ADS7953EVM is an evaluation module of Texas Instruments’ low power, 8-channel, 16/12-bit, Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC). It features a power consumption of typically 200 μA at 5V and a sampling speed of up to 1 MHz. The evaluation module also includes connectors and switches for testing the ADC. Desiged for measuring various sensor and signal inputs, this evaluation module provides a versatile tool for design engineers, enabling them to quickly and easily evaluate the performance and features of the ADS7953.

The evaluation board of ADS7953EVM is designed to enable easy connection of various sensors and signals. It is equipped with 8 analog inputs, one 5V analog reference input, a 2.5V reference voltage for input buffer and a 3V3 reference voltage for digital core. The evaluation board has a socket for an ADS7953 device, and also has feature support for a separate ADS7952 device, if required. All analog and digital signals are displayed on the evaluation board. Two 8-bit DIP switches are provided for configuration of the device and various test conditions.

The working principle of ADS7953EVM involves taking the analog input signals and converting them into a digital representation. It uses a SAR ADC, which is a highly accurate and low-power device. The SAR ADC works by successively approximating the analog input and comparing the resulting digital code to a reference value until the lowest error is achieved. The ADC also supports a wide range of input sampling speeds and a wide range of voltage and temperature ranges.
