Quality Control: Learn More
Texas Instruments ADS7844NB is a 12-bit successive approximation register (SAR) Analog-to-Digital Converter (ADC) designed for high-performance applications. This component features 4 or 8 selectable input channels with a multiplexer (MUX), sample-and-hold (S/H) circuit, and a 12-bit ADC. The data interface is SPI, enabling efficient communication with microcontrollers. It supports both single-ended and differential input types and requires an external reference voltage. Operating within a temperature range of -40°C to 85°C, the ADS7844NB is available in a 20-SSOP package suitable for surface mounting. Analog and digital supply voltages can range from 2.7V to 3.6V or 5V. This ADC is frequently utilized in industrial automation, medical equipment, and data acquisition systems.
