■ DESCRIPTION
The UTC LA2284/A is a monolithic integrated circuit designed for 5-dot LED level meter drivers with a built-in rectifying amplifier. It is suitable for AC/DC level meters such as VU meters or signal meters.

■ FEATURES
* High gain rectifying amplifier included (Gv=26dB)
* Low radiation noise when LED turns on
* Logarithmic indicator for 5-dot LED of bar type
* Constant current output(15mA)
* Wide operating supply voltage
* Not necessary diode or transistor for ALC
* Minimum number of external parts required
