ADG1221BRMZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1221BRMZ is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. using iCMOS technology, housed in a 10-lead MSOP package. It operates on supply voltages ranging from ±5 V to ±16.5 V or +5 V to +16.5 V single supply. Key electrical parameters include an on resistance of 120 Ω at ±15 V and 300 Ω at +12 V, with charge injection below 0.5 pC. The device supports rail-to-rail signal ranges, features 3 V logic-compatible inputs, and offers off leakage of 2 pA. Operating temperature range spans from -40°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and check for specific ordering suffixes such as REEL7 if tape and reel packaging is required. Ensure the selected variant matches the necessary logic polarity and thermal requirements for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG1221BRMZ when low charge injection and minimal signal distortion are critical. Compare on resistance values against system requirements for both dual and single supply configurations. Consider the ADG1222 if inverted logic control is preferred, or the ADG1223 for break-before-make switching actions in multiplexer designs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG1221/ADG1222/ADG1223 family of low capacitance, low charge injection switches. All variants share identical physical packages and core iCMOS manufacturing processes but differ in digital control logic inversion and switching timing characteristics to suit specific circuit topologies.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the ADG1222BRMZ and ADG1223BRMZ. Verify pin compatibility and logic level requirements before substitution. Cross-family replacements require careful evaluation of on resistance, leakage currents, and package dimensions.
