Description
I Input pins for data signals (D1: MSB, D8: LSB)
I Input pin for clock signal
— Digital power supply pin (+5 V)
— Analog power supply pin (+5 V)
— Digital ground pin (0 V)
— Analog ground pin (0 V)
Reference voltage input pin.
Used for setting dynamic range for analog output.
I
Connect this pin with either VROUT1 or VROUT2 pin when using the
internal reference voltage.
When using the external reference voltage, use it within the
range of 2.65 to 4.3 V or for the VCCA – VRIN range of 0.7 to 2.2 V.
Reference voltage output pin 1.
Resistance division reference voltage, with its output voltage set
O to 0.6 × VCCA.
This pin, if connected with the VRIN pin, provides VCCA analog
output voltage at 0.6 × VCCA.
Reference voltage output pin 2.
O
Band-gap reference voltage, with its output voltage set to VCCA
– 2 [V]. This pin, if connected with the VRIN pin, provides the VCCA
analog output voltage at VCCA 1 – 2 [V].
Phase compensated capacitance pin.
— Insert the capacitance of 0.1 µF or more between this pin and the
A.GND for the phase compensated capacitance.
O Analog signal output pin
— No connection pins
