ETEK Launches ET7460H: High-Performance Dual SPST Audio Switch with Ultra-Low 0.1Ω On-Resistance

ETEK announced the release of the ET7460H, a high-voltage, dual single-pole/single-throw (SPST) analog switch designed for premium audio applications. Engineered to deliver ultra-low distortion and exceptional signal fidelity, the ET7460H is optimized for battery-powered audio systems, portable instrumentation, and HiFi equipment.

Key Features:

Ultra-Low On-Resistance: 0.1Ω (typical) ensures minimal signal loss for pristine audio quality.

Wide Signal Range: Supports rail-to-rail negative and positive signals from -13V to +18V with ultra-low distortion.

Fast Switching: Turn-on/off times of 15µs/5µs for seamless audio routing.

Low Crosstalk: -100dB isolation at 20kHz eliminates channel interference.

Compact Design: WLCSP12 package (1.62mm x 1.23mm) saves space in portable devices.

Broad Compatibility: Operates from 2.7V to 5.5V and integrates 1.2V logic control for flexible system integration.

Applications:

HiFi audio signal switching (line-out, headset drivers).

Isolation in capless receiver and Class-D amplifier systems.

Battery-operated portable devices requiring high-voltage tolerance.

Why ET7460H?

The ET7460H solves critical design challenges in modern audio systems, such as protecting low-voltage components from high-voltage Class-D amplifier outputs while maintaining signal integrity. Its unmatched 0.016Ω channel matching and 0.001Ω on-resistance flatness ensure linear performance across the full signal range, making it ideal for audiophile-grade applications.

Availability:

The ET7460H is available in a green WLCSP12 package, rated for -40°C to +85°C operation. Samples and evaluation boards can be requested through Etek’s global distribution network.
