The OPA828 JFET is the next generation OPA627 and OPA827 operational amplifier (op amp), combining high speed with high DC precision and AC performance. This op amp supplies low-offset voltage (50 µV), low-drift over temperature (0.45 µV/°C typical), low bias current (1 pA typical), and low noise (4 nV/√Hz typical) with only 60-nVRMS 0.1- to 10-Hz noise. The OPA828 operates over a wide supply-voltage range, ±4 V to ±18 V on a supply current (5.5 mA/channel typical).
AC characteristics, including a 45-MHz gain bandwidth product (GBW), a slew rate of 150 V/µs, and precision dc characteristics, make the OPA828 an excellent choice for a variety of systems. These include high-speed and high-resolution data-acquisition systems, such as 16-bit to 18-bit mixed signal systems, transimpedance (I/V-conversion) amplifiers, filters, precision ±10-V front ends, and high-impedance sensor-interface applications.
The OPA828 is available in the industry-standard 8-pin SOIC surface-mount package and is specified from –40°C to +125°C.
