ADG511BN

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG511BN is a monolithic CMOS IC containing four independently selectable analog switches, fabricated using Analog Devices' LC2MOS process. It supports single +3 V, +5 V or ±5 V bipolar supplies with ultralow power dissipation under 0.5 µW and low leakage below 100 pA. The device features low on resistance of less than 50 Ω, fast switching times, and low charge injection. Digital inputs are TTL/CMOS compatible, and the package is a 16-lead Plastic DIP.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. The BN suffix indicates a 16-lead Plastic DIP package with an industrial temperature range of -40 °C to +85 °C. Confirm that the digital control logic matches the application requirements, as the ADG511 uses inverted logic compared to other variants in the family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG511 when inverted digital control logic is required, where a logic low turns the switch on. Compare against ADG512 for non-inverted logic or ADG513 for mixed logic configurations. Ensure the supply voltage aligns with the specified +3 V, +5 V, or ±5 V rails to maintain guaranteed on resistance and leakage specifications across the operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG511 belongs to the ADG511/ADG512/ADG513 family of precision 5 V/3 V quad SPST switches. These devices utilize advanced linear compatible CMOS technology to offer high performance with minimal power consumption. The family is designed for applications requiring wide analog signal ranges and precise switching capabilities in data acquisition and instrumentation environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG512 serves as a direct functional substitute if non-inverted digital control logic is preferred, sharing identical electrical characteristics and pinout. The ADG513 offers mixed logic control for two switches while maintaining similar performance metrics. Verify that any replacement maintains the required break-before-make timing and latch-up immunity for multiplexer applications.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ADG511 differ from the ADG512?

The ADG511 and ADG512 differ only in their digital control logic. The ADG511 switch turns on with a logic low input, whereas the ADG512 requires a logic high input to turn on.

What is the benefit of break-before-make switching?

Break-before-make operation ensures that one channel opens before another closes. This allows multiple outputs to be tied together for multiplexer applications without the risk of momentary shorting between channels.

What is trench isolation and why is it important?

Trench isolation removes the parasitic diodes found in standard junction isolation, preventing the formation of Silicon-Controlled Rectifier (SCR) circuits. This makes the device latch-up proof, protecting against destructive currents during overvoltage conditions.
