Datasheets

This 2N6790 device is military qualified per MIL-PRF-19500/555 up to a JANTXV level for high-reliability applications. A commercial grade RoHS compliant version is also available with the "e3" suffix.  Microsemi also offers numerous other products to meet higher and lower power voltage regulation applications.

Electret Condenser Microphone (ECM) Pre-Amplifier
The AAP572X ECM Pre Amplifiers were designed for the recent exclusive use of Plantronics, Inc. of Santa Cruz, CA for high end audio headset microphone applications. The AAP572X is now available for general sale to the audio microphone marketplace. The performance of this Pre-Amplifier is such that it enables design of enhanced end system products, due to its various gain options, ultra-low noise and other high performance features.

The AAP572X ECM Pre-Amplifier provides a number of performance advantages over prior ECM Pre-Amplifier products. Key features
include ultra low input capacitance (1pF typical) and quiescent current (270?A typical), with ultra low equivalent input noise (2 to 2.65 ?VRMS, A-Weighted, with the microphone capacitor short circuited, gain version dependent). Additionally, the Pre-Amplifier sports a high pass filter with operation down to 1.45V. Other key features include THD performance below 1% maximum, output impedance of 25? typical, with exceptionally high tolerance to RF interference and ESD tolerance (8kV).

The AAP572X is offered with three gain options, 14dB, 19dB and 26dB. Packaging is bumped chip scale SMD configuration, with a size of 1.09mm x 1.12mm and an overall thickness of 350?m (including solder bumps). Optimum for 3mm microphones, the die is RoHS compliant, with lead free solder pads of 118?m diameter. Packing styles available are 2” x 2” Waffle Pack with 400 units per pack, or Tape and Reel with 3500 units/reel.
