Fonctionnalités et applications

The TS472IQT is a differential-input microphone preamplifier optimized for high-performance PDA and notebook audio systems.

This device features an adjustable gain from 0 to 40 dB with excellent power-supply and commonmode rejection ratios. In addition, the TS472 has a very low noise microphone bias generator of 2 V.

Features:

  • Low noise: 10 nV/√Hz typ. equivalent input noise at F = 1 kHz
  • Fully-differential input/output
  • 2.2 to 5.5 V single supply operation
  • Low power consumption at 20 dB: 1.8 mA
  • Fast start up time at 0 dB: 5 ms typ.
  • Low distortion: 0.1% typ.
  • 40 kHz bandwidth regardless of the gain
  • Active low standby mode function (1 μA max)
  • Low noise 2.0 V microphone bias output
  • Available in flip-chip lead-free package and in QFN24 4 x 4 mm package
  • ESD protection (2 kV)

Applications:

  • Video and photo cameras with sound input
  • Sound acquisition and voice recognition
  • Video conference systems
  • Notebook computers and PDAs
