WM8952ECS/RV is a special purpose Data Acquisition technology used for both Analog-to-Digital (ADC) and Digital-to-Analog (DAC) Conversion. It is an efficient, low-power device that is suitable for portable and medical applications.

The WM8952ECS/RV is a precision integrated circuit (IC) providing an interface between digital and analog systems. The device includes a pipelined A/D converter, microprocessor control logic combined with temperature compensation, one programmable signal routing block, two 12-bit configurable analog switches and a signal conditioning system. The signal processing algorithms are highly customizable. The device offers three different signal outputs and the signal routing can easily be configured to suit the application.

The A/D conversion performance is improved by the device’s onboard temperature compensation. Additionally, the programmable signal routing block enables the signal to be routed to the required destination.

The main application of the WM8952ECS/RV is as a diagnostic tool for medical monitoring systems. It can be used to measure electrical activity and other physiological signals from patients. The device is also suitable for use in portable instruments and other systems that require low-power, high accuracy signal conditioning over a wide range of frequencies.

The working principle of the device is based on a pipelined A/D conversion process. This process involves several stages such as sampling, analog signal conditioning, signal conversion and digital signal conditioning.

Thesampling stageuses a high-speed pipeline to capture the incoming signal. This signal is then fed into the analog signal conditioning stage which performs operations such as amplification, filtering and offset correction on the analog signal. The signal is then converted into a digital form by an analog-to-digital converter. The output is then subject to additional digital signal conditioning via the programmable signal routing block.

The programmable signal routing block includes two 12-bit configurable analog switches which can be programmed to route the analog signal to the appropriate destination. This enables a highly flexible signal conditioning system. For medical applications, this system can be used to route the signal to multiple destinations such as a patient monitor, EKG machine or other medical device.

The WM8952ECS/RV is a powerful and versatile data acquisition device which is suitable for a variety of applications. Its low-power consumption and high accuracy make it an ideal choice for portable instruments and medical monitoring systems.
