BA6137 - LED Level Meter Driver

Datasheet Summary

Features

  • 1) Rectifier amplifier allows either AC or DC input. 2) Constant-current outputs for constant LED current when the power supply voltage fluctuates. 3) Current output is optimized for red LEDs, for low power dissipation. 4) Built-in reference voltage means that power supply voltage fluctuations do not effect the display. 5) Wide operating power supply voltage range (3.5V to 16V) for a wide range of.

Audio ICs LED level meter driver, 5-point, VU scale BA6137 The BA6137 is a driver IC for LED VU level meters in stereo equipment and other display applications. The IC displays the input level (range: *10dB to +6dB) on a 5-point, bar-type LED display. The BA6137 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 power supply voltage fluctuations. FApplications VU meters, 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 power supply voltage fluctuates. 3) Current output is optimized for red LEDs, for low power dissipation.
