... Slew rates of 1V/ s with a supply current of less than 1mA per amplifier give superior response and settling time performance in a low power precision amplifier. The dual LT1884 is available with standard pinouts in 8-pin SO and PDIP packages. The quad LT1885 is also in the standard pinout 14-pin SO package. ...
