BCT4717
4.0Ω, 300MHz Bandwidth, Dual SPDT Analog Switch
GENERAL DESCRIPTION
The BCT4717 is a dual, 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 (4.0Ω typ), Targeted applications for audio switching.
BCT4717 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.
The BCT4717 is a committed dual single-pole/double -throw (SPDT) that consist of two normally open (NO) and two normally close (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer.
BCT4717 is available in WQFN-10 package.
