LT1880

SOT-23, Rail-to-Rail Output,

Picoamp Input Current

Precision Op Amp

FEATURES

DESCRIPTIO

The LT^®1880 op amp brings high accuracy input perfor-

mance and rail-to-rail output swing to the SOT-23 pack-

age.Inputoffsetvoltageistrimmedtolessthan150µVand

the low drift maintains this accuracy over the operating

temperature range. Input bias current is an ultra low

900pA maximum.

■

Offset Voltage: 150µV Max

■

Input Bias Current: 900pA Max

■

Offset Voltage Drift: 1.2µV/°C Max

■

Rail-to-Rail Output Swing

■

Operates with Single or Split Supplies

■

Open-Loop Voltage Gain: 1 Million Min

■

1.2mA Supply Current

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

supplyand250mVofthepositivesupply,whichmakesthe

amplifier a good choice for low voltage single supply

operation.

■

Slew Rate: 0.4V/µs

■

Gain Bandwidth: 1.1MHz

■

Low Noise: 13nV/√Hz at 1kHz

Low Profile (1mm) ThinSOT^TMPackage

■

APPLICATIO S

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.

■

Thermocouple Amplifiers

■

Bridge Transducer Conditioners

■

Instrumentation Amplifiers

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