Mouser 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.
