FEATURES
DESCRIPTION
The LM13700 series consists of two current

Adjustable over 6 Decades
controlled transconductance amplifiers, each with

differential inputs and a push-pull output. The two
• Excellent Matching between Amplifiers
amplifiers share common supplies but otherwise
operate independently. Linearizing diodes are
• Linearizing Diodes
provided at the inputs to reduce distortion and allow
• High Impedance Buffers
higher input levels. The result is a 10 dB signal-to-
• High Output Signal-to-Noise Ratio
noise improvement referenced to 0.5 percent THD.
High impedance buffers are provided which are
APPLICATIONS
especially designed to complement the dynamic
range of the amplifiers. The output buffers of the
• Current-Controlled Amplifiers
LM13700 differ from those of the LM13600 in that
• Current-Controlled Impedances
their input bias currents (and hence their output DC
levels) are independent of I
ABC
. This may result in
• Current-Controlled Filters
performance superior to that of the LM13600 in audio
• Current-Controlled Oscillators
applications.
• Multiplexers
• Timers
• Sample-and-Hold circuits
