19-1505; Rev 0; 7/99 Ω 2.5 , Dual, SPST, CMOS Analog Switches General Description Features M The MAX4667/MAX4668/MAX4669 dual analog switches 'Low On-Resistance (2.5Ωmax) A feature low on-resistance of 2.5Ω max. On-resistance is matched between switches to 0.5Ωmax and is flat (0.5Ω 'Guaranteed RONMatch Between Channels X max) over the specified signal range. Each switch can (0.5Ωmax) 4 handle Rail-to-Rail® analog signals. The off-leakage cur- 'Guaranteed RONFlatness over Specified Signal 6 rent is only 5nA max at +85°C. These analog switches Range (0.5Ωmax) 6 are ideal in low-distortion applications and are the pre- ferred solution over mechanical relays in automatic test 'Guaranteed Break-Before-Make (MAX4669) 7 equipment or applications where current switching is 'Rail-to-Rail Signal Handling /M required. They have low power requirements, use less board space, and are more reliable than mechanical 'Guaranteed ESD Protection >2kV A relays. per Method 3015.7 X The MAX4667 has two normally closed (NC) switches, '+4.5V to +36V Single-Supply Operation 4 the MAX4668 has two normally open (NO) switches, ±4.5V to ±20V Dual-Supply Operation 6 and the MAX4669 has one NC and one NO switch that guarantee break-before-make operation. 'TTL/CMOS-Compatible Control Inputs 6 8 These switches operate from a +4.5V to +36V single supply or from ±4.5V to ±20V dual supplies.
