Integrated Circuit
Dual Operational Transconductance Amp
Description:
The NTE870 consists of two current controlled transconductance amplifiers each with differential in-
puts and a push–pull output. The two amplifiers share common supplies but otherwise operate inde-
pendently. Linearizing diodes are provided at the inputs to reduce distortion and allow higher input
levels resulting in a 10dB signal–to–noise improvement referenced to 0.5 percent THD. Controlled
impedance buffers are provided which are especially designed to complement the dynamic range of
the amplifiers.
