ADG733BRQ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG733BRQ is a triple single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 1.8 V to 5.5 V or a dual supply of ±2.5 V. The device features a typical on resistance of 2.5 Ω with a maximum of 4.5 Ω at 5 V, and an on resistance flatness of 0.5 Ω. Leakage currents are specified at ±0.1 nA maximum. Switching times include a typical turn-on time of 19 ns and turn-off time of 7 ns at 3 V. The -3 dB bandwidth reaches 160 MHz at 5 V and 200 MHz at ±2.5 V. It is housed in a 16-lead QSOP package and functions within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type, as BRQ denotes the QSOP variant. Confirm RoHS compliance status if required for environmental regulations. Check current availability through authorized distributors, as stock levels fluctuate. Ensure the operating voltage range matches the system design constraints before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when three independent SPDT switches are required in a compact form factor. The low on resistance and high bandwidth make it suitable for precision signal routing. Consider the 16-lead QSOP package for space-constrained PCB layouts. Verify that the digital control logic levels align with the TTL/CMOS compatibility specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG733BRQ belongs to the ADG733/ADG734 family of low voltage CMOS switches. While the ADG733 contains three SPDT switches, the ADG734 variant offers four channels. Both share similar electrical characteristics and are designed for portable applications requiring low power dissipation and high switching speed.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other Analog Devices triple SPDT switches such as the ADG733BRU or ADG733BRUZ. Cross-family replacements like the ADG713 series offer quad SPST configurations but differ in pinout and channel count. Verify pin compatibility and electrical parameters before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the function of the EN pin on the ADG733?

The EN pin is an active-low device enable input. When driven low, all channels are switched OFF, disabling the device regardless of the address inputs.

Does the ADG733 support dual supply operation?

Yes, the device supports dual supply operation with a typical configuration of ±2.5 V, allowing the analog signal range to extend from VSS to VDD.

What is the maximum continuous current rating for the switch terminals?

The maximum continuous current for either the Source (S) or Drain (D) terminal is 30 mA.
