What this current-sense amplifier does and where it fits
The MAX4173HEUT+T from Analog Devices is a single-channel current-sense amplifier in a SOT-23-6 package. It measures current by amplifying the voltage drop across an external sense resistor, with a -3 dB bandwidth of 1.2 MHz.
Package and mounting — what the SOT-23-6 means for assembly
The SOT-23-6 (also called SOT-6) is a surface-mount package. It reflows on standard lead-free profiles and is compatible with both paste-in-hole and conventional SMT lines. The cut-tape option (CT) is handy for prototype builds; the tape-and-reel (TR) is the production volume format.
