Microchip Technology, Inc. Data Acquisition - Data Acquisition - Analog to Digital Converters (ADC) - MCP3424-E/ST MCP3424-E/ST

The MCP3424-E/ST is an 18-bit delta-sigma analog-to-digital converter (ADC) featuring four differential input channels and an I¬=C interface. It operates within a voltage range of 2.7V to 5.5V and supports programmable gain settings of 1, 2, 4, or 8, allowing for high-resolution conversion of weak input signals. The device includes an on-board voltage reference of 2.048V with an accuracy of ¬±0.05% and a drift of 15 ppm/¬8C. It offers multiple data rate options, including 3.75 SPS at 18 bits, 15 SPS at 16 bits, 60 SPS at 14 bits, and 240 SPS at 12 bits, with both one-shot and continuous conversion modes available. The MCP3424 is designed for low current consumption, typically 135 ¬µA in continuous mode and 36 ¬µA in one-shot mode. Its extended temperature range of -40¬8C to +125¬8C makes it suitable for various applications, including portable instrumentation, temperature sensing, and factory automation. The device is available in a 14-pin TSSOP package.
