DESCRIPTION

The A4712 is a Dual Wide-Bandwidth, fast single-pole double-throw (SPDT) CMOS switch featuring an On-Resistance of 0.4 ohm at VDD=2.7V and wide power supply range from 1.65V to 5.5V.

The A4712 can be used as an analog switch or as a low-delay bus switch.

Break-before-make function for both parts eliminates signal disruption during switching from preventing both switches being enabled simultaneously.

FEATURES

 Wide Power Supply Range:1.65V to 5.5V

 Low On-Resistance:

RON(NC) = 0.4Ω(VCC=2.7V)

RON(NO) = 0.5Ω(VCC=2.7V)

 Low On-Resistance Flatness:

RONF(NC) = 0.15Ω max (VCC=2.7V)

RONF(NO) = 0.25Ω max (VCC=2.7V)

 Rail-to-Rail Signal Range

 High Off-Isolation: -60dB (f=100 kHz)

 Crosstalk Rejection: -67dB

 Low Total Harmonic Distortion: 0.05
