Overview
The AD7503JNZ is a monolithic CMOS 8-channel analog multiplexer that switches one of eight inputs to a common output based on three binary address lines and an inverted enable input. It features TTL/DTL and CMOS logic compatibility with a maximum on-resistance of 300 Ω, typical switching times of 0.8 µs for both turn-on and turn-off, and low power dissipation of 30 µW.
Feature Summary
- Inverted enable logic configuration
- Direct interface with TTL, DTL, and CMOS logic families
- Monolithic CMOS construction
Applications
- Data acquisition systems
- Process control applications
- Instrumentation signal routing
Procurement Notes
Verify the specific suffix 'JNZ' against official Analog Devices documentation, as standard commercial listings typically utilize 'KNZ'. Confirm current manufacturing status, as the AD7503 family has been marked obsolete in some distributor records. Ensure the component meets required environmental specifications for the intended application temperature range.
Selection Notes
Select the AD7503 over the AD7501 when an active-high enable signal is required, as the AD7503 utilizes inverted enable logic. Both devices share identical electrical characteristics and pinouts. Verify that the digital control inputs align with the system's logic voltage levels, as they are compatible with standard TTL and CMOS thresholds.
Part Context
The AD7503 belongs to the AD7501/AD7502/AD7503 family of analog multiplexers manufactured by Analog Devices. This series provides high-performance switching capabilities in various package options, including PDIP and surface-mount configurations. The device is designed for applications requiring reliable signal routing with minimal distortion and low power consumption.
Replacement Considerations
Public records indicate the ADG1408YRUZ as a similar replacement option. However, verify functional compatibility, as the ADG1408 is a different architecture. Since the AD7503 family is listed as obsolete, confirm availability and lead times through authorized channels or qualified alternative sources.
