The ADS7056 is a 14-bit, 2.5-MSPS, analog-to-digital converter (ADC). The device includes a capacitor-based, successive-approximation register (SAR) ADC that supports a wide analog input voltage range (0 V to AVDD, for AVDD in the range of 2.35 V to 3.6 V).
The SPI-compatible serial interface is controlled by the CS and SCLK signals. The input signal is sampled with the CS falling edge and SCLK is used for conversion and serial data output. The device supports a wide digital supply range (1.65 V to 3.6 V), enabling direct interfacing to a variety of host controllers. The ADS7056 complies with the JESD8-7A standard for a normal DVDD range (1.65 V to 1.95 V).
The ADS7056 is available in an 8-pin, miniature, X2QFN package and is specified over the extended industrial temperature range (–40°C to +125°C). Miniature form-factor and extremely low-power consumption make this device suitable for space-constrained and battery-powered applications.
