neoPLC ADC – High-speed 12-bit, 8-channel Voltage Input

Measure up to eight voltage sources with this high speed Analog-to-Digital Converter (ADC). Great for expanding the available input channels on a neoPLC uC or any other micro-controller with i2c. Perfect for knobs and sliders (rotary and linear potentiometers), thousands of analog sensor ICs, as well as thermistors and photo-resistors with bias resistors.

SPECS:

• 8-channel
• 12-bit ADC
• 50 kHz sample rate
• 0-3.3V range
• Address pads allow up to 4 ADC boards at once

DATASHEET: ADS7828

// include the neoPLC-ADC library
#include <neoADC.h>
// create an instance of the ADC board
neoADC adc = neoADC();

// --- SETUP ---
// initialize the ADC board
void adc.begin();

// --- METHODS ---
// read the voltage at channel 'x', store in 'val' 
float val = adc.read(int x);
