Audio codecs using FLEXSOUND audio processors from Maxim

Maxim has introduced the MAX98088, a stereo audio codec that leverages Maxim's FLEXSOUND audio processor. This technology improves loudspeaker performance by optimizing the signal level and frequency response. The MAX98088 has a power consumption of 5.6mW. This device is suggested for portable multimedia and mobile phone applications.

The MAX98088 provides an evaluation (EV) kit and user interface simplify evaluation of the FLEXSOUND tools: 5-band parametric EQ, automatic level control (ALC), speaker excursion limiter, speaker power limiter, and speaker distortion (THD) limiter. These tools enable system designers to easily optimize audio performance while limiting distortion and power at the output. Microphone automatic gain control (AGC) and a noise gate optimize the signal level of microphone input signals to make the best use of the ADC dynamic range and improve voice conversion.

The integrated headphone amplifiers feature Maxim's dual-mode charge pump and Class H output stage. This architecture eliminates the need for large output capacitors and ensures click-/pop-free operation during turn-on, turn-off, and volume changes. Ground sense reduces the output noise caused by ground-return current. These amplifiers output 950mW into 8 Ohms speakers while maintaining 87% efficiency. .

Package: 3.8mm x 3.3mm, 0.4mm pitch 63-bump wafer-level package (WLP).

Operating temperature range: -40degC to +85degC

Price: Starts at US$1.98
