Data Acquisition has long been a cornerstone of automated systems, providing the necessary capabilities for robust control of complex systems. The Digital to Analog Converter (DAC) and Analog to Digital Converter (ADC) are two critical components of data acquisition, and the PCM1717E/2K Special Purpose ADC/DAC is a great choice for engineered designs. This article will discuss the application areas for the PCM1717E/2K and document its working principles.

The PCM1717E/2K is a bipolar mixed-signal data converter that integrates two 8-bit converters on a single monolithic integrated circuit. The PCM1717E/2K can be used in a variety of applications such as digital signal processing, image processing, video processing, voice recognition, automotive control, robotics, industrial control, medical equipment, and temperature control. The device has a wide operating temperature range of -40° C to +85° C and a low power consumption of 9 mW at 3V. The PCM1717E/2K features powerful software with a built-in Trigger Code that can be used to set up the clock and data conversion speed, as well as a built-in Wait Timer for accurate analog measurements.

The PCM1717E/2K is a true two-wire, two-way interface that eliminates the need for additional clock lines or control lines. It has a linear or differential analog input (A/D) voltage range from -12V to +12V, with a resolution of ± 1.25V (linear) or ± 0.625V (differential). The output voltage is stable and highly immune to power supply glitches and transient output disturbances. The device also features a programmable gain and offset adjustment from 0.35 to 10.0, allowing users to linearize wide input voltage ranges. The digital outputs are TTL/CMOS compatible.

The PCM1717E/2K has several features designed to ensure consistent and reliable operation. The analog input stage is designed to reject unwanted noise and to prevent the device from saturating. The thermal sensor provides temperature compensation, which allows the device to compensate for variations in the input voltage close to the signal and noise limits. The device also features integrated over-shoot and under-shoot protection, as well as automatic zero and full-scale calibration capabilities.

The PCM1717E/2K is an easy-to-program device that can be programmed either from the operator panel or from a Windows-compatible application. The programming parameters are stored in an external non-volatile memory. The device can also be programmed by remote control, for use in \'headless\' applications.

The functionality of the PCM1717E/2K makes it an excellent choice for demanding engineered applications. Its wide power supply range, low power consumption, and on-chip trigger code make it suitable for a variety of applications. Its highly accurate analog-to-digital and digital-to-analog converters, as well as its integrated over-shoot and under-shoot protection and auto-calibration capabilities, make it a reliable and efficient solution for data acquisition.
