ADS7844E Description

Short technical summary and product information.

The ADS7844E is a 12-bit, 8-channel sampling analog-to-digital converter (ADC) from Texas Instruments. It uses a successive approximation register (SAR) architecture and offers a maximum conversion rate of 200 ksps. The device can be configured for 8 single-ended inputs or 4 differential inputs, providing flexibility for various measurement applications. It operates from a single supply voltage of 2.7V to 5.25V and has a typical power consumption of 1.8 mW at 200 ksps. The reference voltage can be set externally between 100 mV and VCC, allowing a corresponding input voltage range of 0V to VREF. Key performance specifications include 73.1 dB SNR, 72 dB SINAD, and ±1 LSB INL/DNL. The ADS7844E is available in a 20-lead SSOP package and is qualified for industrial temperature range (-40°C to 85°C). It is well-suited for data acquisition, test and measurement, industrial process control, and battery-powered systems.
