ADG802BRMZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG802BRMZ is a monolithic CMOS single-pole, single-throw (SPST) switch with normally closed configuration. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and supports an automotive temperature range of −40°C to +125°C. The device features a maximum on resistance of 0.4 Ω at 125°C and a maximum on resistance flatness of 0.08 Ω at the same temperature. It handles up to 400 mA of continuous current with switching times of 45 ns (tON) and 15 ns (tOFF). Key electrical parameters include a −3 dB bandwidth of 12 MHz, off isolation of −61 dB, and charge injection of 50 pC. The component is housed in an 8-lead MSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'Z' indicates RoHS compliance as documented in the manufacturer's ordering guide. Confirm the package option corresponds to the 8-Lead Mini Small Outline Package (RM-8). Ensure the part number matches the ADG802 variant which specifies the normally closed switch configuration distinct from the ADG801 model.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring a normally closed analog switch with low on resistance under varying temperatures. The 1.8 V to 5.5 V supply range accommodates various logic levels. Consider the 400 mA current carrying capability for load switching needs. Verify that the 8-lead MSOP package fits the available PCB space constraints compared to the 6-lead SOT-23 alternative.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG802BRMZ belongs to the ADG801/ADG802 family of low on resistance switches manufactured by Analog Devices Inc. It is pin-compatible with the ADG702 model, facilitating design upgrades or replacements. The series utilizes iCMOS technology to achieve high switching speeds and low leakage currents within a compact surface-mount footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG702 is a pin-compatible substitute within the same product family. Both devices share identical pinouts and similar electrical characteristics, allowing for direct replacement in existing designs without schematic modifications.
