ARCELI 16 Bit 16 Byte 4 Channel I2C IIC Analog-Digital ADC PGA Converter with Programmable Gain Amplifier High Precision ADC Converter Development Board for Arduino Raspberry Pi
Description: For microcontrollers without analog-to-digital converters or if you want an ADC with higher accuracy, it provides 16-bit accuracy with 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels or two differential channels. As a nice bonus, it even includes a programmable gain amplifier (up to x16) that helps amplify smaller single/differential signals across the entire range. The chip is quite small, so it comes on a breakout board with ferrites to keep AVDD and AGND quiet. The interface is via I2C. Simply connect GND to ground, VDD to your logic power supply and SCL/SDA to the I2C port of your microcontroller, and run the sample code to start reading data. Parameters: ADC bit rate: 16 bit Interface type: I2C Channels: 4 channel AN0 AN1 AN2 AN3 Input voltage: 2.0 V - 5.5 V. Channel input voltage: 0-VDD Continuous mode: only 150μA. Single shot mode: automatic shutdown. Programmable data rate: 8sps-860sps. Input range programmed control, 7 types input areas: -0.256 V ~ + 0.256 V, -0.512 V ~ + 0.512 V, -1.024 V ~ + 1.024 V, 2.048 V ~ + 2.048 V, -4.096 V ~ + 4.096 V, -6.14 V. 4 V ~ + 6.144 V I2C 7- bit addresses between 0x48-0x4B. Box contents: 1 x 16-bit 4-channel analogue-to-digital ADC converter. 1 x pin header
