Description
19-1396; Rev 0; 10/98 High-Voltage, Single 8-to-1/ Dual 4-to-1 Cal-Multiplexers General .
The MAX4578/MAX4579 are high-voltage, 8-channel CMOS multiplexers.
Features
* o On-Chip Gain and Offset Divider Networks Provide 15-Bit Accurate Output Ratios o On-Chip V+ to GND and V+ to V- Divider Networks Provide 8-Bit Accurate Output Ratios o 350Ω (max) RON o 12Ω (max) RON Matching Between Channels o 10pC (max) Charge Injection o Guaranteed 20pA Off-Leakage Current o Rai
Applications
* These calibration multiplexers (cal-muxes) have precision resistordividers to generate accurate voltage ratios from an input reference voltage. The reference ratios include 15/4096 and 4081/4096 of the external reference voltage, accurate to 15 bits, and 1/2(V+) and 5/8(V+ - V-), accurate to 8 bits
