MAXIM MAX4503 MAX4504 Low- Voltage, Dual-Supply, SPST, CMOS Analog Switches Data Sheet User Manual
Summary
These miniature CMOS Analog Switches (MAX4503/MAX4504) provide reliable, low-voltage signal routing in single-pole, single-throw configurations. Designed for demanding applications like data acquisition systems and communication circuits, they operate efficiently with dual power supplies, featuring extremely low off-leakage currents and fast switching speeds while remaining CMOS-logic compatible. This technical manual provides comprehensive details on operating parameters, package variations, and rigorous electrical specifications necessary for engineers designing portable, battery-operated electronics across diverse temperature ranges.

General Description ____________________________Features
The MAX4503/MAX4504 are low-voltage, dual-supply, Available in SOT23-5 Package single-pole/single-throw (SPST), CMOS analog switch-

es. The MAX4503 is normally open (NO). The MAX4504
Guaranteed On-Resistance:
is normally closed (NC).
250Ω with ±5V Supplies
These CMOS switches can operate continuously with
Guaranteed Low Off-Leakage Currents:
dual supplies between ±1.V and ±6V. Each switch can
1n A at +25°C
handle rail-to-rail analog signals. The off-leakage cur-
10n A at +85°C
rent is only 1n A at +25°C or 10n A at +85°C.
Guaranteed Low On-Leakage Currents:
The digital input is CMOS-logic compatible when using
±5V supplies. A unique logic input architecture allows 2n A at +25°C this even though the parts have no ground pin. 20n A at +85°C For single-supply operation, use the MAX4501/ Guaranteed Low Charge Injection: 10p C Max
MAX4502, which are pin-for-pin equivalents. Fast Switching Speed: t ON = 150ns, t OFF = 100ns

Frequently Asked Questions
What is the operational difference between MAX4503 and MAX4504?
The MAX4503 is normally open (NO), while the MAX4504 is normally closed (NC).
What supply voltage range do these CMOS switches require?
They are designed for dual-supply operation between ±1V and ±6V.
If I only have a single power rail, what switches should I use instead?
For single-supply operation, you must use the pin-for-pin equivalent MAX4501 or MAX4502.
What is the guaranteed maximum on-resistance?
The parts guarantee an On-Resistance of 250 Ω with ±5V supplies.
