BA6125 - LED level meter driver

Key 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.

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 input, and has constant-current outputs, so it can directly drive the LEDs without variations in LED current due to supply voltage fluctuations. FApplications Battery checkers, signal meters, and other display devices. FFeatures 1) Rectifier amplifier allows either AC or DC input. 2) Constant-current outputs for constant LED current when the supply voltage fluctuates.
