Product details

10-bit SAR ADC with SPI and on-chip temperature sensor

The Maxim Integrated MAX1031BCTI+ is a 10-bit successive-approximation (SAR) analog-to-digital converter that samples at 300k samples per second over an SPI interface. 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.

Frequently asked questions

Does MAX1031BCTI+ include an internal reference?

Yes, the MAX1031BCTI+ supports both external and internal reference types. The internal reference simplifies the BOM by eliminating an external voltage reference IC.
