MAX4910ETE+

Analog Switches - Special Purpose Overview

The MAX4910ETE+ is a quad single-pole double-throw (SPDT) analog switch designed for clickless audio applications. It operates from a single +1.8V to +5.5V supply and features negative signal handling, passing signals as low as VCC - 5.5V without distortion. The device includes internal shunt resistors on all normally open and normally closed terminals to automatically discharge capacitance and reduce audible switching artifacts. It utilizes two digital control inputs, CB1 and CB2, where each bit manages a pair of switches. Key electrical parameters include a typical on-resistance of 0.37Ω for channels 1 and 3, a maximum supply current of 2µA at +5.5V, and an operating temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Negative signal capability allows undistorted passage of signals below ground potential down to VCC - 5.5V.
• Internal shunt resistors on all NO and NC terminals automatically discharge precharged nodes to suppress click-and-pop sounds.
• Break-before-make switching logic prevents momentary connection between old and new signal paths during transitions.
• High power-supply rejection ratio minimizes the impact of supply noise on the analog signal path.

Analog Switches - Special Purpose Applications

• Cell phones
• PDAs and handheld devices
• Notebook computers
• MP3 players

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity by checking the top marking against the datasheet specifications. Confirm the package code matches T1633-4 for the 16-pin TQFN-EP configuration. Ensure the ordering suffix indicates lead-free construction. Cross-reference the manufacturer part number with official Analog Devices documentation to validate revision status before integration into production designs.

Analog Switches - Special Purpose Selection Notes

Select this component when designing audio routing circuits that require low distortion and minimal switching noise. The dual-control-bit architecture suits systems needing independent pairing of four switches. Verify that the required signal voltage swing remains within the specified VCC - 5.5V lower limit. Consider the exposed pad thermal requirements for proper heat dissipation in dense PCB layouts.

Analog Switches - Special Purpose Part Context

This component belongs to the MAX4910/MAX4911/MAX4912 family of quad SPDT audio switches. While sharing similar core functionality, the MAX4910ETE+ specifically uses two control bits for paired switching. Other variants in the series offer different control schemes, such as the single-bit enable feature found in the MAX4911 or reduced shunt resistor configurations in the MAX4912.
