Precision, Dual, High-Speed Analog Switches  
1/MAX305  
General Description  
Features  
The MAX301/MAX303/MAX305 are precision, dual, high-  
speed analog switches. The single-pole single-throw  
(SPST) MAX301 and double-pole single-throw (DPST)  
MAX305 dualswitches are normally open (NO). The sin-  
gle-pole double-throw (SPDT) MAX303 has two NO and  
two normally closed (NC) poles. All three parts offer low  
on resistance (less than 35Ω), guaranteed to match to  
within 2Ω between channels and to remain flat over the  
full analog signal range (Δ3max). They also offer low leak-  
age (less than 250pA at +25°C and less than 6nA at  
+85°C) and fast switching (turn-on time less than 150ns  
and turn-off time less than 100ns).

Channels < 2Ω

Signal Range Δ3Ω Max  
Guaranteed Charge Injection < 15pC  
Guaranteed Off-Channel Leakage < 6nA at +85°C  
Single-Supply Operation (+10V to +30V)  
Bipolar-Supply Operation (±±45V to ±20V)  
TTL-/CMOS-Logic Compatible  
The MAX301/MAX303/MAX305 are fabricated with  
Maxim’s new improved silicon-gate process for high  
system accuracy. Design improvements guarantee  
extremely low charge injection (15pC) and low power  
consumption (35µW). A 44V maximum breakdown volt-  
age allows rail-to-rail analog signal capability.

TEMP RANGE  
These monolithic switches operate with a single positive  
supply (+10V to +30V) or with split supplies ( 4.5V  
to 20V) while retaining CMOS-logic input compatibility  
and fast switching. CMOS inputs provide reduced input  
loading.
