ADG511ABR-REEL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG511ABR-REEL7 is a trench-isolated, latch-up-proof quad SPST analog switch in a 16-lead SOIC package. It operates from single +3 V to +5.5 V or dual ±4.5 V to ±5.5 V supplies. Key electrical parameters include a maximum on-resistance of 50 Ω at ±4.5 V and 75 Ω at +5 V single supply. Leakage currents are typically ±25 pA with a maximum of ±2.5 nA at ±5.5 V. Switching times reach 375 ns (on) and 150 ns (off) under dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific 'ABR' suffix indicates trench-isolated construction compared to standard variants. Confirm the reel packaging matches the REEL7 designation. Ensure the component meets industrial temperature range requirements (-40°C to +85°C). Check for RoHS compliance status as manufacturing processes may vary by production batch.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this device when latch-up immunity is critical for system robustness. The ADG511 offers inverted logic control relative to the ADG512. Consider the ADG513 if mixed logic polarity is required within the same package. Evaluate on-resistance tolerance against signal integrity needs, as RON varies with supply voltage and temperature.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG511/ADG512/ADG513 family of precision CMOS analog switches. The ADG511 variant features active-low control inputs. The 'ABR' designation specifically denotes the trench-isolated version housed in a 16-lead Small Outline Integrated Circuit (SOIC) package, distinguishing it from junction-isolated counterparts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Standard ADG511BR parts lack trench isolation and may be susceptible to latch-up under overvoltage conditions. The ADG512BR serves as a functional substitute only if inverted logic control is acceptable. Verify pinout compatibility and thermal characteristics when substituting with non-trench isolated versions.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the primary difference between the ADG511ABR and the standard ADG511BR?

The ADG511ABR utilizes trench isolation technology, making it latch-up proof, whereas the standard ADG511BR uses junction isolation which can be susceptible to latch-up under certain overvoltage conditions.

How does the break-before-make feature benefit multiplexer designs?

It ensures that one channel disconnects before another connects, preventing momentary short circuits between multiple outputs when they are tied together in multiplexer configurations.

Is the ADG511 compatible with 3.3 V logic levels?

Yes, the device is TTL/CMOS compatible. With a +3.3 V supply, the input high voltage minimum is 2.4 V and the input low voltage maximum is 0.8 V, allowing direct interface with standard logic families.
