Texas Instruments 16-bit ADS8339 low-power ADC at MouserMouser Electronics Inc. is now stocking the ADS8339 Low Power ADCs from Texas Instruments. Optimised for low-power operation, where power consumption scales directly with speed, the ADS8339 is a miniature, micro-power, 16-bit analogue-to-digital converter (ADC) that dissipates only 17.5mW at a sampling rate of 250KHz, and only 0.25uW 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 suitable for low-power ADC applications.

The Texas Instruments ADS8339 Low Power ADC 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 optimised. Fully optimised, the ADS8339 is capable of 93.6dB SNR (typ) and –106dB THD (typ) at a 10kHz input, with +/-2.0 LSB INL (max) and +/-1.0 LSB DNL (max). Low-power dissipation of the devices is rated at 17.5mW (typ) at 250 kSPS.

Texas Instruments’ ADS8339 Low Power ADCs support three serial interface options, including a 25-MHz, SPI-compatible serial interface that easily interfaces to microcontrollers, DSPs, or FPGAs.

Targeted for lower-speed applications, Texas Instruments’ ADS8339 Low Power ADCs are well suited for instrumentation and process controls, battery-powered equipment, data acquisition systems, medical electronics and optical networking systems.

The ADS8339 operates from -40degC to +85degC, is offered in an SMD/SMT mounting style, and is available today through Mouser Electronics in a miniature VSSOP 10-pin package with a 3mm × 3mm nominal body size. The ADS8339 is also supported by an evaluation module – the 595-ADS8339EVM-PDK – also available for purchase through the Mouser Electronics website. To learn more, visit
