Description

Features, Applications

Maxim's redesigned DG417/DG418/DG419 precision, CMOS, monolithic analog switches now feature guaranteed on-resistance matching (3 max) between switches and guaranteed on-resistance flatness over the signal range (4 max). These switches conduct equally well in either direction and guarantee low charge injection, low power consumption, and an ESD tolerance of 2000V minimum per Method 3015.7. The new design offers low off-leakage current over temperature (less than at +85�C). The DG417/DG418 are single-pole/single-throw (SPST) switches. The DG417 is normally closed, and the DG418 is normally open. The DG419 is singlepole/double-throw (SPDT) with one normally closed switch and one normally open switch. Switching times are less than 175ns max for tON and less than 145ns max for tOFF. Operation is from a single to +30V supply, or bipolar to �20V supplies. The improved DG417/DG418/DG419 are fabricated with a 44V silicon-gate process.

o Plug-In Upgrades for Industry-Standard DG417/DG418/DG419 o Improved RDS(ON) Match Between Channels (3 max, DG419 only) o Guaranteed RFLAT(ON) Over Signal Range (4 max) o Improved Charge Injection (10pC max) o Improved Off-Leakage Current Over Temperature +85�C) o Withstand Electrostatic Discharge (2000V min) per Method 3015.7

o Low RDS(ON) (35 max) o Single-Supply Operation to +30V Bipolar-Supply Operation �20V o Low Power Consumption (35�W max) o Rail-to-Rail Signal Handling o TTL/CMOS-Logic Compatible

Note 1: Signals or IN exceeding or V- are clamped by internal diodes. Limit forward current to maximum current ratings.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

(V+ = 5V, GND = 0V, VINL = 0.8V, VINH TA = TMIN to TMAX, unless otherwise noted.)
