U2861B-MFPY 71

Overview

The Microchip Technology U2861B-MFPY 71 is a single-channel FM demodulator integrated circuit designed for consumer audio applications. It operates within a supply voltage range of 4.5V to 6V and utilizes an analog interface. The device is housed in a 14-SOIC surface-mount package with a width of 3.90mm. This component functions specifically as an FM demodulator, converting frequency-modulated signals into audio outputs suitable for standard consumer electronics.

Feature Summary

• Single-channel FM demodulation function
• Analog interface for signal processing
• Operates on 4.5V to 6V supply voltage
• 14-SOIC surface-mount package

Applications

• Consumer audio equipment
• FM radio receivers
• Audio signal processing circuits

Procurement Notes

Verify the specific ordering suffix MFPY 71 against manufacturer documentation to confirm tube packaging and exact electrical tolerances. Ensure compatibility with the required 4.5V-6V power supply rails during system design integration.

Selection Notes

Select this component when a dedicated single-channel FM demodulator is required for low-voltage consumer audio systems. Confirm that the 14-SOIC footprint fits the PCB layout constraints and that the analog interface meets the source impedance requirements of the preceding RF stage.

Part Context

This part belongs to the Audio Special Purpose category within Microchip's portfolio. It serves as a specialized solution for FM signal extraction in compact audio devices, distinct from general-purpose operational amplifiers or multi-channel codecs.

Replacement Considerations

No public substitute part numbers are documented for this specific model. Verify pinout and electrical specifications if considering alternative FM demodulators from other manufacturers.
