ADG1221BRMZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1221BRMZ-REEL7 is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. It utilizes iCMOS technology to support supply voltages up to ±16.5 V or +16.5 V single supply. The device features an on resistance of 120 Ω typical and 200 Ω maximum at ±15 V, with off capacitance limited to 2 pF. Charge injection is specified at less than 0.5 pC over the full signal range. Digital inputs are compatible with 3 V logic levels. The component operates within a temperature range of -40°C to +125°C and is housed in a 10-lead MSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix REEL7 indicates reel packaging when sourcing components. Confirm the specific part number matches the required logic configuration for the ADG1221 series. Ensure the manufacturer documentation aligns with the requested specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low charge injection and high bandwidth. Compare against ADG1222 if inverted digital control logic is preferred. Verify that the 10-lead MSOP package dimensions fit the target PCB layout constraints. Check thermal resistance requirements for the intended operating environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG1221/ADG1222/ADG1223 family of low capacitance switches. The ADG1221 variant specifically provides non-inverted digital control logic for its two independent SPST switches. It shares the same physical package and core electrical characteristics as the other family members, differing primarily in internal logic gating.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1222BRMZ serves as a functional alternative with inverted logic control. The ADG1223BRMZ offers break-before-make switching action suitable for multiplexer configurations. All variants share identical pinouts and mechanical dimensions.
