The SAR architecture gives you a deterministic conversion time — no pipeline delay, so the sample you request is the sample you get, cycle after cycle. No separate AVDD and DVDD rails to route. The SPI-compatible serial interface (Data Interface: SPI) talks directly to most microcontrollers without glue logic. The conversion result shifts out on SCLK edges; the host reads it over three wires (SCLK, CS, DOUT). ## Industrial temperature range and SOIC package The 1.27 mm pin pitch leaves room for a guard ring around the analog input if you need it. ## Active production and compliance status The reference type is selectable: use the internal 2.5 V bandgap for a stand-alone design, or drive REF with an external precision reference when you need tighter absolute accuracy across temperature.","metaTitle":"MAX1240AESA+ ADC, 12-Bit SAR, 73k SPS, 8-SOIC","metaDescription":"MAX1240AESA+ 12-bit SAR ADC, 73k samples/sec, single-ended input, SPI interface, 2.7-3.6V supply, -40 to +85°C, 8-SOIC.
