Zero-cross control input 1. Select one from four types of zero-cross modes including nonzero cross mode. When
changing zero-cross modes during operation, set the system so that it changes at 1 second or more after the rise
of CSN signal.
Zero-cross control input 2. Select one from four types of zero-cross modes including nonzero cross mode. When
changing zero-cross modes during operation, set the system so that it changes at 1 second or more after the rise
of CSN signal.
Chip select input.
Serial data input.
Digital ground.
Reference voltage output for digital for attaining stabilization, connect this terminal to DVSS terminal through a
capacitance of 10 µF or higher (CREF).
And please do not use this terminal output for the drive purpose of an external circuit.
Minus power supply for digital (-6.0 V Typ.).
Serial clock input.
Serial data output.
Serial data are outputted from this terminal when CSN pin is “L” level.
This terminal becomes high-impedance state when CSN pin is “H”. Since it is an open drain output pin, pull it up
through a resistor to the power supply voltage (to be AVDD or less) of a device to be connected. Do not allow
output current of 1.5 mA or over.
Test terminal (Pull-down) non connection or connect to DGND terminal.
Test terminal (Pull-down) non connection or connect to DGND terminal.
Test terminal (Pull-down) non connection or connect to DGND terminal.
CH2 analog input. The output impedance of input signal source is used less than 10 kΩ.
When avoid the use of this terminal, connect to ground.
CH2 analog reference voltage input A connect to ground directly.
CH2 analog reference voltage input B connect to ground directly.
CH2 analog output.
Plus power supply for analog (+6.0 V Typ.).
Minus power supply for analog (-6.0 V Typ.).
Minus power supply for analog (-6.0 V Typ.).
Plus power supply for analog (+6.0 V Typ.).
CH1 analog output.
CH1 analog reference voltage input B connect to ground directly.
CH1 analog reference voltage input A connect to ground directly.
CH1 analog input. The output impedance of input signal source is used less than 10 kΩ.
When avoid the use of this terminal, connect to ground.
