_______________General Description ____________________________Features
The MAX333A is a precision, quad, single-pole double- Upgraded Replacement for a DG211/DG212 Pair or Two DG403s
throw (SPDT) analog switch. The four independent
switches operate with bipolar supplies ranging from Low On Resistance < 17Ω Typical (35Ω Max)
±4.5V to ±20V, or with a single-ended supply between Guaranteed Matched On Resistance Between +10V and +30V. The MAX333A offers low on resistance Channels < 2Ω (less than 35Ω), guaranteed to match within 2Ω between
Guaranteed Flat On Resistance over Analog
channels and to remain flat over the analog signal range Signal Range ∆3Ω Max (∆3Ω max). It also offers break-before-make switching
Guaranteed Charge Injection < 10p C
