MAX4518

19-1070; Rev. 1; 5/98 Precision, 4-Channel/Dual 2-Channel, Low-Voltage, CMOS Analog Multiplexers ________________General Description The MAX4518/MAX4519 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 100 Ω ), which is matched to within 4 Ω between channels and remains flat over the specified analog signal range (10Ω max). They also offer low leakage over temperature (NO-off leakage current less than 2nA at +85°C) and fast switching speeds (transition time less than 250ns). The MAX4518 is a 4-channel device, and the MAX4519 is a dual 2-channel device. The MAX4518/MAX4519 are fabricated with Maxim’s low-voltage silicon-gate process. Design improvements yield extremely low charge injection (less than 5pC) and guarantee electrostatic discharge protection greater than 2000V. These muxes operate with a single +2.7V to +15V supply or with bipolar ±2.7V to ±8V supplies, while retaining CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading. ____________________________Features o Guaranteed On-Resistance Match Between Channels (<4Ω ) o Low On-Resistance (<100Ω ) o Guaranteed Flat On-Resistance over Signal Range (<10Ω) o Guaranteed Low Charge Injection (<5pC) o NO-Off Leakage Current <2nA at +85°C o COM-Off Leakage Current <5nA at +85°C o Electrostatic Discharge Protection >2000V o Single-Supply Operation (+2.7V to +15V) Bipolar-Supply Operation (±2.7V to ±8V) o Low Power Consumption (<300µW) o Rail-to-...
