The NXP MC145481EN is a high-performance, single-chip Pulse Code Modulation (PCM) codec-filter that integrates the functions of both a digital-to-analog converter (DAC) and an analog-to-digital converter (ADC) into a compact package. This integrated circuit is designed to be used in telecommunication applications and is well-suited for systems that require precise audio signal conversion with minimal external components.

Key Features

• Integrated Codec and Filter: Combines both DAC and ADC functionalities for efficient signal processing.
• Low Voltage Operation: Operates from a single 5V power supply, making it suitable for low-power applications.
• Programmable Gain: Offers programmable gain settings for both the transmit and receive paths, providing flexibility in adjusting signal levels.
• High Performance: Delivers high-quality audio conversion with a signal-to-noise ratio that meets the demands of telecommunication standards.
• Power Saving Modes: Features power-down and idle modes to conserve power when the codec is not in active use.

Applications

The MC145481EN is ideal for a wide range of telecommunication applications, including:

• Wireline telephones
• Wireless handsets
• Modems
• VoIP systems
