Low-power ADCs extend battery life

Sunnyvale, Calif.—Broadening its portfolio of 12-/10-/8-bit A/D converters (ADCs), Maxim Integrated Products has introduced the MAX11102 family of low-power ADCs.

This family consists of nine devices available in different resolution (12-/10-/8-bit), channel-count (2/1), and conversion-rate (3/2Msps) configurations. Designed to extend battery life in portable electronics, the devices offer a maximum power consumption of 9.9mW, which is 32% lower than the competition, according to Maxim. Additionally, they are the only ADCs in this class able to operate from a supply rail down to 2.2V, the company added.

Fast wake-up and shutdown times enable the ADCs to operate in burst mode, which minimizes the amount of time spent in active power mode. These ADCs are well-suited for portable/battery-powered electronics, automotive designs, solar-powered systems, and system-monitoring applications.

Providing power savings without compromising performance, this family of ADCs yields a worst-case SNR of 70.5dB and SINAD of 70dB. The digital interface operates from 1.5V to 3.6V, allowing direct connection to a wide range of SPI-based host devices without a level shifter.

Pin-for-pin compatibility between devices allows designers to change resolution without redesigning their board or control software. Refer to the selector table for additional information.

All devices are fully specified for operation over the -40°C to +125°C automotive temperature range.

Pricing: Starts at $0.85 (1000-up, FOB USA).
