The ALFA RPAR AS13704 consists of four current-controlled transconductance amplifiers (OTA), each with differential inputs and a push-pull output. All amplifiers share common supplies, but operate independently. Linearizing diodes are provided at the inputs to reduce distortion and allow higher input levels. The result is a 10-dB signal-to-noise improvement referenced to 0.5 percent THD.

This device is functionally equivalent to the LM13700 (and Coolaudio V13700) except that it contains 4 OTAs in a package instead of 2, and it removes the mostly useless darlington output buffers of the 13700.
