ADG333ABR

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG333ABR is a monolithic CMOS device comprising four independently selectable single-pole, double-throw (SPDT) switches. It operates from dual supplies of ±3 V to ±20 V or a single supply of 3 V to 30 V. Key electrical parameters include a maximum on-resistance of 45 Ω, a maximum ∆Ron of 5 Ω, and a maximum Ron match of 4 Ω. Switching times are specified with tON max at 175 ns and tOFF max at 145 ns. The device features low leakage currents of 5 nA max and charge injection of 10 pC max.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package option required, as the ADG333ABR designation corresponds to the 20-Lead Standard Small Outline Package (SOIC). Confirm RoHS compliance status if environmental regulations apply, noting that suffixes like 'Z' indicate RoHS compliant parts while others may not be. Ensure the ordering suffix matches the desired reel or tube packaging configuration defined in the manufacturer's ordering guide.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an extended analog signal range up to the supply rails is required. The device supports both single-supply and dual-supply configurations, offering flexibility for unipolar or bipolar signal processing. Consider the 45 Ω maximum on-resistance and 175 ns switching speed for applications requiring moderate linearity and speed without the complexity of higher-performance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG333ABR belongs to the ADG333A family of quad SPDT analog switches manufactured by Analog Devices. This series utilizes linear compatible CMOS technology to balance low power consumption with high switching speeds. The AB variant specifically denotes the industrial temperature grade ranging from -40°C to +85°C, distinguishing it from commercial or military grade options within the broader product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include the MAX333ACWP and DG333ADQ-T1-E3. These devices offer similar quad SPDT functionality but may differ in package type, such as SOIC or TSSOP, and specific electrical characteristics like on-resistance or operating voltage ranges. Verify pin compatibility and thermal performance before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

Can the ADG333ABR operate with unbalanced dual supplies?

Yes, the device can operate with unbalanced supplies, provided VDD to GND does not exceed 30 V, VSS to GND does not drop below -30 V, and VDD to VSS does not exceed 44 V.

What is the recommended power supply sequencing for the ADG333ABR?

To prevent overstress, always turn on VDD first, followed by VSS and the logic signals. An external signal can then be safely presented to the source or drain.

Does the ADG333ABR exhibit break-before-make switching?

Yes, all switches exhibit break-before-make switching action, which is beneficial for use in multiplexer applications to prevent short circuits between channels.
