HA-2505
May 2003 FN2890.6
12MHz, High Input Impedance, Operational Amplifier
HA-2505 is an operational amplifier whose design is optimized to deliver excellent slew rate, bandwidth, and settling time specifications. The outstanding dynamic features of this internally compensated device are complemented with low offset voltage and offset current. This dielectrically isolated amplifier is ideally suited for applications such as data acquisition, RF, video, and pulse conditioning circuits. Slew rates of 30V/s and 330ns (0.1%) settling time make this device an excellent component in fast, accurate data acquisition and pulse amplification designs. 12MHz small signal bandwidth and 500kHz power bandwidth make this device well suited to RF and video applications. With 2mV typical offset voltage plus offset trim capability and 10nA offset current, HA-2505 is particularly useful in signal conditioning designs. The gain and offset voltage figures of the HA-2505 are optimized by internal component value changes while the similar design of the HA-2515 is maximized for slew rate. MIL-STD-883 product and data sheets are available upon request.
