Texas Instruments' ADS7041 and ADS7044 are 10-bit/12-bit, 1 MSPS, analog-to-digital converters (ADC). These devices support a wide analog input voltage range (1.8 - 3.6 V) and includes a capacitor-based, successive-approximation register (SAR) ADC with an inherent sample-and-hold circuit. 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. These devices support a wide digital supply range (1.65 - 3.6 V), enabling direct interface to a variety of host controllers. They comply with the JESD8-7A standard for a normal DVDD range (1.65 - 1.95 V).
The ADS7041/44 are available in 8-pin, miniature, leaded, and X2QFN packages and is specified for operation from –40°C to 125°C. Miniature form-factor and extremely low-power consumption make this device suitable for space-constrained, battery-powered applications.
