ADG619BRM

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG619BRM is a monolithic CMOS single-pole double-throw (SPDT) switch featuring a maximum on resistance of 6.6 Ω and on-resistance flatness of 0.8 Ω. It operates on a single supply from 2.7 V to 5.5 V or dual supplies from ±2.7 V to ±5.5 V, supporting rail-to-rail signal ranges. Key dynamic parameters include a typical turn-on time of 120 ns, turn-off time of 75 ns, off isolation of −67 dB at 1 MHz, and bandwidth of 190 MHz. The device draws a maximum supply current of 1.0 μA and functions within an industrial temperature range of −40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant, as the ADG619 family includes both MSOP and SOT-23 options. Confirm RoHS compliance status via the ordering guide suffixes. Ensure the selected version matches the required thermal impedance and pin configuration for the target PCB layout. Cross-reference the manufacturer's latest datasheet revision for any specification updates.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG619BRM for applications requiring low on resistance and fast switching speeds in compact designs. Choose the MSOP package for standard surface-mount assembly or SOT-23 for space-constrained layouts. Ensure the analog signal range remains within the supply rails. Verify that the break-before-make timing meets system requirements to avoid cross-conduction.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG619 belongs to Analog Devices' family of low-voltage CMOS analog switches. It is designed for general-purpose signal routing where low distortion and high speed are critical. The component serves as a direct replacement for mechanical relays in battery-powered and portable instrumentation due to its solid-state reliability and minimal power draw.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other ADI SPDT switches such as the ADG620 or ADG619 variants with different packaging. When replacing, verify that the on resistance, leakage currents, and operating voltage ranges are compatible with the existing circuit design.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the break-before-make time delay for the ADG619?

The break-before-make time delay is typically 40 ns under dual supply conditions and 70 ns under single supply conditions, ensuring no momentary shorting occurs between channels.

How does the ADG619 handle ESD sensitivity?

The device is ESD sensitive and features internal protection circuitry. Proper ESD precautions should be taken during handling to avoid performance degradation, although it is not immune to high-energy discharge damage.

Can the ADG619 operate with a single supply?

Yes, the ADG619 supports single-supply operation from 2.7 V to 5.5 V. In this mode, the VSS pin must be tied to ground.
