Texas Instruments 16-bit ADS8339 low power ADC now at Mouser

Mouser Electronics, the global authorised distributor with the newest semiconductors and electronic components, 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 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 optimised. Fully optimised, 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.

The 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 perfectly suited for instrumentation and process controls, battery-powered equipment, data acquisition systems, medical electronics and optical networking systems.

The ADS8339 operates from -40 °C to +85 °C, 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 x 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.
