Maxim Integrated MAX9860ETG+T Audio Codec

The MAX9860ETG+T from Maxim Integrated is a high-performance, low-power, mono audio codec designed to provide a comprehensive audio solution for portable devices. This integrated circuit simplifies the design of audio systems by combining an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), a digital audio interface, and a headphone amplifier in a single, compact component.

With its 24-bit audio processing capabilities, the MAX9860ETG+T delivers pristine sound quality suitable for a wide range of applications, from mobile phones and tablets to wireless headsets and digital cameras. The device supports sample rates from 8kHz to 48kHz, ensuring compatibility with standard audio formats while providing flexibility for various use cases.

The codec's integrated programmable gain amplifier (PGA) on the ADC path allows for fine-tuning of the input signal, ensuring optimal recording levels. The DAC path features a high-output headphone amplifier that can drive 16Ω to 100Ω loads, making it versatile for different headphone types. Additionally, the headphone amplifier offers a low 0.01% total harmonic distortion plus noise (THD+N), ensuring a clear audio output.

Designed with power efficiency in mind, the MAX9860ETG+T operates on a single 1.8V power supply, which is ideal for battery-powered devices. It also includes flexible power management options, allowing designers to minimize power consumption when the audio features are not in use.

The digital audio interface of the MAX9860ETG+T supports I²S, left-justified, and PCM data formats, providing easy integration with most microcontrollers and digital signal processors. The small 24-pin TQFN package (4mm x 4mm) with exposed pad makes it suitable for space-constrained applications.

Maxim Integrated ensures reliability and performance by offering the MAX9860ETG+T with an extended temperature range of -40°C to +85°C, accommodating harsh operating environments. Whether for personal entertainment, communication devices, or digital media, the MAX9860ETG+T stands out as a versatile and reliable audio codec solution for designers looking to enhance their audio system capabilities.
