AS1705V-T

Overview

The AS1705V-T is an audio amplifier IC from the AS1702/3/4/5 series manufactured by ams-OSRAM USA INC. It is designed for use with the AS1702/3/4/5 Demoboard, which supports differential signal inputs and provides configurable gain and output impedance settings. The device operates within a supply voltage range of 2.7 to 5.5V and features adjustable shutdown modes. The demoboard allows for measurement points at OUT+, OUT-, and BIAS-GND, facilitating evaluation in applications requiring precise audio signal amplification.

Feature Summary

• Supports differential signal input for enhanced noise rejection
• Configurable amplifier gain and output impedance via jumpers
• Includes dedicated shutdown mode control for power management
• Provides accessible measurement points for OUT+ and OUT- signals

Applications

• Audio signal amplification evaluation
• Differential input circuit testing
• Low-voltage audio system prototyping

Procurement Notes

Verify the specific package type and tape-and-reel configuration against official distributor listings. Confirm that the component matches the AS1705 variant intended for the demoboard application. Ensure compliance with RoHS directives as indicated in standard manufacturer documentation. Cross-reference part numbers with austriamicrosystems archives for accurate identification.

Selection Notes

Select this component when evaluating audio amplifier performance using the AS1702/3/4/5 demoboard. Consider its compatibility with 2.7V to 5.5V supply rails and differential input requirements. Evaluate jumper configurations for gain and output impedance matching your load conditions. Verify availability through authorized channels given potential discontinuation status in some regions.

Part Context

The AS1705V-T belongs to the AS1702/3/4/5 family of audio amplifiers developed by austriamicrosystems (now ams-OSRAM). These devices are commonly used in portable electronics and automotive audio systems where low voltage operation and high fidelity are required. The demoboard serves as a reference design platform for developers to test and optimize circuit parameters before integration into final products.

Replacement Considerations

Direct substitutes include other members of the AS1702/3/4/5 series such as AS1702, AS1703, or AS1704, provided pinout and functional compatibility with the demoboard are confirmed. Check datasheets for equivalent gain stages and supply voltage ranges.
