XD13700 – Operational Transconductance Amplifier (OTA) – Xinluda

The Xinluda XD13700 is a dual operational transconductance amplifier (OTA) with built-in linearizing diodes and output buffers in a DIP-16 package, functionally equivalent to the classic LM13700.

The Xinluda XD13700 is a dual operational transconductance amplifier (OTA) featuring on-chip linearizing diodes and high-impedance output buffers, supplied in a through-hole DIP-16 package. The device integrates two independent transconductance amplifiers that share common supply rails, with transconductance (gm) that is adjustable over six decades by an external amplifier bias current. This makes the XD13700 a versatile building block for voltage-controlled amplifiers, filters, oscillators, and other analog signal-processing functions. It is a form-, fit-, and function-compatible alternative to the widely used LM13700-class OTA.
