Microchip Technology, Inc. Analog to Digital Converters (ADC) MCP3426A5T-E/MS

The MCP3426A5T-E/MS is a 16-bit Delta-Sigma Analog-to-Digital Converter (ADC) featuring two differential input channels and an I¬=C interface. It operates within a voltage range of 2.7V to 5.5V and supports programmable gain amplification with options of 1, 2, 4, or 8. The device includes an on-board voltage reference of 2.048V with an accuracy of ¬±0.05% and a drift of 15 ppm/¬8C, allowing for a full-scale differential input range of ¬±2.048V. This ADC offers multiple data rate configurations, including 15 samples per second (SPS) at 16 bits, 60 SPS at 14 bits, and 240 SPS at 12 bits. It features both one-shot and continuous conversion modes, enabling flexibility in power consumption, with typical current draws of 135 ¬µA during continuous operation and as low as 0.56 ¬µA in one-shot mode at 12 bits. The device is suitable for a variety of applications, including portable instrumentation, temperature sensing, and factory automation, and operates over an extended temperature range of -40¬8C to +125¬8C. The MCP3426A5T-E/MS is available in multiple package types, including MSOP and SOIC.
