2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 ADC 3 click 2 3 4. Essential features ADC3 click can be configured in different ways depending whether accuracy or speed is your primary concern. At the highest resolution of 16-bits, the chip outputs conversion results at 15 samples per second. At 14-bits, the sample rate is 60 SPS. Maximum conversion speed is achieved in 12-bit mode, 240 samples per second. The I2C interface also has standard, fast and Turn the board upside down so that Turn the board upward again. Make sure high speed modes. The chip automatically the bottom side is facing you upwards. to align the headers so that they are calibrates offset and gain errors. A built-in Place shorter pins of the header into the perpendicular to the board, then solder the gain amplifier allows you to convert weak appropriate soldering pads. pins carefully. signals (up to x8 amplification). 1. Introduction ADC3 click carries Microchips MCP3428 16- 3. Plugging the board in bit multichannel analog-to-digital converter. click The click has four pairs of screw terminals Once you have soldered the headers your onboard, letting you access the chips four board is ready to be placed into the desired BOARD differential input channels. A pair of onboard mikroBUS socket. Make sure to align the cut www.mikroe.com jumpers allow switching between different in the lower-right part of the board with the I2C addresses. ADC3 click communicates markings on the silkscreen at the mikroBUS with the target MCU through mikroBUS I2C socket. If all the pins are aligned ADC 3 click Manual v100 pins (SCL, SDA).
