ADG787BCPZ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG787BCPZ-REEL7 is a low voltage CMOS device containing two independently selectable single-pole, double-throw (SPDT) switches. It operates on a single supply from 1.8 V to 5.5 V and features a typical on resistance of 2.5 Ω with a maximum of 3.45 Ω at 85°C. The component provides a -3 dB bandwidth of 150 MHz and exhibits extremely low power consumption, typically less than 0.1 μW. It supports USB 1.1 signal switching and includes break-before-make switching action. The device is housed in a 10-lead Lead Frame Chip Scale Package (LFCSP).

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant against the ordering guide, as the ADG787 series includes MSOP, WLCSP, and LFCSP options. Confirm that the B suffix corresponds to the industrial temperature range required for the application. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS structure.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when space-constrained designs require dual analog switches with low distortion. The LFCSP package is ideal for high-density PCB layouts. Consider the 1.8 V to 5.5 V supply range compatibility with the system logic levels. Verify thermal performance if operating near the upper temperature limits.
