ADS7844EB Description

Short technical summary and product information.

The ADS7844EB is a 12-bit, 8-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It supports up to 8 single-ended or 4 differential input channels and offers a maximum conversion rate of 200 ksps. The device uses an SPI serial interface for data transfer and operates from a single 2.7V to 5.25V analog supply, with a separate digital supply range of 1.9V to 5.5V.

 

Key electrical characteristics include a typical power consumption of 1.8 mW, a signal-to-noise ratio (SNR) of 73.1 dB, and a SINAD of 72 dB. The ADC guarantees no missing codes and features ±1 LSB maximum INL and DNL. The reference voltage is external, allowing an input voltage range of 0V to VREF.

 

The ADS7844EB is housed in a 20-lead SSOP package (0.154" width, 3.90 mm) and is surface mount compatible. It is designed for use in data acquisition, test and measurement, industrial process control, personal digital assistants, and battery-powered systems. The operating temperature range is -40°C to 85°C.
