Analog to digital converter optimized for low-power operation

04-03-2015 | Mouser Electronics | Semiconductors

Mouser is now stocking the Texas Instruments (TI) ADS8339 successive-approximation register (SAR) analog to digital converter (ADC). Optimized for low-power operation, where power consumption scales directly with speed, the ADS8339 is a miniature, micro-power, 16-bit ADC that dissipates only 17.5mW at a sampling rate of 250KHz, and only 0.25µW in power-down state. The ADS8339 integrates sample-and-hold and operates with a 2.25V to 5.5V external reference. The ADS8339 provides a unipolar single-ended input range from 0V to VREF. The device offers zero latency at full speed, and uses an internal clock for conversion. Applications include process controls, battery-powered equipment, data acquisition systems, medical electronics and optical networking systems. The surface-mount ADS8339 operates from -40C to +85C, and is housed in a miniature VSSOP 10-pin package with a 3mm x 3mm nominal body size. The ADS8339 is also supported by an evaluation module - the 595-ADS8339EVM-PDK.
