Texas Instruments LM13700N Dual Transconductance Op Amp
Order Code:
Brand:
Texas Instruments
MPN: LM13700N 82-5038
- RoHS Compliant
- Country of Origin: Philippines
Discontinued
LM13700 consists of two current controlled transconductance amplifiers, each with differential 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. High impedance buffers complement the dynamic range of the amplifier.
- Through-hole DIL-16 package
- Forward transconductance adjustable over 6 decades
- Excellent gm linearity
- Excellent matching between amplifiers
- High output signal-to-noise ratio
- Applications include current-controlled amplifiers, current-controlled oscillators, multiplexers, timers, sample-and-hold circuits

Reviews
A design classic
Reviewed by: Christopher Hunter - Friday, April 6, 2018This dual Operational Transconductance Amplifier chip is a true design classic. I've made use of them in designs for years. Unfortunately, they tend to add some distortion to audio passing through them, and they're noisier than modern op-amps, but with smart design, these limitations can be overcome. The channel matching is excellent, and if used as a variable gain element in the negative feedback loop of a high quality op-amp, most of the limitations are overcome. In the feedback loop of an NE5532, I get <0.01% THD and around -110dB noise - perfectly acceptable in a music production environment.
