NCS, NCSA. MHz, Wide Supply, Rail-to-Rail Output Operational Amplifier The NCS operational amplifier provides rail to rail output operation. The output can swing within 7 mv to the positive rail and mv to the negative rail. This rail to rail operation enables the user to make optimal use of the entire supply voltage range while taking advantage of. MHz bandwidth. The NCS can operate on supply voltage as low as. V over the temperature range of C to C. The high bandwidth provides a slew rate of. V/ s while only consuming a typical 9 A of quiescent current. Likewise the NCS can run on a supply voltage as high as 6 V making it ideal for a broad range of battery operated applications. Since this is a CMOS device it has high input impedance and low bias currents making it ideal for interfacing to a wide variety of signal sensors. In addition it comes in either a small SC 88A or UDFN package allowing for use in high density PCB s. Features Rail To Rail Output Wide Bandwidth:. MHz High Slew Rate:. V/ s Wide Power Supply Range:.

If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.. Continuous short circuit operation to ground at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of C. Output currents in excess of ma over long term may adversely affect reliability. Shorting output to either V+ or V will adversely affect reliability. DC ELECTRICAL CHARACTERISTICS (V DD =. V,.
