OPA828 (ACTIVE)

36 V, High-precision, low-noise, low bias current, JFET-input 45 MHz Op Amp

 

Description

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.
