DC918C-C Application Field and Working PrincipleThe DC918C-C is an evaluation board for analog-to-digital (A/D) converters. It is part of series C of the DC918C boards, a family of integrated circuits commonly employed in data converters and processing applications. The DC918C-C board features the latest in A/D converter technology, offering superior speed and accuracy. The board allows designers to prototype and develop applications that utilize analog-to-digital converters with greater efficiency. This article will provide an overview of the board’s application field and discuss how the board works.Application FieldThe DC918C-C is ideal for a wide varietyof applications. It may be used in audio recording, signal processing, and data acquisition applications. It can also be used to interface analog sensors with digital control systems, and to display analog signals on digital displays. Additionally, the board can be used for digital signal processing applications, including automatic control systems, and for medical and industrial instrumentation.Working PrincipleThe DC918C-C board is equipped with two A/D converters, providing conversion of 12- and 16-bit data. In addition, two analog input channels are provided, with programmable gain and offset. The board includes micro-controllers, on-board digital signal processor (DSP) core, communications peripherals, and power management.The board features an A/D converter with integrated low-noise, high-accuracy sample and hold circuitry. The A/D converter operates with a sampling rate of up to 4 MS/s, and it is capable of conversions ranging from 80 dB of offset to 25 HB of noise. The board utilizes a unique charge-pump architecture that allows for both a single-ended analog voltage and a differential analog voltage to be converted in the same device.The board also utilizes Digital Pre-distortion (DPD) to reduce the errors inherent in ADC systems. DPD cancels out non-linear components in signals that are normally caused by non-idealities in the signal chain. This technique allows for linear conversion of signals even in extreme high-frequency applications. The board also features off-chip digital signal conditioning (DSC) for further control of non-linearities.In addition, the DC918C-C board incorporates sophisticated control and power management features. It is equipped with a programmable reference voltage generator, a programmable logic voltage regulator, and an on-board temperature monitor. The board also has programmable logic level switching control and is capable of providing logic-level power to external logic chips.ConclusionThe DC918C-C board is a versatile integrated circuit used for analog-to-digital conversion. Its key features include two A/D converters, micro-controllers, on-board DSP core, communications peripherals, power management, and DPD and DSC capabilities. These features allow the DC918C-C to be used in a variety of audio recording, signal processing, and data acquisition applications. The board’s overall performance and low cost make it an excellent choice for prototyping and developing analog-to-digital converter applications.
