Overview
The AD7503JN 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 typical power dissipation of 30 µW. The device offers a maximum on-resistance (RON) of 300 Ω and a channel-to-channel matching (ΔRON) of 12 Ω. Leakage current (IS(off)) is typically 0.2 nA, while supply current (IDD) reaches 800 µA max with all digital inputs high.
Feature Summary
- Inverted enable logic distinguishes the AD7503 from the AD7501
- Direct interface with DTL, TTL, and CMOS logic families
- Low power consumption suitable for battery-operated systems
Applications
- Data acquisition systems requiring signal routing
- Process control instrumentation
- Industrial automation controllers
- Medical equipment signal conditioning
Procurement Notes
Verify component status as obsolete or end-of-life through official Analog Devices channels. Confirm availability of alternative packages such as CERDIP or LCC if PDIP is unavailable. Ensure ESD precautions are strictly followed during handling due to CMOS sensitivity. Validate pinout compatibility with existing PCB layouts before integration.
Selection Notes
Select the AD7503 when inverted enable logic is required compared to the standard AD7501. Consider the AD7502 for dual 4-channel applications within the same package footprint. Evaluate RON variations across temperature ranges for precision requirements. Verify voltage supply limits against absolute maximum ratings to prevent device damage.
Part Context
The AD7503 belongs to the AD7501/AD7502/AD7503 family of monolithic CMOS analog multiplexers manufactured by Analog Devices. These devices provide reliable switching for analog signals in various industrial and commercial environments. The family shares similar electrical characteristics but differs in channel configuration and enable logic polarity.
Replacement Considerations
Public documentation identifies the ADG1408YRUZ as a potential substitute. Verify functional equivalence regarding channel count, package type, and electrical specifications. Confirm that the replacement supports the required inverted enable logic or adjust circuit design accordingly.
