Linear Technology has introduced the LT5400 family of resistors that is designed for signal conditioning applications in difference amplifiers, precision dividers, references and bridge circuits. Each resistor has guaranteed matching of 0.01% from -40 to 85°C, and 0.0125% from -40 to 125°C. The resistor matching is enhanced with "matching for CMRR (common-mode rejection ratio)", a metric that guarantees CMRR performance when configured in a difference amplifier circuit.
The resistors' LT5400 mini small outline package minimises thermal gradients, and ensures consistent conditions over time and temperature for all four resistors. The resistors are based on silicon fabrication and assembly, and are insensitive to shock, vibration, humidity and temperature extremes. The resistors also have a high temperature option that is fully specified from -55 to 150°C. They are suitable for instrumentation and test equipment in heavy industrial, military and automotive environments.
