LT1996 - Precision, 100μA Gain Selectable Amplifier

LT1996 - Precision, 100μA Gain Selectable Amplifier - Linear Technology（凌力尔特）

The LT1996 combines a precision operational amplifier with eight precision resistors to form a one-chip solution for accurately amplifying voltages. Gains from -117 to 118 with a gain accuracy of 0.05% can be achieved without any 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 80dB.

The amplifier features a 50µV maximum input offset voltage and a gain bandwidth product of 560kHz. The device operates from any supply voltage from 2.7V to 36V and draws only 100µA supply current on a 5V supply. The output swings to within 40mV of either supply rail.

The internal resistors have excellent matching characteristics; variation is 0.05% over temperature with a guaranteed matching temperature coefficent of less than 3ppm/°C. The resistors are also extremely stable over voltage, exhibiting a nonlinearity of less than 10ppm.

The LT1996 is fully specified at 5V and ±15V supplies and from -40°C to 85°C. The device is available in space saving 10-lead MSOP and DFN packages. For an amplifier with selectable gains from -13 to 14, see the LT1991 data sheet.
