ITEM NAME:ADC0809 Module AD Converter 8 Channel Parallel Digital Voltmeter Module Product Description Description: ADC0809 Module 8 Relay Parallel AD Conversion Module Digital Voltmeter Analog Digital Conversion Module ADC0809 Module AD Converter 8 Channel Parallel Digital Voltmeter Analog Digital Conversion Module Descriptions: 1. ADC0809 is a National Semiconductor 8-channel, 8-bit successive approximation A / D analog-to-digital converter manufactured by National Semiconductor. 2. Its internal has an 8-channel multi-channel switch, which can be encoded according to the address code after the signal, only through the 8 analog input signal for a A / D conversion. Features: 1. 8 input channels, 8-bit A / D converter, the resolution is 8 bits. 2. Has a conversion start and stop control terminal. 3. Conversion time is 100s (when clock is 640kHz), 130s (when clock is 500kHz). 4. Single + 5V power supply. 5. Analog input voltage range 0 ~ + 5V, no zero and full scale calibration. 6. Operating temperature range of -40 ~ +85 degrees Celsius. 7. Low power consumption, about 15mW. 8. The module size is: 5.5 * 4.2cm/2.16*1.65'' 9. Module built a precision potentiometer, can be used for voltmeter experiment. 10. Address for single-chip selection, but also jumper cap selection. 11. Need to use the input and output are drawn with a needle is very convenient. Note: Please allow 1-3cm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
