The LT1114IS#TRPBF is a low power, single supply instrumentation amplifier. This amplifier is designed to operate from a single +5V power supply, and provides up to 1MHz of gain bandwidth and a 33nV/√Hz input noise figure. The amplifier\'s output features rail-to-rail, high current conditioning and can be configured as a low pass filter, for driving loads such as low power transistors, low current, high voltage analog switches and other active loads. The device also features an on-chip output protection circuit and built in thermal shutdown protection.

The LT1114IS#TRPBF can provide a wide range of application fields including MEMS, automotive instrumentation, HIL (hardware in the loop) testing and medical instrumentation. The amplifier is also suitable for motor control applications and other low level signal conditioning tasks. Its low noise and power requirement makes it an ideal choice for mobile, battery powered, and portable applications.

The LT1114IS#TRPBF’s working principle is based on the use of an input differential pair and a pair of rail-to-rail outputs. The differential pair is designed to have high common-mode rejection, which isolates the input signals from the output stage, allowing better use of available dynamic range. The output stage features rail-to-rail operation on both the positive and negative side of the output, ensuring that the device can drive both high and low impedance loads. The output is also adjustable, allowing for simple voltage scaling of output signals.

The LT1114IS#TRPBF features a slew rate selectable from 500kHz to 5MHz and a gain up to 100dB. It also includes an on-chip output protection circuit, allowing the amplifier to protect against shorts and high energy transients. Other features of the LT1114IS#TRPBF include an integrated output current limiting circuit, temperature stability and hysteresis protection.

In summary, the LT1114IS#TRPBF is a single supply instrumentation amplifier featuring a low power requirement, a wide output dynamic range and a fast signal response. Due to its low noise and power requirements, it is perfect for mobile, battery powered and portable applications. Additionally, the amplifier includes an integrated output protection circuit, ensuring its safety against over current conditions.
