ADG2436BCPZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG2436BCPZ-REEL7 is a dual single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc. It features a low on-resistance of 0.5 Ω and supports supply voltages ranging from ±4.5 V to ±16.5 V for dual supplies, or +5 V to +16.5 V for single supplies. The device operates with asymmetric power supplies and includes logic compatibility for 1.8 V, 3.3 V, and 5 V inputs without requiring a separate logic supply pin. Packaged in a 16-lead, 4 mm × 4 mm Lead Frame Chip Scale Package (LFCSP), it offers high continuous current capability up to 847 mA per channel under specific conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the RoHS compliance status indicated by the 'Z' suffix in the part number against current manufacturer documentation. Confirm that the LFCSP package dimensions and thermal requirements align with the printed circuit board design specifications. Ensure proper electrostatic discharge precautions are observed during handling due to the sensitivity of the CMOS structure.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low on-resistance and high linearity in signal routing. Consider the voltage headroom limitation where the analog signal range extends only to VDD minus 2 V. Evaluate the thermal resistance characteristics if operating at high continuous currents or elevated ambient temperatures within the specified -40°C to +125°C range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG2436 series of dual SPDT analog switches. It is designed as a pin-to-pin compatible replacement for the ADG1436, offering improved balance between on-resistance and on-capacitance. The series supports various supply configurations, making it versatile for different system architectures requiring precise signal switching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1436 is explicitly documented as a pin-to-pin compatible alternative within the same product family. Verify that the electrical specifications of the substitute meet the specific requirements for on-resistance, leakage current, and supply voltage ranges required by the application.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum analog signal voltage range for the ADG2436?

The analog signal range extends from VSS to VDD minus 2 V. For optimal performance regarding on-resistance and distortion, it is recommended that the signal stays less than VDD minus 3.5 V.

Does the ADG2436 require a separate logic supply voltage (VL)?

No, the ADG2436 does not require a separate VL logic power supply pin. The digital inputs are compatible with 1.8 V, 3.3 V, and 5 V logic levels over the full operating supply range.

How does the ADG2436 handle switching in multiplexer applications?

Both switches exhibit break-before-make switching action. This feature ensures that one switch turns off before the other turns on, which is critical for multiplexer applications to prevent shorting inputs together during state transitions.
