ADG733BRU

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG733BRU is a low voltage, CMOS triple SPDT analog switch manufactured by Analog Devices Inc. It operates on a single supply of 1.8 V to 5.5 V or dual supplies up to ±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 typically 100 pA. Switching times are 19 ns (typical) for turn-on and 7 ns (typical) for turn-off. The part includes a dedicated enable input and guarantees break-before-make switching action. It is housed in a 16-lead TSSOP package and supports industrial temperatures from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and RoHS compliance status. Confirm that the B version temperature range meets the operational requirements. Cross-reference the pinout with the official datasheet outline dimensions to prevent installation errors in the target PCB layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a low-voltage, triple-channel multiplexer is required. Ensure the system supply voltage falls within the 1.8 V to 5.5 V single supply or ±2.5 V dual supply range. Verify that the 4.5 Ω maximum on resistance and 160 MHz bandwidth meet the signal integrity requirements of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG733BRU belongs to the ADG733/ADG734 family of low voltage CMOS switches. It is functionally similar to the ADG734 but contains three SPDT switches instead of four. Both devices share the same enhanced submicron process technology, offering high switching speed and low power dissipation. The BRU suffix indicates the industrial temperature grade and TSSOP package type.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG733BRUZ is a direct replacement offering RoHS compliance while maintaining identical electrical specifications and pinout compatibility. Other members of the ADG73x family may require schematic adjustments due to differing channel counts or control logic configurations.
