**ADG507AKRZ: A Comprehensive Technical Overview of the Analog Multiplexer IC**

The **ADG507AKRZ** from Analog Devices represents a high-performance, monolithic, CMOS analog multiplexer designed to handle a wide array of signal switching applications. This IC is a member of a family known for its precision and reliability, making it a cornerstone component in systems where signal integrity and accuracy are paramount. It functions as a **single-pole, eight-throw (SP8T)** switch, meaning it can route one common input to any one of eight separate output channels, or vice versa, under digital control.

Constructed on an advanced **CMOS process**, the ADG507AKRZ offers exceptionally low power consumption, making it suitable for both battery-powered portable equipment and sophisticated fixed installations. A key feature of this multiplexer is its **break-before-make switching action**, which prevents momentary shorting between channels during transition, thereby protecting sensitive source and destination circuitry. The device is designed to handle **bipolar analog signals** within its supply voltage range, which typically spans from ±12 V to ±15 V for dual supplies, supporting a wide analog input range.

The on-resistance (**R_ON**) of the ADG507AKRZ is a critical parameter, typically measuring a very low 200 ohms with excellent flatness across the specified signal range. This low and consistent on-resistance ensures minimal signal attenuation and distortion, which is vital for maintaining accuracy in precision measurement systems. Furthermore, the device boasts **very low leakage currents**, in the nanoampere range, which is essential for applications involving high-impedance sources, such as in electrochemical sensor interfaces or sample-and-hold circuits.

Digital control is achieved through a **3-bit binary address line (A0, A1, A2)** and an enable pin. The TTL/CMOS-compatible logic inputs simplify interfacing with modern microcontrollers, FPGAs, and digital signal processors. The robust design includes **latch-up immunity**, a crucial safeguard against catastrophic failure caused by voltage surges beyond the supply rails.

Primary applications for the ADG507AKRZ are found in data acquisition systems (DAQs), automated test equipment (ATE), medical instrumentation, audio and video routing, and communication systems. Its ability to accurately switch and multiplex analog signals without significant degradation makes it an indispensable component for engineers designing high-performance electronic systems.
