AZ386P-E1

Overview

The AZ386P-E1 is a low voltage audio power amplifier manufactured by Diodes Incorporated, available in a DIP-8 package. It operates within a supply voltage range of 4V to 16V and features an internally set gain of 20, adjustable up to 200 via external components. The device draws a quiescent current of 6mA at 6V and delivers output power ranging from 250mW to 1000mW depending on the load and supply conditions. Designed for battery operation, it includes ground-referenced inputs and automatic half-supply voltage biasing.

Feature Summary

• Internally set voltage gain of 20 with expandability to 200 using external resistors and capacitors
• Low quiescent current drain suitable for battery-powered applications
• Ground-referenced inputs with automatic half-supply voltage output biasing
• Minimum external component count required for basic operation

Applications

• AM-FM Radio Amplifier
• Cordless Phone
• TV Sound Systems
• Portable Tape Player Amplifier
• Intercoms

Procurement Notes

Verify the specific suffix P-E1 confirms the DIP-8 tube packaging and RoHS compliance status before ordering. Confirm that the intended application does not require AEC-Q100 automotive qualification, as this standard part is not designated for such use. Check for active discontinuation notices or recommended new design alternatives provided by the manufacturer prior to final procurement decisions.

Selection Notes

Select this component when a low-voltage, single-channel mono audio amplifier is required with minimal external parts. Ensure the operating temperature range of 0°C to +70°C aligns with the system environment. Verify that the input signal levels are compatible with the ground-referenced input structure and that the desired gain setting can be achieved within the specified 20 to 200 range using available passive components.

Part Context

The AZ386 series includes variants in both SOIC-8 (AZ386M) and DIP-8 (AZ386P) packages. The AZ386P-E1 specifically denotes the DIP-8 through-hole version with RoHS compliance. This family is categorized under Audio ICs and is designed for consumer electronics where low power consumption and simple integration are prioritized over high-fidelity performance metrics.

Replacement Considerations

The datasheet explicitly states 'NOT RECOMMENDED FOR NEW DESIGN' and suggests using the PAM8304 as an alternative. Engineers should evaluate the PAM8304 for new projects, though existing designs may continue to utilize the AZ386P-E1 if supply availability permits.
