Avnet Memec, the highly specialised semiconductor distributor of Avnet Electronics Marketing EMEA, adds DS8500 from Maxim Integrated Products to its portfolio. The DS8500 is a single-chip, HART-compliant modem IC that enables the smallest solution size for modulating and demodulating 1.2kHz/2.2kHz FSK signals.

This device integrates an ADC and state machine to implement the digital filter required to eliminate noise from the HART signal. The built-in digital filter minimizes the number of external components while ensuring reliable signal detection in noisy industrial environments. A simple, single-pole, lowpass/highpass RC filter is all that is required externally. Additionally, the DS8500 features a low, 285μA (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°C to +85°C extended temperature range. It is available in a lead-free, 5mm x 5mm x 0.8mm, 20-pin TQFN package.
