Sampling at 133k samples per second, it delivers the throughput needed for industrial sensor acquisition, data-logging front ends, and battery-monitoring channels where 12-bit resolution is the sweet spot between cost and accuracy. The SPI digital interface keeps the pin count low and ties directly to most microcontrollers without glue logic. ## Industrial temperature range and package Rated for -40°C to 85°C, the MAX1203BEAP+ fits industrial enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics where the ambient can swing. The 20-pin SSOP (0.209\" body width, 5.30 mm) is a surface-mount footprint that saves board area compared to a wider SOIC, and the tube shipping medium is typical for prototype and low-to-mid volume builds. ## Sourcing and lifecycle For a BOM line that needs a 12-bit SAR ADC with SPI and a flexible input mux, the MAX1203BEAP+ is a safe choice for new designs and production ramp.","metaTitle":"MAX1203BEAP+ ADC 12-Bit SAR, 133k SPS, 20-SSOP","metaDescription":"MAX1203BEAP+ 12-bit SAR ADC from Analog Devices. 133k sampling rate, SPI interface, 4/8 inputs, differential/single-ended.
