BA681A General Description
The BA681A is a monolithic IC for LED power meter applications. The display level range is 6mVrms to 359mVrms (Typ.) divided into 12 points with repeated interval spacings of 3dB, 3dB and 4dB. The 0dB level is 180mVrms (Typ.) and the range is -30dB to +16dB. The constant current outputs can be set using external components allowing use of different color LEDs in various combinations.
BA681A Features
· 12-point power meter driver for bar / dot displays.
· Fixed-current outputs that can directly drive LEDs.
· Output current can be set using external resistors allowing different types of LEDs to be used in combination.
· Built-in half-wave rectifier amplifier.
·LED on and off timing can be set using an external capacitor and resistor.
· With bar-type display, by connecting four LEDs in series, power dissipation is reduced.
· Each group of three LEDs is a 10dB step which is ideal for power meter applications.
· Fixed-current outputs that can directly drive LEDs.
· Output current can be set using external resistors allowing different types of LEDs to be used in combination.
