XD386-1 – Audio Power Amplifier – Xinluda

The Xinluda XD386-1 is a low-voltage audio power amplifier in a DIP-8 package, part of Xinluda’s 386 family (XL386 SOP-8 / XD386-1 DIP-8 / XL386-MS MSOP-8) with the classic 386/LM386-compatible pinout. Available now for RFQ from Pacific Component Xchange.

The Xinluda XD386-1 is a low-voltage, low-power audio power amplifier supplied in an 8-pin DIP (PDIP-8) package. It is the through-hole DIP-8 member of Xinluda’s “386” amplifier family, which the manufacturer’s datasheet documents together as XL386 (SOP-8), XD386-1 (DIP-8), and XL386-MS (MSOP-8). The device uses the same pin configuration as the industry-standard 386/LM386 amplifier, so it can be used in classic 386-based, battery-powered consumer audio circuits with minimal external part count.

The amplifier has an internally fixed voltage gain of 20, which can be increased up to 200 by adding a single resistor and capacitor between the gain pins (pins 1 and 8). Its inputs are ground-referenced and the output automatically self-centers to one-half the supply voltage, simplifying single-supply audio circuit design.

Key Features

• Low-voltage audio power amplifier (386-family architecture)
• Same pin configuration as the classic 386/LM386 amplifier
• Supply voltage range: 4 V to 12 V (XD386-1)
• Internally fixed voltage gain of 20, adjustable up to 200 with external R/C (26 dB typ., 46 dB with 10 uF from pin 1 to 8)
• Low quiescent current drain: 4 mA typ. (8 mA max) at V_S = 6 V
• Low total harmonic distortion: 0.2% (A_V = 20, V_S = 6 V, R_L = 8 Ω, P_O = 125 mW, f = 1 kHz)
• Output power: 325 mW typ. (V_S = 6 V, R_L = 8 Ω, THD = 10%)
• Ground-referenced input
• Self-centering output quiescent voltage (biases to V_S/2)
• Minimum external parts count
• 8-pin DIP (PDIP-8) through-hole package

Note: electrical parameters above are taken from the Xinluda XL386/XD386-1 datasheet. Confirm final test limits against the manufacturer’s current device documentation for your application.

Applications

• AM-FM radio amplifiers
• Portable tape/media player amplifiers
• Intercoms and TV sound systems
• Line drivers and small servo drivers
• Ultrasonic drivers
• Battery-operated hobby and DIY audio projects

Why Source XD386-1 from Pacific Component Xchange
