XD13600 – Operational Transconductance Amplifier (OTA) – Xinluda

About this part

The XD13600 from Xinluda is a dual operational transconductance amplifier (OTA) packaged in a 16-pin DIP. It integrates two independent current-controlled transconductance amplifiers, each fitted with linearizing diodes and a high-impedance output buffer. This architecture makes the XD13600 a functional equivalent of the classic LM13600 family, widely used in voltage-controlled and current-controlled analog signal processing.

Because the amplifier transconductance (gm) is set by an external bias current, the XD13600 is a versatile building block for adjustable-gain stages, voltage-controlled filters, and synthesizer-style audio circuits where smooth, parameter-controllable gain is required.

Key Features

• Two independent current-controlled (operational) transconductance amplifiers in one package
• Linearizing diodes that reduce output distortion and allow higher input signal levels
• High-impedance output buffers matched to the dynamic range of the amplifiers
• Good gm linearity and excellent matching between the two amplifiers
• High output signal-to-noise ratio
• Operating temperature range of 0°C to +70°C
• 16-pin DIP (DIP-16) through-hole package
• RoHS compliant
• Functional equivalent of the LM13600 (SOP-16 sibling: XL13600)

Applications

• Current-controlled and voltage-controlled amplifiers (VCAs)
• Voltage-controlled filters and tunable active filters
• Voltage-controlled oscillators (VCOs) and timing circuits
• Stereo and analog audio signal processing / synthesizers
• Current-controlled impedance networks
• Analog multiplexers and sample-and-hold circuits

Why Source XD13600 from Pacific Component Xchange

The XD13600 is a specialty Xinluda analog part with limited authorized-distributor coverage, which can make it difficult to procure in production quantities. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management ICs, amplifiers, and optocouplers. We help engineers and buyers secure scarce components like the XD13600 with authenticity verification, flexible quantities, and worldwide shipping.
