LM13700MX

The LM13700MX is an integrated circuit that includes two operational transconductance amplifiers (OTAs) with linearizing diodes and buffers. It is commonly used in analog signal processing applications such as audio synthesis, voltage-controlled oscillators (VCOs), and filters. The LM13700MX offers improved performance over traditional OTAs by incorporating linearizing diodes that reduce distortion and enhance linearity.
Each OTA within the LM13700MX provides a current output that is linearly proportional to the input voltage, controlled by an external bias current. This makes it highly versatile for tasks requiring gain control and signal modulation. The IC also includes a pair of Darlington buffer transistors to further enhance the interface with low-impedance loads.
The LM13700MX is valued for its wide bandwidth, large dynamic range, and low distortion. Its compact design and dual-channel configuration make it suitable for applications requiring multiple signal processing paths. Typically housed in a small outline IC package, it is well-suited for compact or high-density circuit designs.
