The ADS7844NB is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It is designed for 8-channel single-ended or 4-channel differential input configurations, with a maximum sampling rate of 200 ksps. The device uses an external reference and provides a serial SPI interface for data transfer.
Key electrical specifications include a typical signal-to-noise ratio (SNR) of 73.1 dB, signal-to-noise plus distortion (SINAD) of 72 dB, and integral non-linearity (INL) and differential non-linearity (DNL) of ±1 LSB maximum. The analog supply voltage range is 2.7V to 5.25V, and the digital supply voltage range is 1.9V to 5.5V. Typical power consumption is 1.8 mW.
The device is housed in a 20-lead SSOP package with a width of 5.30 mm, suitable for surface mount assembly. The operating temperature range is -40°C to 85°C. The ADS7844 includes a shutdown mode that reduces power dissipation to under 1 µW. It is specified for data acquisition, test and measurement, industrial process control, personal digital assistants, and battery-powered systems.
