What are the key features of AD7501KNZ?
- 8-channel single-ended analog multiplexer with ±15 V dual supply operation for rail-to-rail analog signal switching across a wide ±10 V signal range
- Low on-resistance CMOS switch design enables precise analog signal routing with minimal signal degradation in 16-pin DIP through-hole package
- Binary-coded 3-bit address inputs select 1-of-8 analog channels, simplifying microcontroller interface for multi-channel data acquisition systems
What is AD7501KNZ used for?
The AD7501KNZ is used in data acquisition systems, instrumentation, and industrial process control equipment where multiple analog sensor signals must be sequentially routed to a single ADC input. Its ±15 V dual-supply operation makes it compatible with precision op-amp signal conditioning chains, enabling multi-channel temperature, pressure, or voltage measurement front-ends in laboratory instruments and programmable logic controllers.

Frequently Asked Questions
How many analog input channels does the AD7501KNZ support and how are they addressed?
The AD7501KNZ supports 8 single-ended analog input channels selected via a 3-bit binary address on pins A0, A1, and A2, plus an active-low enable input. All 8 channels share a single common output pin, enabling a microcontroller to multiplex 8 analog signals to one ADC using only 3 digital address lines, reducing GPIO consumption in multi-channel measurement systems.
What supply voltage does the AD7501KNZ require and what analog signal range can it pass?
The AD7501KNZ operates from dual ±15 V supplies with a nominal negative supply of -15 V and positive supply of +15 V. This dual-supply configuration allows the device to pass analog signals spanning ±10 V, making it compatible with standard instrumentation amplifier outputs and precision ADC input ranges in industrial measurement systems without signal clipping or level shifting.
What is the typical on-resistance of the AD7501KNZ and how does it affect measurement accuracy?
The AD7501KNZ CMOS switch has a typical on-resistance of approximately 150 ohms to 300 ohms per channel. When driving high-impedance ADC inputs, this on-resistance introduces negligible voltage error because input current is near zero. However, for applications with source impedances below 1 kohm, the on-resistance forms a divider that can introduce a gain error of several tenths of a percent, requiring a buffer amplifier between the mux output and ADC.
Is the AD7501KNZ still in production and what modern alternatives exist if it is end-of-life?
The AD7501KNZ is a legacy device from Analog Devices' classic CMOS mux family and has a YTEOL rating of 0, indicating limited remaining production life. Modern pin-compatible or functionally equivalent alternatives include the ADG508A or MAX308 8-channel multiplexers, which offer lower on-resistance below 100 ohms, faster switching times under 200 ns, and wider temperature ranges down to -40°C versus the AD7501's 0°C to 70°C commercial grade.
For a portable multi-channel sensor logger design, would AD7501KNZ be appropriate or should an engineer use a single-supply mux?
The AD7501KNZ requires dual ±15 V supplies, consuming significant power in a portable design and requiring two voltage rails. For battery-powered sensor loggers operating from a single 3.3 V or 5 V supply, single-supply multiplexers such as the ADG708 (3 V to 5.5 V, 8 channels, 4 ohm on-resistance) are more appropriate. The AD7501KNZ is best retained in existing benchtop instrument designs already using ±15 V power planes.
