Malvern, Pa. Two new families of precision thin-film resistor networks from Vishay Intertechnology Inc. extend the ratio tolerance to a new industry-low of 0.01% in SOT-23 and 8-pin SOIC packages. The MPM and ORN matched-pair and quad resistor networks offer designers an alternative to technologies such as wirewound and hermetic packaging that was previously required to maintain a low tolerance. These devices are designed for instrumentation amplifiers, precision voltage dividers and bridge network circuitry.
New devices in the MPM series of thin-film resistor dividers feature temperature coefficient ratio tracking (TCR) of ±2 ppm/°C and provide high stability for all surface-mount applications. Standard divider ratio options range from 1:1 to 100:1. Custom non-standard ratios are available on request.
Built with highly stable thin-film and packaged in a rugged, molded 8-pin SOIC, the newest additions to the ORN family of dual-in-line resistor networks feature four isolated resistors with standard 50-mil pitch lead spacing. With close TCR tracking of ±5 ppm/°C and a tight ratio tolerance down to 0.01%, the ORN devices are suitable for unity gain operational amplifier circuitry. Nine standard resistance values are available from 500 Ω to 100 KΩ.
