ADS7844N/1K Description

Short technical summary and product information.

The ADS7844N/1K is a 12-bit, 8-channel SAR ADC from Texas Instruments designed for precision data acquisition. It features a multiplexed input configuration that supports 8 single-ended or 4 differential channels. The device uses an external reference and achieves a sampling rate of 200 ksps with typical power consumption of only 1.8 mW at 5V. The analog supply voltage range is 2.7V to 5.25V, while the digital supply ranges from 1.9V to 5.5V, allowing flexible system integration. Key performance metrics include a signal-to-noise ratio (SNR) of 73.1 dB, SINAD of 72 dB, and integral/differential nonlinearity of ±1 LSB maximum with no missing codes. The SPI serial interface simplifies connection to microcontrollers and DSPs. The device is available in a 20-lead SSOP package (0.209", 5.30mm width) for surface-mount assembly. Operating temperature range is -40°C to 85°C. Typical applications include data acquisition systems, industrial process control, test and measurement equipment, personal digital assistants, and battery-powered systems. The ADS7844 is also an alternate source for the Maxim MAX147.
