AiT Semiconductor Inc. www.ait-ic.com A4712 DUAL SPDT ANALOG SWITCH 0.4Ω NC AND 0.5 Ω NO, LOW -VOL TAGE, SINGLE-SUPPL Y REV1.2 - JAN 2009 RELEASED, AUG 2014 UPDATED - - 1 - DESCRIPTION FEATURES The A4712 is a Dual Wide -Bandwidth, fast single-pole double-throw (SPDT) CMOS switch featuring an On-Resistance of 0.4 ohm at V DD=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. The A4712 is available in CSP10 Package. 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 ORDERING INFORMATION APPLICATION Package Type Part Number CSP10 G10 A4712G10R A4712G10VR Note V: Halogen free Package R: Tape & Reel AiT provides all RoHS products Suffix “ V “ means Halogen free Package Wireless Handsets MP3 Players Portable Electronic Devices Relay Replacement PDAs Audio & Video Signal Routing PCMCIA Cards Computer Peripherals Modems
