SA578 - Unity gain level programmable low power compandor

Description

The SA578 is a unity gain level programmable compandor designed for low power applications.

The SA578 is internally configured as an expandor and a compressor to minimize external component count.

Features

  • Operating voltage range: 1.8V to 7V.
  • Low power consumption (1.4mA @ 3.6V).
  • 0dB level programmable.
  • Over 90dB of dynamic range.
  • Wide input/output swing capability.
  • Low external component count.
  • SA578 meets cellular radio specifications.
  • ESD hardened.
  • Power Down mode (ICC = 170µA @ 3.6V).
  • Mute function.
  • Multiple external summing capability.
  • 600Ω drive capability (10mVRMS to 1.0VRMS) 10 CO.

The SA578 is internally configured as an expandor and a compressor to minimize external component count. The summing amplifiers of the SA578 have 600Ω drive capability and the inverting input of the compressor amplifier is accessible through Pin 9 for summing multiple external signals. Power Down/Mute function is active low and requires an open collector output logic configuration at Pin 8.
