The DC1620A-S from Maxim Integrated is an evaluation board designed to test the performance of analog-to-digital converters (ADCs). It supports the functionality of a single-ended/differential high speed, SAR-based ADC. This evaluation board design contains two separate evaluation boards and includes the DC1624A-S analog input connector board and the DC1620A-S digital converter evaluation board. The analog input connector board supports up to 8-channel analog input signals and protects valuable equipment from input over-voltage and under-voltage. The DC1620A-S board includes the MAX1462 single-ended/differential 8-bit SAR ADC, which is ideal for applications requiring high speed, low power, and high accuracy. This evaluation board is perfect for a wide variety of applications such as industrial automation and process control, audio and video processing, automotive control systems, medical imaging, consumer electronics, and communication systems.

The DC1620A-S evaluation board offers a complete application solution. It is equipped with an on-board system controller with an embedded 8051 microcontroller, a 12-bit SAR ADC interface, and multiple peripheral circuits. The controller is compatible with Maxim’s System Support Library, which allows the user to control and evaluate the ADC’s performance. It also provides a USB interface for Windows-based PC communication and programming. The evaluation board operates at voltage range of 3.3V to 12V and is RoHS compliant. The board includes a configuration switch to select either single-ended or differential mode. The board is also compatible with the DC6130I-S high speed signal conditioning board.

The DC1620A-S evaluation board is designed to enable the evaluation and testing of the performance of the MAX1462 ADC. The board utilizes a multi-phase clocked capacitor array structure to generate a sampling clock with a high precision. The board also incorporates an adjustable reference voltage source, which improves the accuracy and linearity of each individual conversion cycle. The evaluation board includes an on-board low-pass filter, a digital sequencer, and a 4-digit LED display. The display shows the values of the ADC, which can be used to visually evaluate the converters performance. The evaluation board also supports a variety of digital data formats, including parallel, multiplexer compatible, binary, and hexadecimal data. In addition, the evaluation board can be configured to support a variety of output frequencies. The DC1620A-S board includes an on-board memory device, which makes it simpler to store and access data.

The MAX1462 comprises of a full-speed, 8-bit ADC with a maximum conversion rate of 8MSPS. It is available in a 7mm x 7mm LFCSP package and requires only a 1.8V analog supply and a single 3.3V digital supply. The DC1620A-S evaluation board includes an on-board power supply, which can supply the required voltage and current levels. The MAX1462 is very energy efficient and consumes only 20mW of power per channel. The ADC has a high SNR of 76.9dB and a input noise floor of -138dBVrms.

The DC1620A-S evaluation board is a great tool to evaluate and test the performance of the MAX1462 ADC in a wide variety of applications. It is designed to work with a variety of input signals and data formats. The board supports a variety of control and evaluation features, including an adjustable reference voltage source, a multi-phase clocked capacitor array, a digital sequencer, and an LCD display.
