Integrated Circuit
5 LED VU Level Meter
Description:
The NTE1561 is a monolithic integrated circuit in a 9–Lead SIP type package designed for use as a
5 dot LED level meter driver. With a built–in rectifying amplifier, this device is suitable for AC/DC level
meter applications such as VU meters or signal meters.
Features:
D Built–In High Gain Rectifying Amplifier (Av = 26dB)
D Low Radiation Noise when LED Turns On
D Logarithmic Indicator for Bar Type 5 Dot LED (–10, –5, 0, +3, +6dB)
D Constant Current Output: IO = 15mA Typ
D Wide Operating Supply Voltage Range: 3.5V to 16V
D Minimum Number of External Components Required
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
