3 Description
The ADS8339 is a 16-bit, 250-kSPS, analog-to-digital
converter (ADC). The device operates with a 2.25-V 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 daisyChain
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.
