Description

Create a design and simulate using EE-Sim^® tools:

The MAX14756/MAX14757/MAX14758 are analog switches with a low on-resistance of 10Ω (max) that conduct equally well in both directions. All devices have a rail-to-rail analog-signal range. They operate with a single +10V to +70V supply in unipolar applications or ±35V dual supplies in bipolar applications. The bipolar supplies can be offset and do not have to be symmetrical.

The MAX14756 is a quad normally closed (NC) single-pole/single-throw (SPST) switch, the MAX14757 is a quad normally open (NO) SPST switch, and the MAX14758 has two NO and two NC SPST switches. These switches have 5Ω (typ) on-resistances and low on-leakage currents of 0.01nA (typ). The on-resistance flatness is 0.004Ω (typ).

The devices are suitable for a multitude of analog signal routing and switching applications. They are specified over an extended temperature range of -40°C to +85°C, but can be operated up to +125°C with elevated leakage currents.
