Overview
The LA4705NA-E is a Class-AB stereo audio power amplifier manufactured by onsemi. It features a BTL (Bridge-Tied Load) dual-channel architecture designed to drive low-impedance loads, specifically supporting 2-ohm speakers. The device delivers a total output power of 25W per channel. Key electrical specifications include a minimum supply voltage of 9V and a maximum of 16V. It operates within a temperature range of -35°C to +85°C and utilizes an 18-pin SIP package for through-hole mounting.
Feature Summary
- BTL dual-channel design improves low-frequency characteristics
- Capacitor-free NF circuit reduces crosstalk phenomena
- Supports direct driving of 2-ohm speaker loads
Applications
- Car audio systems
- Home theater amplifiers
- Portable audio equipment
Procurement Notes
Verify the exact part number suffix against official onsemi documentation, as variations may exist. Confirm RoHS compliance status directly from the manufacturer's datasheet or certification documents before procurement. Ensure the supplier provides traceable origin data. Check for any specific handling requirements related to the SIP-18 package during storage and assembly processes.
Selection Notes
Select this component when a high-power, two-channel solution is required for low-impedance speaker applications. The BTL configuration allows for higher power output compared to standard bridge configurations without external coupling capacitors. Consider the thermal management capabilities of the SIP-18 package relative to the expected power dissipation in the target enclosure design.
Part Context
The LA4705NA-E belongs to onsemi's audio amplifier product line, specifically engineered for consumer and automotive audio applications. It represents a discrete power amplifier solution distinct from integrated system-on-chip designs. The component is part of a broader portfolio of audio ICs offered by onsemi, focusing on reliability and performance in standard packaging formats.
Replacement Considerations
LA4708N-E: A similar Class-AB audio amplifier from onsemi, though it features different power output and gain specifications. Verify pin compatibility and thermal requirements before substitution.
