| DARR84 Wireless Audio Processor Highly-Integrated, Multi-Application, Tri-Band and GHz Audio Processor The DARR84 is a highly-integrated wireless audio processor which extends Microchip’s KleerNet technology interoperability. The fundamental core of the DARR84 is derived from the very popular and successful DARR83 processor. The DARR84 integrates a 16-bit audio DAC plus headphone amplifier, as well as an analog audio input, including ADC and microphone amplifier to reduce overall solution costs. The DARR84 runs on two AAA batteries and headphones and headsets. Target applications include gaming, VOIP and high-end audio devices. Microchip’s DARR84 supports multiple RF bands and frequencies within each RF band and GHz and incorporates Wireless DNA technology which effectively manages common interference sources such as microwave ovens, among others. The DARR84 also has an integrated SRC, making it easy to support multiple audio sampling rates.
