The Analog Devices DS1620S-001 is a digital thermometer and thermostat, combining temperature measurement with a programmable thermostat output in a single monolithic device. It is designed for applications requiring accurate temperature monitoring and threshold-based control — think thermal management in industrial equipment, telecom enclosures, or HVAC system sub-assemblies where a direct digital readout and a setpoint-driven output replace a discrete thermistor-and-comparator chain.
The DS1620S-001 is marked RoHS non-compliant, meaning it contains lead or other restricted substances above the RoHS exemption thresholds. This is a firm fit constraint: designs targeting EU RoHS, China RoHS, or similar regulations cannot use this part without an exemption claim. For military, aerospace, or certain industrial applications that are RoHS-exempt or not regulated, this is not a blocker. Procurement should verify the end-equipment regulatory scope before committing the line.
This means the manufacturer continues to produce the part, and there is no announced end-of-life (EOL) or last-time-buy window. New designs can proceed with the part without near-term obsolescence risk.
