XL13600 – Operational Transconductance Amplifier (OTA) – Xinluda

The Xinluda XL13600 is a dual operational transconductance amplifier (OTA) with linearizing diodes and high-impedance output buffers, supplied in a 16-pin SOIC package. An LM13600-class device for current-controlled gain, filtering, and audio applications.

The Xinluda XL13600 is a dual operational transconductance amplifier (OTA) consisting of two current-controlled transconductance amplifiers, each with differential inputs and a push-pull output. Linearizing diodes are provided at the inputs to reduce distortion and allow higher input signal levels, while integrated high-impedance buffers complement the dynamic range of the amplifiers. The XL13600 is functionally a member of the classic LM13600-class OTA family, making it a practical drop-in style choice for current-controlled analog signal processing.

Because amplifier transconductance (gm) is set by an external bias current, the XL13600 is ideal for designs that need electronic gain control, voltage/current-controlled filtering, and modulation. The two on-chip amplifiers are well matched, supporting stereo and dual-channel topologies.
