IC902 VHiADC08351-1: A/D Converter (ADC08351)
1 OE CMOS/TTL compatible digital input terminal.
When this terminal is set to Low, digital output of ADC08351 becomes enable.
When this terminal is set to High, digital output changes to the high-impedance condition.
2 DGND Ground return circuit terminal for digital power supply.
3-10 D0-D7 Conversion data output terminal. C0 shows LSB, and D7 shows MBS.
Effective data are output on data bus immediately after CLK input rising edge.
When OE terminal is set to Low, these terminals become enable.
11 VD Positive digital power voltage terminal. Connected to +3V power supply.
VA and VD are supplied from the common power supply.
12 CLK CMOS/TTL compatible clock input terminal. VIN is sampled at CLK input trailing edge.
13 VD Positive digital power voltage terminal. Connected to +3V voltage power.
14 VREF Positive reference voltage input terminal. Voltage of this terminal ranges from 0.75V to VA.
15 PD CMOS/TTL compatible digital input terminal.
When this terminal is set to High, ADC08351 enters the power down mode, minimizing power consumption.
When this is set to Low, the device enters the normal operation mode.
16 VA Positive analog power voltage terminal: To connect +3V voltage power.
17 VIN Analog signal input. Convertible input ranges from 0.5Vp-p to 0.68Va.
18, 19 AGND Ground return circuit terminal for analog power supply.
20 DGND Ground return circuit terminal for digital power supply.
