It delivers a ground-referenced output proportional to the sensed current, simplifying interface to an ADC or comparator. The part operates from a 3.6 V to 24 V supply span, covering common industrial and automotive rails, and draws only 100 µA supply current — useful for always-on monitoring without loading the rail. With a 100 kHz bandwidth, it tracks switching regulator currents and load transients cleanly. The -40°C to 125°C temperature range suits under-hood and factory-floor environments. ## Package and mounting Housed in an 8-pin 3.00 mm × 3.00 mm uMAX/uSOP package (MSOP-8 compatible), the MAX4070AUA+ is a surface-mount device. The small footprint saves board area in dense designs. The tube shipping medium is typical for prototype and low-volume builds; for production reels, check the alternate ordering suffix. ## Lifecycle and sourcing The MAX4070AUA+ carries an Active product status with ROHS3 compliance. No end-of-life notification or last-time-buy window is currently in effect, so it remains suitable for both new designs and ongoing production.","metaTitle":"MAX4070AUA+ Current Sense Amplifier, 100 kHz, 8-uMAX/uSOP","metaDescription":"MAX4070AUA+ current sense amplifier from Analog Devices. 3.6 V to 24 V supply, 100 kHz bandwidth, -40°C to 125°C.
