The MAX351/MAX352/MAX353 are precision, quad,
single-pole single-throw (SPST) analog switches. The
MAX351 has four normally closed (NC), and the MAX352
has four normally open (NO) switches. The MAX353 has
two NO and two NC switches. All three parts offer low on
resistance (less than 35Ω), guaranteed to match within 2Ω
between channels and to remain flat over the analog signal
range (∆3Ω max). They also offer low leakage (less than
250pA at +25°C and less than 6nA at +85°C) and fast
switching (turn-on time less than 175ns and turn-off time
less than 145ns).
The MAX351/MAX352/MAX353 are fabricated with Maxim’s
new improved 44V silicon-gate process. Design improve-
ments guarantee extremely low charge injection (10pC), low
power consumption (35µW), and electrostatic discharge
(ESD) greater than 2000V. The 44V maximum breakdown
voltage allows rail-to-rail analog signal handling.
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.
