Product details

LM13700N

The 13700 is a dual operational transconductance amplifier with linearising diodes and buffers. It consists of two current controlled transconductance amplifiers, each with different inputs and a push pull output. The two amplifiers share common supplies, but otherwise operate independently. Linearising diodes are provided at the inputs to reduce distortion and allow higher input levels. The result is a 10dB signal-to-noise improvement referenced to 0.5% THD. High impedance buffers are provided which are specially designed to complement the dynamic range of the amplifiers.The IC has many useful applications such as voltage controlled amplifiers, voltage controlled resistors, voltage controlled filters, voltage controlled oscillators, phase locked loop, Schmitt trigger tachometer (f to v), peak detector and hold, sample and hold, ramp and hold, true RMS convertor, variable temperature coefficient voltage reference, pulse width modulator, log current source, multiplexer, zero standby power timer, four quadrant multiplier, amplitude monitor and stereo volume control. A data sheet is available which shows circuit details of all the above applications.
