Introduction

The PCM1864DBTR is a high-speed, low-power CMOS device used for data acquisition. It consists of a highly integrated analog front end (AFE) with an Analog to Digital Converter (ADC), Digital to Analog Converter (DAC), and Digital interfaces. The ADC and DAC have 16-bit sampling and can operate at data rates up to 5 megasamples per second (MSPS). The PCM1864DBTR also features a wide input range of 6.25 to 3.2V and operates over the industrial temperature range from -40 to +85°C.

Application Field

The PCM1864DBTR is often used for audio and video applications such as speech recognition, video surveillance and digital audio processing. Because of its high-speed, low-power and wide input range it’s also often used in a variety of medical, automotive, and industrial automation data acquisition applications.

The PCM1864DBTR is ideal for applications where size and power consumption are critical. It uses less than 380 mW of power at 5 MSPS and its 7 × 7 mm package size saves a significant amount of board space. Its wide-input range and two differential inputs also make it ideal for single-ended and differential signal applications.

Working Principle

The PCM1864DBTR is a fully integrated high-performance data acquisition device. It consists of an analog-front-end (AFE) with an ADC, a DAC, digital control logic, and a serial digital interface (SPI or I2C). The AFE has two differential inputs with a wide input range of 6.25 V to 3.2 V. The ADC and DAC have 16-bit sampling and can operate at high-speed data rates up to 5 MSPS.

The PCM1864DBTR works by converting analog input signals into digital output signals, as well as converting digital output signals back into analog signals. Its two differential inputs allow the device to measure voltage changes across a variety of different components, including resistors and capacitors. The device is then able to measure and convert these changes into a digital signal. The digital signal is then output in either SPI or I2C format.

The PCM1864DBTR offers very high precision and accuracy in its measurements. Its 16-bit resolution and high-speed operation make it ideal for many important applications such as audio/video, medical, industrial, and automotive data acquisition. The device is also very power efficient, consuming less than 380 mW of power at 5 MSPS.

Summary

The PCM1864DBTR is a high-speed, low-power CMOS device used for data acquisition. The device consists of a highly integrated analog front end with an ADC, DAC, and digital control logic. It has two differential inputs with a wide input range, and can operate at data rates up to 5 MSPS. The PCM1864DBTR offers 16-bit resolution and high accuracy and is ideal for audio/video, medical, industrial, and automotive data acquisition applications. It is also very power efficient, consuming less than 380 mW of power at 5 MSPS.
