SGM3719中文资料4Ω, 400MHz Bandwidth, SPDT Negative Signal Handling Analog Switch数据手册SGMICRO规格书

描述 Description

The SGM3719 is a bidirectional, single-pole/double-throw (SPDT) CMOS analog switch designed to operate from a single 2.5V to 5V supply. It features high bandwidth (400MHz) and low on-resistance (4Ω TYP), and the switches can handle negative signal down to -2V.

The SGM3719 features a guaranteed on-resistance matching of 0.1Ω (TYP) between switches and a guaranteed on-resistance flatness of 1Ω (TYP) over the signal range. This ensures excellent linearity and low distortion when switching audio signals.

The SGM3719 is a committed single-pole/double-throw (SPDT) switch that consists of one normally open (NO) and one normally closed (NC) switches. This configuration can be used as a 2-to-1 multiplexer.

The SGM3719 is available in a Green SOT-23-6 package.
