The INA103KU/1KE4 from Texas Instruments is a high performance, low power, precision instrumentation amplifier.

• Gain Range: 1 to 1000
• Design: Three-op-amp design, laser-trimmed resistors for high accuracy, and an on-chip resistor network for setting gain.
• Supply Range: +/-2.25V to +/-18V
• Offset Voltage: 50µV (max) over temperature
• Noise: 8nV/√Hz
• Total Harmonic Distortion: 0.0006% @ G = 100
• Temperature Range: -40 to +85°C
• Quiescent Current: 1.8mA
• Power-Down Feature: Reduces current consumption to less than 1µA
