ADG734BRUZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG734BRUZ is a low voltage CMOS quad SPDT analog switch in a 20-lead TSSOP package. It operates on a single supply of 1.8 V to 5.5 V or dual supplies up to ±2.5 V. The device features a typical on resistance of 2.5 Ω with a maximum of 4.5 Ω, and an on resistance flatness of 0.5 Ω. Leakage currents are typically 100 pA. Switching times are 19 ns (typical) for turn-on and 7 ns (typical) for turn-off. The -3 dB bandwidth reaches 160 MHz at 5 V and 200 MHz at ±2.5 V. Power consumption is extremely low, with supply current typically 0.001 µA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The 'Z' suffix indicates RoHS compliance. Confirm the tube quantity matches project requirements, as reel options exist. Ensure the industrial temperature range (-40°C to +85°C) aligns with environmental constraints. Cross-reference the datasheet revision to ensure all electrical specifications match design assumptions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent SPDT switches are required in a compact surface-mount footprint. The low on resistance and flatness make it suitable for precision signal routing. Verify that the input signal range remains within the supply rails. Consider the ADG733 if only three channels are needed, or check for higher channel count alternatives if more than four switches are required.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG733/ADG734 family of low voltage CMOS switches. The ADG733 variant offers three channels in a 16-lead package, while the ADG734 provides four channels in a 20-lead package. Both share identical electrical characteristics and pinout compatibility for their respective channel counts, facilitating design scalability within the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other ADG734 variants such as ADG734BRU or ADG734BRUZ-REEL, which share the same electrical specifications and pin configuration but differ in packaging format.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum analog signal range for the ADG734BRUZ?

In single supply mode, the analog signal range extends from 0 V to VDD. In dual supply mode, it ranges from VSS to VDD.

Does the ADG734BRUZ support simultaneous make-before-break switching?

No, the device is designed with guaranteed break-before-make switching action to prevent momentary shorting between channels during transitions.

How does the on resistance vary with the analog signal voltage?

The on resistance is typically 2.5 Ω and exhibits a flatness of 0.5 Ω over the full signal range, ensuring minimal variation regardless of the input voltage level.
