ADG709BRU-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG709BRU-REEL7 is a low voltage, CMOS analog multiplexer featuring four differential channels. It operates on a single supply of 1.8 V to 5.5 V or dual supplies of ±2.5 V. Key electrical parameters include a typical on resistance of 3 Ω with 0.75 Ω flatness, leakage currents of 100 pA, and switching times of 14 ns. The device offers a 55 MHz bandwidth, -80 dB off isolation at 1 MHz, and charge injection of ±3 pC. It functions as a demultiplexer and supports TTL/CMOS compatible inputs within a 16-lead TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and compliance status. The REEL7 suffix indicates tape and reel packaging configuration. Confirm that the B version temperature range (-40°C to +125°C) meets the operational requirements of the target environment. Cross-reference the part number with official distributor catalogs to ensure availability and correct component identification before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG709BRU-REEL7 when differential signal routing is required in space-constrained designs. The 16-lead TSSOP package provides a compact footprint compared to larger alternatives. Ensure the system voltage aligns with the 1.8 V to 5.5 V single-supply or ±2.5 V dual-supply specifications. Consider the 55 MHz bandwidth and 14 ns switching speed for high-frequency signal integrity requirements in multiplexed environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the Analog Devices ADG708/ADG709 family of low voltage CMOS multiplexers. While the ADG708 provides eight single-ended channels, the ADG709 variant specifically offers four differential channels. Both share identical pinouts, control logic, and electrical characteristics, differing only in channel configuration. The family is designed for applications requiring low power dissipation and high switching speed in small packages.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG709CRUZ-REEL7 serves as a direct functional substitute within the same product family, offering identical electrical performance and pin compatibility. Designers should verify that the C version meets the specific temperature range and reliability requirements of the application. No external circuit modifications are typically required when swapping between these variants due to their shared architecture.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG709 handle channel switching to prevent signal glitches?

The device features guaranteed break-before-make switching action. This ensures that the previous channel is fully disconnected before the new channel connects, preventing momentary shorting between inputs during transitions.

What is the maximum analog signal range for the ADG709?

In single-supply mode, the analog signal range extends from ground (VSS) to the positive supply rail (VDD). In dual-supply mode, it ranges from VSS to VDD, allowing the switch to handle signals extending to the supply rails.

Can the ADG709 operate with digital logic levels other than standard CMOS?

Yes, the ADG709 has TTL- and CMOS-compatible digital inputs. The input voltage thresholds are defined such that they can interface directly with various standard logic families without additional level shifting components.
