The DC873A is an Analog-to-Digital Converter Evaluation Board from Texas Instruments, which allows users to evaluate the performance of A/D converters. This board is designed to allow the evaluation of various analog-to-digital converter chips and to measure the performance of these converters. The board supports a wide variety of chips from the TI ADC family, including the ADS8325 (16-bit, 500 KSPS), ADS8356 (24-bit, 320 KSPS), and ADS8344 (20-bit, 500 KSPS) ADC chips.

The DC873A comes with the necessary components to quickly evaluate the performance of various ADC chips. The board features two inputs that can be used for analog signals from -5 to +5 V. There are multiple gain channels, allowing for an adjustable gain level of up to +5V or -2.5V. The board also includes an SPI connection for controlling the ADC chip, as well as two connectors for quickly measuring and comparing the performance of different chips.

The board supports both single-ended and differential inputs. Single-ended inputs are routed directly into the board, while differential inputs are routed through the separate analog channel selector. The board also features multiple outputs, allowing for the evaluation of both single-ended and differential output signals. Several trigger signals are provided, enabling users to set up different test scenarios and measure the performance of the ADC accordingly.

The DC873A also includes various features that make prototyping and test applications easier. An adjustable offset of up to +2.5V or -5V is included, allowing users to quickly adjust the input value range. The board also includes a C-style connector for direct connection to the ADC chip, allowing users to quickly evaluate different chips without the need for any additional setup. Additionally, an external clock frequency of up to 50 MHz is supported, allowing for faster sampling rates.

Overall, the DC873A provides a versatile platform for evaluating and testing different ADC chips. It features multiple input and output channels, adjustable gain levels, and numerous trigger signals, allowing users to quickly set up various test scenarios. Additionally, the board also makes prototyping applications easier, with its adjustable offset and C-style connector for quickly connecting the chip to the board. With its numerous features and robust design, the DC873A is the ideal tool for quickly evaluating the performance of various ADC chips.
