Low Power Instrument Amplifier, 125uV, 800kHz, 1.35V to 18V - 

The INA118P is a precision low power Instrumentation Amplifier offers excellent accuracy. Its versatile 3-op amp design and small size make it ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (70kHz at G=100). A single external resistor sets any gain from 1 to 10000. Internal input protection can withstand up to ±40V without damage. The INA118 is laser trimmed for very low offset voltage (50µV), drift (0.5µV/°C) and high common-mode rejection (110dB at G=1000). It operates with power supplies as low as ±1.35V and quiescent current is only 350µA ideal for battery operated systems.
