DARR84 Wireless Audio Processor Highly-Integrated, Multi-Application, Tri-Band (2.4, 5.2 and 5.8 GHz) Audio Processor Summary 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 (2.4, 5.2 and 5.8 GHz) and incorporates Wireless DNA technology which effectively manages common interference sources such as Wi-Fi®, Bluetooth® and microwave ovens, among others. The DARR84 also has an integrated SRC, making it easy to support multiple audio sampling rates.
