A4712
DUAL SPDT ANALOG SWITCH
0.4Ω NC AND 0.5Ω NO, LOW-VOLTAGE, SINGLE-SUPPLY
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%
Available in CSP10 Package
The A4712 is available in CSP10 Package.
