Features

* 1) Rectifier amplifier allows either AC or DC input. 2) Wide display level range (
* 13 to +17), so signals with large dynamic range can be displayed. 3) Constant-current outputs for constant LED current when the power supply voltage fluctuates. 4) Built-in reference voltage means that power supp

Applications

* The IC displays the input level (range:
* 13dB to +17dB) on a 5-point, bar-type LED display. The BA6144 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
