LT5400 Quad Matched Resistor Network Fea T Descrip T n Excellent Matching The LT 5400 is a quad resistor network with excellent n A-Grade: 0.01% Matching matching specifications over the entire temperature range. n B-Grade: 0.025% Matching Matching is also specified when the LT5400 is configured n 0.2ppm/C Matching Temperature Drift in a difference amplifier. This enhanced matching specifica- n 75V Operating Voltage (80V Abs Max) tion guarantees CMRR performance to be up to 2 better n 8ppm/C Absolute Resistor Value Temperature Drift than independently matched resistors. n Long-Term Stability: <2ppm at 2000 Hrs All four resistors can be accessed and biased independently, n 55C to 150C Operating Temperature making the LT5400 a convenient and versatile choice for n 8-Lead MSOP Package any application that can benefit from matched resistors. These resistor networks provide precise ratiometric stability a T required in highly accurate difference amplifiers, voltage references and bridge circuits. n Difference Amplifier n Reference Divider The LT5400 is available in a space-saving 8-pin MSOP n Precision Summing /Subtracting package, and is specified over the temperature range of 55C to 150C.
