LA4587M - Preamplifier + Power Amplifier

Description

VREF amplifier is referenced to this decoupling capacitor.

The VREF SVRR depends on the value of this capacitor.

Note that if the capacitance is reduced, the SVRR worsens.

Features

  • CC preamplifier and power amplifier inputs; anti-buzz provision. Specifications Maximum Ratings at Ta = 25 °C Parameter Maximum supply voltage Allowable power dissipation Operating temperature Storage temperature Symbol VCC max Pd max Topr Tstg Allowable power dissipation, Pd max.
  • mW . Preamplifier has a high open-loop gain (VG = 73 dB). . Preamplifier requires no NF capacitor. . Virtual ground capacitor can be 1 µF or less. (Lower amplifier built in. ) is achieved by having a V . i.
