LT1884/LT1885 Dual/Quad Rail-to-Rail Output, Picoamp Input Precision Op Amps Features s s s s s s s s s DESCRIPTIO Offset Voltage: 50µV Max (LT1884A) Input Bias Current: 400p A Max (LT1884A) Offset Voltage Drift: 0.8µV/°C Max Rail-to-Rail Output Swing Operates with Single or Split Supplies Open-Loop Voltage Gain: 1 Million Min 1m A Maximum Supply Current Per Amplifier Slew Rate: 1V/µs Standard Pinouts The LT®1884/LT1885 op amps bring high accuracy input performance to amplifiers with rail-to-rail output swing while providing faster response than other precision amplifiers. Input offset voltage is trimmed to less than 50µV and the low drift maintains this accuracy over the operating temperature range. Input bias currents are an ultralow 400p A maximum. The amplifiers work on any total power supply voltage between 2.7V and 36V (fully specified from 5V to ± 15V). Output voltage swings to within 40m V of the negative supply and 220m V of the positive supply make these amplifiers good choices for low voltage single supply operation. Slew rates of 1V/µs with a supply current of less than 1m A 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
