ADG1636BCPZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1636BCPZ-REEL7 is a monolithic CMOS device containing two independently selectable single-pole/double-throw (SPDT) switches. It operates on dual supplies from ±3.3 V to ±8 V or single supplies from 3.3 V to 16 V without requiring a separate logic supply. The device features a typical on resistance of 1 Ω and maximum on resistance of 1.6 Ω over temperature. It supports continuous channel currents up to 385 mA in the LFCSP package. Key electrical parameters include an off isolation of 70 dB, total harmonic distortion plus noise of 0.007%, and a -3 dB bandwidth of 25 MHz.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix REEL7 confirms the reel packaging format required for automated assembly processes. Confirm that the BC prefix indicates the industrial temperature grade (-40°C to +125°C). Ensure the LFCSP package option CP-16-26 matches the target footprint dimensions and exposed pad connection requirements for proper thermal and electrical grounding.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on resistance and high linearity are critical for signal integrity. The absence of a VL logic supply simplifies board design compared to other switch families. Verify that the 3 V logic-compatible inputs align with the system's control voltage levels. Consider the LFCSP package for superior thermal performance if higher continuous current handling is necessary.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG1636 series of dual SPDT analog switches manufactured by Analog Devices. It is functionally identical to the ADG1636BRUZ but utilizes the 16-lead Lead Frame Chip Scale Package (LFCSP) instead of the TSSOP. The REEL7 suffix denotes the standard tape and reel quantity used for surface-mount manufacturing.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1636BRUZ serves as the direct pin-compatible alternative using the TSSOP-16 package. Designers must account for differences in thermal impedance and physical footprint dimensions between the LFCSP and TSSOP options during PCB layout modifications.

Analog Switches, Multiplexers, Demultiplexers FAQ

Does the ADG1636 require a separate logic supply voltage?

No, the device does not require a VL logic supply. It features 3 V logic-compatible digital inputs that operate directly from the main power rails.

What is the maximum continuous current per channel for the LFCSP package?

The maximum continuous current per channel for the LFCSP package is 385 mA at 25°C, decreasing to 105 mA at 125°C junction temperature.

How does the device handle switching transitions?

Both switches exhibit break-before-make switching action, which prevents short circuits during state changes and makes the device suitable for multiplexer applications.
