Description
Quad OTA chip (SSOP24 SMD) – LM13700 functional replacement (without output buffers)
The 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. Linearising 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.
Features
- gm adjustable over 6 decades
