LT5400 Quad Matched Resistor Network
FeaTures DescripTion
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 –55°C to 150°C 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
