UM2268/UM2268A 0.4Ω Ultra Low ON-Resistance, Dual, SPDT Analog Switch UM2268 QFN10 1.8×1.4 UM2268A QFN10 2.1×1.6 General Description The UM2268/UM2268A is a dual, low-power single-pole/ double-throw (SPDT) analog switch that operates from a single +1.8V to +4.4V supply. The UM2268/UM2268A features guaranteed on-resistance matching (0.04Ω TYP) between switches and guaranteed on resistance flatness over the signal range (0.08Ω TYP), as well as high off-isolation and low crosstalk. This ensures excellent linearity and low distortion when switching audio signals. The UM2268 is available in Pb-free QFN10 package (1.8mm×1.4mm×0.55mm), while the UM2268A is available in Pb-free QFN10 package (2.1mm×1.6mm×0.55mm). Applications Features Portable Instrumentation Battery-Operated Equipment Computer Peripherals Speaker and Earphone Switching Medical Equipment Audio and Video Switching Pin Configurations VCC Operating Range: +1.8V to +4.4V Low On-Resistance: 0.4Ω(TYP) at +4.4V On-Resistance Matching: (0.04Ω TYP) On-Resistance Flatness: (0.08Ω TYP) -3dB Bandwidth:80MHz Low Off-Isolation: -78dB (100kHz) Low Crosstalk: -93dB (100kHz) TTL/CMOS Compatible Break-Before-Make Switching Rail-to-Rail Input and Output Operation Lead (Pb) Free QFN10 Package Top View NC2 NO1 2 1 NO2 3 10 NC1 GND 4 9 V+ COM2 5 8 COM1 6 7 IN2 IN1 M: Month Code UM2268 QFN10 1.8×1.4 ________________________________________________________________________ http://www.union-ic.com Rev.07 Feb.2014 1/11 UM2268/UM2268A AL GND M NO2 NC2 NO1 NC1 VCC COM2 IN2 M: Month Code UM2268A QFN10 2.1×1.6 IN1 COM1 Ordering Information Part Number Packaging Type Marking Code Shipping Qty UM2268 QFN10 1.8mm×1.4mm AE UM2268A QFN10 2.1mm×1.6mm AL 3000pcs/7 Inch Tape & Reel Pin Description UM2268 UM2268A Name Function 1,3 2,4 NO1,NO2 Normally-open terminal 10,2 1,3 NC1,NC2 Normally-closed terminal 4 5 GND Ground 8,5 9,6 COM1,COM2 Common terminal 7,6 8,7 IN1,IN2 Digital control pin to connect the COM terminal to the NO or NC terminals 9 10 V+ Power Supply Function Table LOGIC 0 1 NO OFF ON NC ON OFF Absolute Maximum Ratings Symbol V+ VIS VIN ID IP TO TSTG ESD Parameter Supply Voltage Analog Switch Input Voltage Digital Select Input Voltage Continuous DC Current Peak Current Operating Temperature Range Storage Temperature Range HBM Limit 0 to + 4.6 -0.3 to (VCC + 0.3) 0 to + 4.6 250 350 - 40 to +85 - 65 to +150 4000 Unit V mA mA °C V ________________________________________________________________________ http://www.union-ic.com Rev.07 Feb.2014 2/11 UM2268/UM2268A Electrical Characteristics V+ = +4.4V, GND = 0V, TA = -40°C to + 85°C.
