MAX333AEWP+

The MAX333AEWP+ is a precision, quad, single-pole double-throw (SPDT) analog switch from Analog Devices. It is designed for applications requiring high precision and low power consumption.

This monolithic switch operates with bipolar supplies ranging from ±4.5V to ±20V, or with a single-ended supply between +10V and +30V. It offers low on-resistance, typically 45Ω, guaranteed to match within 2Ω between channels and remain flat over the analog signal range (Δ3Ω max). The device provides break-before-make switching with turn-off times less than 145ns and turn-on times less than 175ns.

Fabricated with Maxim's improved silicon-gate process, the MAX333A guarantees extremely low charge injection (10pC), low power consumption (3.75mW), and electrostatic discharge (ESD) protection greater than 2000V. Logic inputs are TTL and CMOS compatible and guaranteed over a +0.8V to +2.4V range, regardless of supply voltage. Analog signals can range between the supply voltages without damage.

The MAX333AEWP+ is available in a 20-SOIC package and is suitable for surface mount applications. Its operating temperature range is -40°C to +85°C. Applications include test equipment, communications systems, PBX/PABX, heads-up displays, and portable instruments.
