XL13 Series – Dual Operational Transconductance Amplifier (OTA) – Xinluda

The Xinluda XL13 series (XL13600 / XL13700) is a family of dual operational transconductance amplifiers (OTAs) with linearizing diodes and high-impedance output buffers, supplied in SOP-16. Available for RFQ from Pacific Component Xchange.

The Xinluda XL13 series is a family of dual operational transconductance amplifiers (OTAs) comprising the XL13600 and XL13700. Each device integrates two current-controlled transconductance amplifiers, each featuring differential inputs and a push-pull output. Linearizing diodes are provided at the inputs to reduce output distortion and allow higher input signal levels, delivering a 10 dB signal-to-noise improvement referenced to 0.5 percent THD. The XL13 series is functionally aligned with the industry-standard LM13600/LM13700 OTAs, making it a practical drop-in alternative for audio and signal-processing designs.

The XL prefix denotes the SOP-16 surface-mount package; the equivalent through-hole DIP-16 part is offered by Xinluda under the XD13600 / XD13700 designation. The XL13700 differs from the XL13600 in that its output-buffer input bias currents (and therefore their output DC levels) are independent of the amplifier bias current (IABC), which can yield superior performance in audio applications.

Why Source XL13 from Pacific Component Xchange

The Xinluda XL13 series has little to no authorized-distributor stock through mainstream channels, which makes it a challenge for designers maintaining audio synthesizers, analog signal-processing boards, and legacy OTA-based circuits. Pacific Component Xchange specializes in hard-to-find and obsolete power-management and analog ICs, and can help you locate, verify, and procure the XL13600 and XL13700 in SOP-16 and the DIP-16 XD equivalents. Every part is sourced with a focus on authenticity and supply-chain integrity, and we ship globally.
