AD8187ARU-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The AD8187ARU-REEL is a high-speed, single-supply triple 2:1 multiplexer with a fixed gain of +2 V/V. It features a –3 dB large signal bandwidth exceeding 480 MHz and a slew rate greater than 1500 V/µs. The device operates on a single 5 V supply, consuming approximately 19 mA to 20 mA. Key electrical specifications include a channel-to-channel switching time of 4 ns, an enable-to-channel ON time of 3.8 ns, and an off isolation of –95 dB at 5 MHz. It provides excellent video performance with differential gain and phase errors of 0.05% and 0.05°, respectively.

• High-speed data acquisition systems requiring rapid channel selection.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific reel length (e.g., 7-inch or 13-inch) as indicated by the suffix, since the base part number covers multiple packaging options. Confirm that the application design accounts for the obsolete status of this component family. Ensure proper ESD handling procedures are followed during assembly, as the device is sensitive to electrostatic discharge. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match the intended design requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the AD8187 when a fixed voltage gain of two is required alongside multiplexing functionality. This device is suitable for applications needing high dynamic range and low glitch energy during channel transitions. Consider the AD8186 if unity gain is preferred instead. Evaluate the single-supply operation constraints, particularly the VREF biasing requirements for optimal output swing. Ensure the load impedance matches the specified conditions for accurate crosstalk and bandwidth performance.
