Two new precision thin film resistor networks from Vishay Intertechnology extend the ratio tolerance of the company's MPM and ORN matched-pair and quad resistor networks to a new industry low of just 0,01% in standard SOT-23 and 8-pin SOIC packages.
Intended for use in instrumentation amplifiers, precision voltage dividers, and bridge network circuitry, the devices provide an alternative to technologies such as wirewound or hermetic packaging previously required to maintain such a low tolerance.
In addition to being precision-matched, the new MPM thin film resistor dividers feature temperature coefficient ratio tracking (TCR) of ±2 ppm/°C and provide exceptional stability for all surface-mount applications. Standard divider ratio options range from 1:1 to 100:1.
Built with highly stable thin film and packaged in a rugged, moulded 8-pin SOIC construction, these 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 tight ratio tolerance down to 0,01%, ORN devices are ideally suited for unity gain op-amp circuitry. The nine standard resistance values range from 500 Ω to 100 kΩ.
As replacements for discrete chip resistors, the MPM and ORN series devices combine space savings and superior performance, with resistive elements integrated within a single package onto a common substrate and resulting in near-identical conditions over time and temperature for each element.
