It accepts up to 8 differential or 16 single-ended inputs through an internal multiplexer, with a 1:1 S/H-to-ADC ratio. The part includes an on-chip temperature sensor, usable for cold-junction compensation or die-temperature monitoring. Supply range is 2.7 V to 3.6 V for both analog and digital rails. Reference can be external or internal. Housed in a 28-TQFN (5x5 mm) package, it operates over 0°C to 70°C. ## Active lifecycle, no obsolescence concern The MAX1031BCTI+ carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"Maxim MAX1031BCTI+ 10-bit SAR ADC, 300k SPS, 28-TQFN","metaDescription":"Maxim MAX1031BCTI+ 10-bit SAR ADC, 300k samples/sec, SPI, 8/16 ch, internal temp sensor, 2.7-3.6V, 28-TQFN.
