LT1885 Description

The 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 400pA 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 40mV of the negative supply and 220mV 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 1mA per amplifier give superior response and settling time performance in a low power precision amplifier.

The quad LT1885 is also in the standard pinout 14-pin SO package.
