4PCS ADS1115 I2C IIC Analog-to-Digital Converter 4 Channel 16 Bit ADC Module Converter with Programmable Gain Amplifier Development Board

Product Description： It is a high precision ADS1115 16 Bit 4 Channel Analog-to-Digital ADC Converter. ADS1115 4-channel breakout boards are perfect for adding high-resolution analog to digital conversion to any microprocessor-based project. These boards can run with power and logic signals between 2v to 5.5v, so they are compatible with all common 3.3v and 5v processors. As many of 4 of these boards can be controlled from the same 2-wire l2C bus, giving you up to 16 single-ended or 8 differential channels. A programmable gain amplifier provides up to xl6 gain for small signals. The ADS1115 hashigher resolution. Features: Resolution: 16 Bits Programmable Sample Rate: 8 to 860 Samples/Second PowerSupply/Logic Levels: 2.0V to 5.5V Low Current Consumption: Continuous Mode: Only 150uA Single-Shot Mode: Auto Shut-Down Internal Low-Drift Voltage Reference Internal Oscillator Internal PGA: up to x16 12C Interface: 4-Pin-Selectable Addresses Four Single-Ended or 2 Differential inputs Programmable Comparator Wiring: Power First connect VDD and GND. These boards will work with either a 3.3v or a 5v supply. The absolute maximum analog input voltage is VDD + 0.3v. To avoid damage to the chip, do not attempt to measure voltages greater than VDD. I2C Connections I2C requires just 2 pins to communicate. These can be shared with other l2C devices. connect SDA->SDA and SCL->SCL. package contain： 4pcs ADS1115 I2C IIC Analog-to-Digital Converter

• Wide Voltage Supply Range: 2.0V to 5.5V, operate in a comparator mode which is helpful for maintaining accuracy.
• Low current consumption: the supply current of these digital converters are 150 µA, automatically powers down after a conversion and nicely reduces current consumption during idle,onboard reference and oscillator.
• Programmable data rate: 8sps-860sps,transferred via an I2C-compatible serial interface; Integrated programmable comparators simplify system monitoring.
• The ADS1115 is measured at high resolution and has an input multiplexer (MUX) that provides two programmble conparator differentials or four single-ended input; Four single-ended or ±256mV, allowing both large and small signals to be the differential input, for a variety of measurement and control applications.
• Especially a good tool for Pi, there is no analog GPIO pin; Easy to use I2C ADC Converter, with Programmable Gain Amplifier.
