Description: LED Level Meter Driver

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 n

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 fluctu
