock input pin. Allowable clock frequency range is 4.0 to 8.192

MHz. When external clock is unused and internal oscillation clock is used,

connect this pin to the DGND.

Output “H” level during recording/playback operation.

Analog reference voltage (Signal Ground Voltage) output pin. It is

recommendable to insert a capacitor of 3300 pF or less between this pin

and the AGND pin. Loads except for capacitors should not be connected

to this pin.

Inverting input pin for the internal OP amplifier. Non-inverting input pin is

internally connected to SG voltage.

Output pin from the internal OP amplifier.

Analog waveform output. Connect to an amplifier to drive a SP.

TEST2

O Pins for testing the LSl. Must be held “OPEN”.
