Data Acquisition - ADCs/DACs - Special Purpose

The PCM1863DBT is an advanced analog-to-digital converter with differential inputs and an integrated audio amplifier specifically designed for automotive applications. The device combines a 16-bit delta-sigma-ADC and a low power audio amplifier in one device. It features a differential input range of ±10V and a signal-to-noise ratio of better than 94dB.

Application Field

The PCM1863DBT is designed for use in automotive audio systems in order to convert analog audio signals into digital data. This device is ideal for use in audio applications such as car radios, CD players and other entertainment systems. It is also suitable for use in industrial applications where it can be used to convert analog signals into digital data for further processing.

Working Principle

The PCM1863DBT is based on a 16-bit delta-sigma-ADC architecture. This architecture is implemented by connecting a series of capacitors to form an integrating filter. As the capacitor charges and the filter tracks the input signal, it causes variations in the output voltage. This is then digitized by a 16-bit delta-sigma ADC and the resulting digital data is sent to the audio amplifier for processing.

The PCM1863DBT also features a low power audio amplifier, which is designed to provide a higher signal-to-noise ratio than a traditional amplifier. The amplifier is composed of current feedback amplifiers arranged in a bridge configuration. This configuration allows the amplifier to produce a balanced output signal with a maximum output voltage of 4V RMS.

The PCM1863DBT is a versatile device that can be used in a variety of different applications. It is capable of providing high-resolution audio and data conversion in a wide range of audio applications. It can also be used in industrial applications, where it can be used to convert analog signals into digital data for further processing. This device is ideal for use in audio applications such as car radios, CD players and other entertainment systems.
