ADG1519BCPZ-RL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1519BCPZ-RL7 is a single-pole, double-throw (SPDT) analog switch manufactured by Analog Devices Inc. It features a typical on-resistance of 3.8 Ω and a maximum of 5.2 Ω at 25°C. The device operates with asymmetrical dual supplies: VDD from +4.5 V to +5.5 V and VSS from -4.5 V to -8.8 V. It supports continuous current up to 310 mA per channel and offers rail-to-rail signal handling. Key electrical parameters include –98 dB total harmonic distortion, 95 MHz –3 dB bandwidth, and 60 dB off-isolation at 1 MHz. The component is housed in an 8-lead, 2 mm × 3 mm LFCSP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix RL7 indicates reel packaging with a quantity of 3000 units. Confirm RoHS compliance status marked by the Z suffix. Ensure the temperature range matches the application requirements of -40°C to +125°C. Check for lead-free soldering compatibility as specified in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when asymmetrical bipolar supplies are available, specifically requiring negative bias voltages down to -8.8 V. It is suitable for applications needing high linearity and low THD. Consider the 8-lead LFCSP package constraints for PCB layout. Verify that the 3 V logic interface meets the system control voltage requirements without additional level shifting.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG1519 series of SPDT switches designed for RF and audio signal routing. It is distinct from other ADI switches by its specific focus on power amplifier gate drive capabilities using asymmetrical supplies. The CP-8-31 package variant defines its physical footprint and thermal characteristics.
