Overview
The LM13700MX/NOPB, produced by Texas Instruments, is a dual operational transconductance amplifier. This device features two current-controlled transconductance amplifiers, each with differential inputs and a push-pull output. The amplifiers share common supplies but operate independently, making them versatile for various applications. The inclusion of linearizing diodes at the inputs reduces output distortion and allows for higher input levels, resulting in a 10-dB signal-to-noise improvement referenced to 0.5 percent THD. High impedance buffers are also provided to enhance the dynamic range of the amplifiers.
