_______________General Description
____________________________Features
♦ Upgraded Replacement for a DG211/DG212 Pair
The MAX333A is a precision, quad, single-pole double-
throw (SPDT) analog switch. The four independent
switches operate with bipolar supplies ranging from
±±.ꢀ5 to ±ꢁꢂ5, or with a single-ended supplꢃ between
+1ꢂ5 and +3ꢂ5. The MAX333A offers low on resistance
(less than 3ꢀΩ), guaranteed to match within ꢁΩ between
channels and to remain flat over the analog signal range
(∆3Ω max). It also offers break-before-make switching
(1ꢂns tꢃpical), with turn-off times less than 1±ꢀns and
turn-on times less than 17ꢀns. The MAX333A is ideal for
portable operation since quiescent current runs less
than ꢀꢂµA with all inputs high or low.
or Two DG403s
♦ Low On Resistance < 17Ω Typical (35Ω Max)
♦ Guaranteed Matched On Resistance Between
Channels < 2Ω
♦ Guaranteed Flat On Resistance over Analog
Signal Range ∆3Ω Max
♦ Guaranteed Charge Injection < 10pC
♦ Guaranteed Off-Channel Leakage < 6nA at +85°C
♦ ESD Guaranteed > 2000V per Method 3015.7
♦ Single-Supply Operation (+10V to +30V)
Bipolar-Supply Operation (±4.5V to ±20V)
This monolithic, quad switch is fabricated with Maxim’s
new improved silicon-gate process. Design improvements
guarantee extremelꢃ low charge injection (1ꢂpC), low
power consumption (3.7ꢀmW), and electrostatic discharge
(ESD) greater than ꢁꢂꢂꢂ5.
♦ TTL-/CMOS-Logic Compatibility
♦ Rail-to-Rail Analog Signal Handling Capability
______________Ordering Information
Logic inputs are TTL and CMOS compatible and guaranteed
over a +ꢂ.85 to +ꢁ.±5 range—regardless of supplꢃ voltage.
Logic inputs and switched analog signals can range anꢃ-
where between the supplꢃ voltages without damage.
