AS1702V-T

Overview

The AS1702V-T is a single-channel differential audio power amplifier designed for portable devices. It delivers 1.8W continuous average power to a 4Ω load with less than 1% THD+N, operating from a single 2.7V to 5.5V supply. The device features adjustable gain via external components and includes integrated click-and-pop suppression. It operates within a temperature range of -40°C to +85°C and utilizes a 10-pin DFN package.

Feature Summary

Adjustable gain configuration using external feedback resistors
Bridge-tied load (BTL) design minimizing external component count
Integrated shutdown circuitry reducing quiescent current below 100nA
Click-and-pop suppression circuitry for quiet power-up and shutdown

Applications

MP3 and CD players
Mobile phones
Portable DVD players
Hand-held battery-powered devices

Procurement Notes

Verify the specific ordering code matches the required package type and gain configuration. Confirm that the application environment remains within the specified electrical limits and thermal constraints. Ensure proper layout practices are followed to optimize performance and reliability.

Selection Notes

Select this component when an adjustable gain setting is required for the audio front-end. It is suitable for designs needing high output power in a small footprint. Consider the BTL topology for efficient power delivery without large DC-blocking capacitors.

Part Context

This part belongs to the AS1702-AS1705 family of 1.8W single-channel audio amplifiers. While other variants offer fixed gains, the AS1702V-T specifically provides adjustable gain capabilities. It shares pin compatibility with similar industry amplifiers but offers distinct internal circuitry optimized for low-voltage operation.

Replacement Considerations

Pin-compatible substitutes include the LM4895 and MAX9718A/B/C/D series. Verify functional equivalence regarding gain adjustability and package dimensions before substitution.
