The ADS7844N is a 12-bit, 8-channel sampling analog-to-digital converter (ADC) from Texas Instruments. It uses a successive approximation register (SAR) architecture and provides a maximum sampling rate of 200 ksps. The device offers 8 single-ended or 4 differential input channels via an internal multiplexer.
Key electrical specifications include a typical signal-to-noise ratio (SNR) of 73.1 dB and a SINAD of 72 dB. The ADC operates from a single analog supply voltage ranging from 2.7V to 5.25V and a digital supply from 1.9V to 5.5V. Typical power consumption is 1.8 mW at a 200 kHz throughput rate with a 5V supply. The reference voltage is external and can be set between 100 mV and Vcc, defining an input voltage range of 0V to Vref.
The ADS7844N is housed in a 20-SSOP package and is designed for surface mount assembly. It communicates via a synchronous serial interface (SPI). The device is specified for an operating temperature range of -40°C to 85°C.
