Overview
The AD7506KQ is a monolithic CMOS analog multiplexer featuring sixteen independent channels. It operates with a nominal negative supply voltage of -15 V and supports a maximum negative supply of -18 V. The device provides a typical on-state resistance matching specification of 12 Ω, with a maximum on-state resistance of 300 Ω. It offers a nominal off-state isolation of 70 dB. The component is housed in a 28-pin ceramic DIP package.
Feature Summary
- Monolithic CMOS construction for high channel density
- Single-ended multiplexing architecture
- Ceramic dual in-line package for robustness
Applications
- Data acquisition systems requiring multi-channel signal routing
- Industrial process control instrumentation
- Test and measurement equipment signal switching
Procurement Notes
Verify compliance status as the component is marked non-compliant with current environmental directives such as RoHS. Confirm lead time requirements due to potential obsolescence or limited production runs. Ensure the specific KQ suffix matches the required ceramic packaging and temperature range specifications for the target application environment.
Selection Notes
Select this part when a high-density 16-channel single-ended switch is required within a legacy DIP form factor. Compare on-resistance stability and isolation performance against modern surface-mount alternatives if board space permits. Verify that the ±15 V supply rails align with the system power architecture before integration.
Part Context
This component belongs to the Analog Devices AD7506 family of CMOS analog multiplexers. The family includes variants with different pin counts and package types, such as 8-channel versions. The AD7506 specifically addresses applications needing multiple switched inputs in a compact, through-hole compatible footprint.
Replacement Considerations
Publicly confirmed substitutes include the MX7506KQ from Maxim Integrated, which shares similar functional characteristics and pinout compatibility. Designers should verify parameter margins, particularly regarding on-resistance and isolation, when cross-referencing with alternative manufacturers.
