Analog Devices / Maxim Integrated MAX49921 Evaluation Kit (MAX49921EVKIT)

Analog Devices MAX49921 Evaluation Kit (MAX49921EVKIT) provides a reference design based on the MAX49921 Current-Sense Amplifier (CSA). The MAX49921 is an AEC-Q100 qualified unidirectional current-sense amplifier optimized for current monitoring of inductive loads, such as DC motors and solenoids, where common-mode voltages can become negative due to inductive kickback, reverse-battery conditions, or transient events.

The Analog Devices MAX49921 Evaluation Kit (MAX49921EVKIT) features a pre-mounted MAX49921 in a 2mm x 3mm, side-wettable TDFN8 package with a gain of 50V/V. Multiple test points enable easy access to all key pin signals.
