8-bit SAR ADC with 500k SPS and SPI interface
The Maxim Integrated MAX11662AUB+ is an 8-bit successive-approximation-register (SAR) analog-to-digital converter that samples at 500k samples per second. It accepts two single-ended inputs through a 1:1 S/H-ADC configuration and communicates over an SPI data interface. The device operates from a single 2.2V to 3.6V supply for both analog and digital rails, simplifying power distribution in mixed-signal designs. Housed in a 10-uMAX-EP package (3.00mm width, exposed pad), it is rated for the full industrial temperature range of -40°C to +125°C, making it suitable for sensor interfaces, data acquisition modules, and control-loop feedback in thermally demanding environments.
The surface-mount footprint is compact at 3.00mm width, suitable for space-constrained layouts.
