BA6125 LED level meter driver

Audio ICs LED level meter driver, 5-point, linear scale BA6125 The BA6125 is a driver IC for LED linear level meters in stereo equipment and other display applications. The IC displays the input level on five LEDs. The display level range is 35mVrms to 175mVrms in five equally-spaced 35mVrms steps. The BA6125 includes a rectifier amplifier allowing direct AC.

Features

1) Rectifier amplifier allows either AC or DC input. 2) Constant-current outputs for constant LED current when the supply voltage fluctuates. 3) Built-in reference voltage means that power supply voltage fluctuations do not effect the display. FAbsolute maximum ratings (Ta = 25_c) 4) Wide operating power supply voltage range (3.5V to 16V) for a wide range of applications. 5) Low PCB space requirements. Comes in a compact 9-pin SIP package and requires few external components. 624 Audio ICs FBlock diagram BA6125 FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 6.0V, an.
