GS3157
Ultra-low resistance SPDT analog switch with 1.5Ω on-resistance for high-fidelity signal routing.
Product Overview
Description
The GS3157 is an ultra-low resistance SPDT analog switch with 1.5Ω typical on-resistance for applications requiring minimal signal degradation.
The lower resistance reduces signal attenuation and distortion, making it ideal for high-fidelity audio and precision measurement applications. Same wide supply range as GS4157.
Features include excellent linearity (THD -90dB), low charge injection, and high off-isolation.

Frequently Asked Questions
When should I choose GS3157 over GS4157?
Choose GS3157 when signal quality is critical - high-fidelity audio, precision measurements, or low-voltage signals. The lower resistance and better linearity justify the higher cost. Use GS4157 for standard switching where 2.5Ω is acceptable.
GS3157 for critical signals, GS4157 for standard apps.
