ADG1439BCPZ-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1439BCPZ-REEL7 is a dual 4-channel iCMOS matrix switch featuring a serially controlled 3-wire interface. It supports ±15 V, +12 V, and ±5 V supplies with rail-to-rail signal handling. The device offers a 9.5 Ω typical on-resistance at 25°C and 1.6 Ω flatness. It operates with 3 V logic-compatible inputs and includes an SDO daisy-chaining option for cascading up to 50 MHz. Available in 20-lead LFCSP (4 mm × 4 mm) packaging, it ensures ultralow power dissipation suitable for portable applications.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Serially controlled 3-wire interface compatible with SPI, QSPI, MICROWIRE, and DSP standards
• Rail-to-rail operation with fully specified performance across ±15 V, +12 V, and ±5 V supply ranges
• Ultralow power dissipation enabled by iCMOS construction for battery-powered systems
• Break-before-make switching action prevents momentary shorting during channel transitions

Analog Switches, Multiplexers, Demultiplexers Applications

• Avionics

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm that the B-grade temperature range (-40°C to +125°C) aligns with system requirements. Ensure ESD precautions are observed during handling due to the sensitivity of CMOS input structures.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact dual 4-channel multiplexer with serial control is required. The LFCSP package provides a small footprint ideal for space-constrained designs. Verify that the 3 V logic compatibility matches the host controller's voltage levels and that the 50 MHz serial clock speed meets data throughput needs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG1438/ADG1439 family of iCMOS analog matrix switches. While the ADG1438 provides an 8-channel configuration, the ADG1439 offers two independent 4-channel matrices within the same pinout and interface architecture. Both share identical electrical characteristics and control protocols.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1438BCPZ-REEL7 serves as a functional substitute if eight channels are required instead of four, maintaining identical pinouts and serial interface compatibility.
