ADGS1212BCPZ-RL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADGS1212BCPZ-RL7 is a quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. It features an SPI interface with error detection and operates on dual supplies from ±4.5 V to ±16.5 V or a single supply from 5 V to 16.5 V. The device utilizes iCMOS construction for ultralow power dissipation. Key electrical parameters include a maximum on-resistance of 190 Ω at ±15 V and 625 Ω at +12 V, typical off capacitance of 1 pF, and charge injection under 1 pC. Switching times are typically 375 ns on and 125 ns off at ±15 V. It supports 1.8 V logic compatibility and operates within a temperature range of -40°C to +125°C in an LFCSP-24 package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix BC indicates the commercial grade temperature range and CPZ denotes the LFCSP-24 package configuration. Confirm RL7 specifies the reel packaging format. Ensure the source document matches the manufacturer's official datasheet for the ADGS1212 series to validate all electrical specifications and pinout definitions before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low charge injection and high bandwidth are critical for signal integrity. The SPI interface reduces GPIO usage compared to parallel control schemes. Verify that the required logic voltage level falls within the 2.7 V to 5.5 V range for VL. Consider thermal resistance characteristics if multiple switches are active simultaneously in high-current applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADGS1212 family of low capacitance, low charge injection iCMOS quad SPST switches. It shares functional similarities with other ADI analog switches but is distinguished by its robust SPI error detection capabilities and mux-configurable architecture via external wiring. The family targets precision signal routing in portable and battery-powered instruments due to its ultralow power consumption.
