99 FEATURES ? Linear voltage output vs %RH ? Laser trimmed interchangeability ? Low power design ? High accuracy ? Fast response time ? Stable, low drift performance ? Chemically resistant TYPICAL APPLICATIONS ? Refrigeration ? Drying ? Meteorology ? Battery-powered systems ? OEM assemblies GENERAL INFORMATION The HIH-3605 monolithic IC (Integrated Circuit) humidity sensor is designed spe- cifically for high volume OEM (Original Equipment Manufacturer) users. Direct input to a controller or other device is made possible by this sensor's linear volt- age output. With a typical current draw of only

200 ?A, the HIH-3605 is ideally suit- ed for low drain, battery powered sys- tems. The HIH-3605 delivers instrumentation quality RH sensing performance in a low cost, solderable SIP (Single In-line Pack- age). Available in two lead spacing con- figurations, the RH sensor is a laser trimmed thermoset polymer capacitive sensing element with on-chip integrated signal conditioning.

MOUNTING DIMENSIONS (for reference only) HIH-3605-A HIH-3605-B NIST CALIBRATION HIH-3605 sensors may be ordered with a NIST calibration and sensor specific data printout. Append ''?CP'' to the model number to order. RH SENSOR CONSTRUCTION Sensor construction consists of a planar capacitor with a sec- ond polymer layer to protect against dirt, dust, oils and other hazards. CAUTION PRODUCT DAMAGE The inherent design of this component causes it to be sensitive to electrostatic discharge (ESD). To prevent ESD-induced damage and/or degradation, take normal ESD precautions when handling this product. Humidity Humidity Sensors HIH Series Relative Humidity
