Texas Instruments 16-bit ADS8339 Low Power ADC Now at Mouser

by donpedro

Mouser Electronics, Inc. is now stocking the ADS8339 Low Power ADCs from Texas Instruments. Optimized for low power operation, where power consumption scales

directly with speed, the ADS8339 is a miniature, micro-power, 16-bit analog-to-digital converter (ADC) that dissipates only 17.5mW at a sampling rate of 250KHz, and only 0.25µW in power-down state. The ADS8339 is a successive-approximation register (SAR) ADC with an integrated sample-and-hold. The high performance and low power dissipation of these devices makes them ideal for low-power ADC applications.
The Texas Instruments ADS8339 Low Power ADC, available from Mouser Electronics, is a single-channel ADC that 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. The capacitor-based SAR ADC on the ADS8339 is based on a charge redistribution architecture, which inherently includes a sample-and-hold function. To obtain the best SAR performance, the reference driver and the input driver circuit must be optimized. Fully optimized, the ADS8339 is capable of 93.6 dB SNR (typ) and –106 dB THD (typ) at a 10-kHz input, with ±2.0 LSB INL (max) and ±1.0 LSB DNL (max). Low power dissipation of the devices is rated at 17.5 mW (typ) at 250 kSPS.
