OPA2828 RRO JFET Op Amp

Texas Instruments' op amp features the extremely advanced high-voltage SiGe complementary, JFET-bipolar process technology

Image of Texas Instruments' OPA2828 RRO JFET Op AmpTexas Instruments' OPA2828 dual JFET input op amp is the next generation of the OPA627 and OPA827, combining high speed, high DC precision, and AC performance. These op amps supply low offset voltage, low drift overtemperature, low bias current, and low noise of 60 nVRMS (0.1 Hz to 10 Hz noise range). The op amps operate over a wide supply-voltage range of ±4 V to ±18 V and a supply current of 5.5 mA per channel (typical).

The AC characteristics include a 45 MHz gain bandwidth (GBW), slew rate of 150 V/μs, and precision DC characteristics making the device an excellent choice for a variety of systems. These include high-speed and high-resolution data acquisition (DAQ) systems such as 16-bit to 18-bit mixed signal systems, transimpedance (I/V-conversion) amps, filters, precision ±10 V front-ends, and high-impedance sensor-interface applications. The OPA2828 is available in a thermally-enhanced 8-pin HVSSOP PowerPAD™ integrated circuit package.
