ADG822BRMZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG822BRMZ is a monolithic CMOS dual single-pole, single-throw (SPST) switch from Analog Devices. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and supports an analog signal range of 0 V to VDD. The device features a maximum on resistance of 0.8 Ω at 125°C with a typical value of 0.5 Ω. It provides a continuous current carrying capability of 200 mA and exhibits low leakage currents, typically ±0.01 nA. Switching times are characterized by a maximum tON of 45 ns and a maximum tOFF of 16 ns. The component is housed in an 8-lead MSOP package and is designed for automotive temperature ranges from −40°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The BRMZ designation indicates an 8-lead Mini Small Outline Package that is RoHS compliant. Confirm availability status as distribution channels may vary. Ensure the procurement documentation matches the exact part number to avoid confusion with pin-compatible variants like the ADG821 or ADG823 which differ in switch state configurations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG822BRMZ when a dual normally closed SPST switch is required within a 1.8 V to 5.5 V supply environment. Consider this component for applications demanding low on resistance flatness and high current handling up to 200 mA. Verify compatibility with existing logic levels, as the device accepts TTL- and CMOS-compatible inputs. Ensure the thermal requirements align with the specified automotive operating range if deployed in harsh environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG822BRMZ belongs to the ADG82x family of monolithic CMOS switches manufactured by Analog Devices. This series includes the ADG821 and ADG823, which share identical electrical specifications and pinouts but differ in their internal switch states. The ADG822 specifically features two normally closed switches, distinguishing it from the normally open ADG821 and the mixed-state ADG823.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG821BRMZ and ADG823BRMZ are pin-compatible replacements within the same package. Note that the ADG821 contains two normally open switches, while the ADG823 combines one normally open and one normally closed switch with break-before-make action. Direct substitution requires verifying that the specific switch state logic meets the circuit design requirements.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the ADG822 and ADG823?

Both devices share the same electrical characteristics and pinout. The ADG822 contains two normally closed switches, whereas the ADG823 contains one normally open switch and one normally closed switch, exhibiting break-before-make switching action.

Does the ADG822 support bidirectional signal flow?

Yes, each switch conducts equally well in both directions when turned on, allowing the Source and Drain terminals to function interchangeably as inputs or outputs.

What is the maximum continuous current rating?

The ADG822 supports a continuous current of 200 mA per channel. Peak pulsed current can reach 400 mA under specific duty cycle constraints.
