ADS8339 Miniature SAR ADC

Texas Instruments' ADS8339 16-bit, 250 kSPS, serial interface, micro-power, miniature, SAR analog-to-digital converter

Image of Texas Instruments ADS8339 Miniature SAR ADCTexas Instruments' ADS8339 is a 16-bit, 250 kSPS, analog-to-digital converter (ADC). The device operates with a 2.25 to 5.5 V external reference. The device includes a capacitor-based, successive-approximation register (SAR) ADC with an inherent sample-and-hold circuit.

The device includes a 25 MHz, SPI-compatible serial interface. The interface is designed to support daisy-chaining or cascading of multiple devices. Furthermore, a busy indicator makes synchronizing with the digital host easy. The unipolar, single-ended input range for the device supports an input swing of 0 V to VREF.

The device is optimized for low-power operation and power consumption scales directly with speed. This feature makes the device attractive for lower speed applications. The ADS8339 is available in a VSSOP-10 package.
