SOT-23, Rail-to-Rail Output, Picoamp Input Current Precision Op Amp

The LT1880 op amp brings high accuracy input performance and rail-to-rail output swing to the SOT-23 package. Input offset voltage is trimmed to less than 150μV and the low drift maintains this accuracy over the operating temperature range. Input bias current is an ultralow 900pA maximum.

The amplifier works on any total power supply voltage between 2.7V and 36V (fully specified from 5V to ±15V). Output voltage swings to within 55mV of the negative supply and 250mV of the positive supply, which makes the amplifier a good choice for low voltage single supply operation.

Slew rates of 0.4V/μs with a supply current of 1.2mA give superior response and settling time performance in a low power precision amplifier.

The LT1880 is available in a 5-lead SOT-23 package.
