Product Overview
LT®1991 combines a precision operational amplifier with eight precision resistors to form a one-chip solution for accurately amplifying voltages. Gains from -13 to 14 with a gain accuracy of 0.04% can be achieved using no external components. The device is particularly well suited for use as a difference amplifier, where the excellent resistor matching results in a common mode rejection ratio of greater than 75dB. The resistors have excellent matching, 0.04% over temperature for the 450K resistors. The matching temperature coefficient is guaranteed less than 3ppm/°C. The resistors are extremely linear with voltage, resulting in a gain nonlinearity of less than 10ppm. Typical applications are handheld instrumentation, medical instrumentation, strain gauge amplifiers, differential to single-ended conversion.
- Pin configurable as a difference amplifier, inverting and noninverting amplifier
- Rail-to-rail output
- Gain nonlinearity is 10ppm max (VS=±15V; VOUT=±10V; RL=10K, -40°C to 85°C)
- Gain drift vs temperature is 3ppm/°C max (VS=±15V; VOUT=±10V; RL=10K)
- Op-amp offset voltage drift is 1µV/°C (VS=±15V; VOUT=±10V; RL=10K, -40°C to 85°C)
- Op-amp input noise voltage is 0.35µVP-P typ (0.01Hz to 1Hz, VS=±15V; VOUT=±10V, -40°C to 85°C)
- Op-amp gain bandwidth product is 560KHz typ (f=10KHz)
- 10-lead plastic MSOP package
- Temperature rating range from -40°C to 85°C
