Analog to digital converters (ADCs) are electronic devices used in both commercial and consumer applications to generate digital representations of analog signals. The Texas Instruments\' ADS7853EVM-PDK is an evaluation board designed to provide system architects with an easy-to-use, off-the-shelf way to evaluate the characteristics and performance of the ADS7853, a high-resolution 12-bit ADC with an integrated voltage reference and low-power standby mode.This evaluation kit includes several components that work together to allow for constructing a system that is designed to measure a wide range of variables from different sources in a variety of applications, such as industrial process control, healthcare, automotive, aerospace, and consumer electronics. The ADS7853EVM-PDK evaluation board is a complete system utilizing the ADS7853 and the LM385 voltage reference.The ADS7853 is an integrated analog front-end (AFE) for high-resolution data acquisition applications. It features ±20nV of integral nonlinearity (INL) vs. temperature, a differentially-preamplified 12-bit pipeline, and a two-channel input multiplexer that supports both single-ended and differential inputs. It uses a 0.2V reference, which allows it to achieve a maximum sampling rate up to 250MSPS. The ADS7853EVM-PDK is designed to offer performance across the range of sampling frequencies and input voltages.The evaluation board includes a 16-bit Serial Peripheral Interface (SPI) for minimizing the external component count, and the included SDK makes it easy to use the board in a variety of design scenarios. It also includes power, RESET, and Connectivity Test & Programming Interfaces. The LM385 is an ultra-low-power, precision voltage reference with an output accuracy of 0.2%. It is powered by an external Vcc and provides a constant absolute accuracy over a wide range of input supply and temperature conditions.The ADS7853EVM-PDK also has an onboard oscilloscope that allows designers to easily test and debug the board. An analog voltage input and analog-to-digital converter enable viewing the input, output, and digitizations of the board. The oscilloscope\'s input can be configured to either measure the signal at the ADC input or measure the signal on the reference input in order to view the signal resolution and denote the settling time of the signal.The ADS7853EVM-PDK features several power-saving modes that allow the user to achieve a portion of the performance with minimum power usage. Upon entering the standby mode, the ADS7853 goes to a low-power state in order to reduce power usages and increase battery life. In a similar way, the LM385 can be put into an inactive state when not in use, as it consumes only 10 µA of current even while in use.In summary, the ADS7853EVM-PDK is an easy-to-use evaluation board for system architects to evaluate the performance of the Texas Instruments ADS7853, a high-resolution 12-bit ADC with an integrated voltage reference and low-power standby mode. It features integrated components and is designed to offer performance across the range of sampling frequencies and input voltages. This evaluation board also includes an onboard oscilloscope, multiple power-saving modes, and an SDK for ease of use.
