MAX9634 Evaluation Kit
Evaluates: MAX9634
General Description
The MAX9634 evaluation kit (EV kit) provides a proven
design to evaluate the MAX9634 high-side current-sense
amplifier, which offers precision accuracy specifications
of V
OS
less than 250µV (max) and gain error less than
0.5% (max). This EV kit demonstrates the MAX9634 in
a tiny 1mm x 1mm x 0.6mm, 4-bump UCSP™ package.
The MAX9634 is also available in a 5-pin SOT23, but that
package is not compatible with this EV kit.
The EV kit PCB comes with a MAX9634FERS+ installed,
which is the 50V/V gain version. Contact the factory for
free samples of the pin-compatible MAX9634TERS+,
MAX9634HERS+, and MAX9634WERS+, which are
25V/V, 100V/V, and 200V/V gain versions, respectively.
