ADG759BCPZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG759BCPZ is a low-voltage CMOS analog multiplexer featuring four differential channels in a 20-lead LFCSP package. It operates on a single supply of 1.8 V to 5.5 V or dual supplies up to ±2.75 V. Key electrical parameters include a typical ON resistance of 3 Ω (max 4.5 Ω), 100 pA leakage currents, and 14 ns switching times. The device provides 55 MHz bandwidth, –80 dB off isolation at 1 MHz, and consumes less than 0.01 µW power. It supports TTL/CMOS inputs and functions as both a multiplexer and demultiplexer.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm packaging type. The standard suffix indicates tray packaging, while REEL7 denotes tape and reel. Confirm RoHS compliance status for the specific batch. Ensure the temperature grade matches the application requirements. Check for moisture sensitivity levels prior to soldering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when differential signal routing is required in a compact footprint. Compare against the ADG758 if single-ended signals are sufficient. Verify that the 3-bit address lines are not needed, as this part uses 2-bit addressing. Ensure the 4 mm x 4 mm package fits the board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the ADG758/ADG759 family of chip-scale multiplexers. It shares the same physical package and general architecture as the ADG758 but is configured specifically for differential applications. Functionally equivalent versions in TSSOP packages are available as the ADG708 and ADG709 series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG759BCPZ-REEL7 is the tape-and-reel variant of this exact component. For single-ended applications, the ADG758BCPZ serves as the functional counterpart within the same package. Legacy TSSOP equivalents include the ADG709.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG759 handle channel switching?

It utilizes a guaranteed break-before-make switching action, which prevents momentary shorting between channels during transitions.

What is the maximum operating voltage for single-supply mode?

The device supports a single supply voltage range from 1.8 V to 5.5 V.

Can this IC function as a demultiplexer?

Yes, the datasheet specifies that these switches can operate equally well as either multiplexers or demultiplexers.
