The SPI interface clocks out the conversion result at up to 20 MHz typical, so the host MCU reads one 14-bit word in under 1 µs. The 1:1 S/H-to-ADC ratio means no pipeline delay; the sample is held and converted in one cycle. ## Differential input and supply rails The differential input rejects common-mode noise from the sensor ground — critical when the analog front-end sits on a separate ground plane from the digital core. The external reference sets the full-scale range; a clean 1.8 V reference keeps the LSB size at 110 µV. ## Industrial temperature range and deployment context The 10-MSOP package is surface-mount, so the board sees the same thermal cycle as the ADC; no special handling beyond standard reflow profiles.","metaTitle":"MCP33121D-10-I/MS ADC 14-bit 1 MSPS SAR 10-MSOP","metaDescription":"Microchip MCP33121D-10-I/MS 14-bit SAR ADC, 1 MSPS, differential input, SPI, 10-MSOP.
