OPA2141AIDR

10MHz单电源低噪声双路JFET精密放大器

DESCRIPON

The OPA141, OPA2141, and OPA4141 amplifier family is a series of low-power JFET input amplifiers that feature good drift and low input bias current. The rail-to-rail output swing and input range that includes V– allow designers to take advantage of the low-noise characteristics of JFET amplifiers while also interfacing to modern, single-supply, precision analog-to-digital converters ADCs and digital-to-analog converters DACs.
