Texas Instruments OPAx828 JFET-Input Operational Amplifier
Texas Instruments OPAx828 JFET-Input Operational Amplifier 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, low drift over temperature, low bias current, and low noise with only 60nVRMS 0.1 to 10Hz noise. The OPA828 operates over a wide supply-voltage range, ±4V to ±18V, on a supply current of 5.5mA/channel (typical).
AC characteristics, including a 45MHz gain bandwidth product (GBW), a slew rate of 150V/µs, and precision dc characteristics, make the Texas Instruments OPAx828 an excellent choice for various systems. These include high-speed and high-resolution data-acquisition systems, such as 16-bit to 18-bit mixed-signal systems. It also includes transimpedance (I/V-conversion) amplifiers, filters, precision ±10V front ends, and high-impedance sensor-interface applications.
