FSA2276UMX

Analog Switches - Special Purpose Overview

The FSA2276UMX is a single-channel analog switch IC configured as a double-pole double-throw (DPDT) device, manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance of 1 Ohm. The component supports a -3 dB bandwidth of 380 MHz and handles a DC switch current of 100 mA. Key timing parameters include a maximum turn-on time of 100 ms and a maximum turn-off time of 20 us. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a compact 12-UMLP package measuring 1.8x1.8 mm.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and check for any recent product change notices regarding material declarations or packaging updates before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing low-voltage audio paths requiring DPDT switching capability. The 1.65 V minimum supply voltage makes it suitable for battery-powered systems. Verify that the 1 Ohm on-resistance meets the signal integrity requirements of the specific audio application.

Analog Switches - Special Purpose Part Context

This part belongs to the FSA2276 series of analog switches designed specifically for audio applications. It is distinct from general-purpose digital switches due to its optimized characteristics for handling audio frequency signals and negative voltage swings.

Analog Switches - Special Purpose Replacement Considerations

Public documentation indicates DIO32276 as a potential alternative. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
