HART Modem IC Minimizes System Size and Power Consumption

A simple, single-pole, lowpass/highpass RC filter is all that is required externally. Additionally, the DS8500 features a low, 285microamp (max) active-mode current for applications in which low power consumption is critical. Packaged in a space-saving TQFN, the DS8500 is ideal for space-constrained, 4-20mA current-loop applications.

The DS8500 operates from 2.7V to 3.6V, and is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. It is available in a lead-free, 5mm x 5mm x 0.8mm, 20-pin TQFN package. Pricing starts at $4.10 (1000-up, FOB USA).
