Introduction

AI Translation

The ADS7044 is a 1MSPS ADC. The device supports a wide analog input voltage range (±1.65V to ±3.6V) and includes a capacitor-based SAR ADC with an integrated sample-and-hold circuit. The SPI-compatible serial interface is controlled by CS and SCLK signals. The input signal is sampled on the falling edge of CS, while SCLK is used for conversion and serial data output. The device supports a wide digital supply range (1.65V to 3.6V), enabling direct connection to various host controllers. The device complies with the nominal DVDD range (1.65V to 1.95V) per the JESD8-7A standard. The device is available in an 8-pin miniature X2QFN package with a rated operating temperature range of -40°C to 125°C. Its compact size and ultra-low power consumption make it ideal for space-constrained, battery-powered applications.
