[{"content":" ADC Add-on Board Request a quote The Ikainex ADC add-on board is designed for precision analog-to-digital conversion. Powered by Microchip's MCP3204 12-bit SAR ADC, it offers a 4-channel single-ended setup with a fast 100 ksps sampling rate and an SPI-compatible interface. Ideal for industrial monitoring, instrumentation, and remote data acquisition systems. Resolution 12-bit Channels 4 (single-ended) Sample Rate 100 ksps Interface SPI Key Features 12-Bit 4-Channel ADC — Driven by the Microchip MCP3204, supporting up to four single-ended input channels (CH0–CH3). Onboard Signal Buffering — Every analog input passes through a Microchip MCP6284 5MHz rail-to-rail op-amp for optimal signal conditioning before conversion. Flexible Reference Selection — Easily switch the reference voltage using the onboard REFERENCE jumper between VCC (3.3V/5V) or an ultra-stable 4.096V provided by the onboard Microchip MCP1541 voltage reference. 4-Wire SPI Communication — Supports standard SPI modes (0 and 3) at clock speeds up to 2 MHz, activated via a low CS line. Dual Logic Voltage Support — Integrated PWR SEL jumper enables seamless operation with both 3.3V and 5V host microcontrollers. Convenient Connectivity — Dedicated CH0–3 terminal blocks with twin GND connections simplify external analog sensor integration.
