Triple-function analog block for smart-card interfaces
The Maxim Integrated MAX9004EUB+ packs an amplifier, a comparator, and a voltage reference into a single 10-pin 10-uMAX/uSOP package. It is explicitly designed for Smart Card applications, where these three analog functions are needed in a small footprint — the amplifier handles signal conditioning from the card's I/O line, the comparator monitors card-detect or overcurrent events, and the reference provides a stable threshold.
The device is supplied in a 10-TFSOP or 10-MSOP package (0.118" wide, 3.00 mm body width), with the supplier device package listed as 10-uMAX/uSOP. Mounting is surface mount, and the part ships in Tube form. The small footprint suits space-constrained smart-card reader modules or payment terminals.
