Data Acquisition - Analog to Digital Converters (ADC)

Analog-to-Digital Converters (ADCs) are devices that are used to convert analog signals into digital representation. Specifically, the ADS54J64IRMP is a high-speed, precision, 12-bit ADCs. It has two differential inputs: a differential input for minimum-noise conversion and a complementary data output for serial interface to digital signal processors.

Application fields for the ADS54J64IRMP include automotive test and measurement, factory and process automation, optical sensors, CCD cameras, audio, and serial digital interface. In automotive applications the converter can be used to measure the voltage level of sensors, transducers and actuators. In factory and process automation it is often used to measure control loop signals, and in audio applications it can be used as a digital audio equalizer.

The working principle behind the ADS54J64IRMP is relatively simple. The input analog signal is first amplified, filtered, and then multiplexed by a switching unit. The device then uses a sampling-type analog-to-digital converter to convert the multiplexed signals into a 12-bit digital output. The output is then presented in the parallel or serial interface.

The ADS54J64IRMP is a low power device which requires 5.2V supply voltage, and is capable of operating at up to 100 MHz sampling frequency. The device is also equipped with a built-in temperature compensated reference that provides excellent stability over temperature in combination with an on-chip input buffer. This makes the ADS54J64IRMP a great choice for applications that require ultra-low noise and high precision data conversion.
