Overview
The AS1705-T is a mono audio amplifier integrated circuit manufactured by ams-OSRAM USA INC. It is housed in a 10-DFN package and delivers an output power of 1.8W. The device operates within a supply voltage range of 2.7V to 5.5V. It supports differential signal inputs and includes configurable gain settings, specifically Av = 4 for the AS1705 variant. The component is designed for use with various load impedances, including 4 Ohm and 8 Ohm configurations.
Feature Summary
- Provides mono audio amplification functionality
- Supports differential input signal processing
- Includes configurable shutdown mode control
Applications
- Audio system evaluation using dedicated demoboard setups
- Testing with differential sinusoidal signal sources
- Driving headphones or speakers with specified impedance loads
Procurement Notes
Verify that the specific part number corresponds to the AS1705 variant rather than the AS1702, AS1703, or AS1704, as jumper configurations differ significantly between these models. Confirm the manufacturer origin from austriamicrosystems (now ams OSRAM) and ensure compatibility with the required 2.7V to 5.5V operating voltage range for your application design.
Selection Notes
Select this component when a single-channel audio amplifier is required for low-voltage applications. Ensure the design accommodates the 10-DFN package footprint. Verify that the target load impedance matches the available output impedance settings on the evaluation hardware. Consider the specific gain requirements, as the AS1705 utilizes a fixed internal gain configuration distinct from other variants in the series.
Part Context
The AS1705 belongs to the AS1702/03/04/05 family of audio amplifiers produced by austriamicrosystems. This family shares similar packaging and operational principles but differs in internal gain structures and input resistor configurations. The AS1705 specifically targets applications requiring a gain setting of Av = 4, distinguishing it from the AS1702 which offers selectable external gain options.
Replacement Considerations
Substitute parts must be verified against the official datasheet for the AS1702/03/04/05 family. No public confirmed substitute part numbers are identified in the provided documentation.
