The SGM3157 is a single, bidirectional, single-pole/double- throw (SPDT) CMOS analog switches designed to operate from a single +1.8V to +5.5V supply. It features high-bandwidth (300MHz) and low ON-resistance (4.5Ω typ), Targeted applications for audio switching.

SGM3157 features guaranteed on-resistance matching (0.3Ω max) between switches and guaranteed on-resistance flatness over the signal range (2.3Ω TYP). This ensures excellent linearity and low distortion when switching audio signals.

SGM3157 is available in a SC70-6 package.
