ADG1409YCPZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1409YCPZ-REEL7 is a monolithic iCMOS analog multiplexer featuring four differential channels. It switches one of four differential inputs to a common differential output using two-bit binary address lines (A0, A1) and an active-high enable pin (EN). The device supports fully specified operation at ±15 V, +12 V, and ±5 V supplies with rail-to-rail signal handling. Key electrical parameters include a maximum on-resistance of 4.7 Ω at 25°C, 0.5 Ω on-resistance flatness, and a -3 dB bandwidth of 115 MHz under dual supply conditions. It operates within an industrial temperature range of -40°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• iCMOS modular manufacturing process enables high voltage tolerance up to 33 V while maintaining low power consumption and small package size.
• Ultralow on-resistance and high flatness make the switch ideal for data acquisition and gain switching applications requiring low distortion.
• Rail-to-rail operation allows analog signals to span the full supply voltage range from VSS to VDD.
• Break-before-make switching action prevents short circuits during channel transitions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official documentation. Confirm the specific suffix 'Y' corresponds to the industrial temperature grade (-40°C to +125°C) required for your application environment. Ensure the LFCSP package exposed pad is properly soldered to the substrate for thermal performance and reliability as recommended in the datasheet guidelines.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when differential signal routing is required with high bandwidth and low distortion. The ADG1409 provides four differential channels, whereas the ADG1408 offers eight single-ended channels. Consider the 4.7 Ω maximum on-resistance and 115 MHz bandwidth specifications to ensure compatibility with your signal frequency and impedance requirements. Verify that the 3 V logic-compatible inputs align with your microcontroller or FPGA control levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG1409 belongs to the Analog Devices ADG14xx series of high-performance iCMOS multiplexers. It shares the same core architecture and manufacturing process as the ADG1408 but differs in channel configuration, offering four differential channels instead of eight single-ended ones. This family utilizes industrial CMOS technology to achieve high voltage capability and low power dissipation in compact packages like the 16-lead LFCSP.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1408YCPZ-REEL7 is a related device in the same family but provides eight single-ended channels rather than four differential channels. Direct substitution requires verifying if the application can accommodate single-ended signaling or if additional circuitry is needed to convert differential signals. Other ADG14xx variants may offer different channel counts or packaging options but share similar electrical characteristics.
