ADC0809 DIY Kits AD 8 Channel Analog to Digital Conversion Module

Parameter:

• PCB size:3.4*5.2cm

• Power apply:5V

• Interface instruction:

• VCC: power postive

• GND: power negative

• IN0-IN7: 8 channel analog data input port

• D0-D7:8bit data output port

• CLK:ADC0809 clock

• OE:output enable signal,high level is available.

• EOC:end of conversion signal,high level is available.

• STR:start conversion signal

Jumper:

• J7:potentiometer enable control.if short J7 by jumper cap,potentiometer connect to IN3.

• J8:control connection of VREF+ and VCC.if short J8 by jumper cap,VRET+ = VCC.if not,you can input reference voltage to VREF+.

• J9:control connection of VREF- and GND.if short J9 by jumper cap,VRET- = GND.if not,you can input reference voltage to VREF-.

• J3/J4/J4:control address of analoy input.also can control by MCU.
