AD7501JN

The Analog Devices AD7501JN is a monolithic CMOS 8-channel analog multiplexer. It selects one of eight inputs and switches it to a common output based on three binary address lines and an enable input. This device is suitable for applications requiring efficient analog signal routing.

Key electrical characteristics include a typical on-state resistance of 170 Ohms, with a maximum of 300 Ohms. The on-state resistance variation versus supply voltage is typically 20%, and versus temperature is typically 0.5%/°C. Channel-to-channel resistance matching is typically 4%, with a variation versus temperature of ±0.01%/°C. Leakage currents are minimal, with source and drain off-state leakage typically 0.2 nA and output off-state leakage typically 1 nA.

Digital inputs are compatible with TTL/DTL and CMOS logic levels, with a maximum input low voltage of 0.8V and a minimum input high voltage of 2.4V. Input capacitance is typically 3 pF. Switching performance is characterized by a typical turn-on time of 0.8 µs and a typical turn-off time of 0.8 µs.

The AD7501JN is available in a 16-lead DIP and a 20-terminal surface mount package. The surface mount package is a TQFN type, suitable for automated assembly processes.
