The LTC6269HDD-10#TRPBF is a low-voltage, low-power, single-supply instrumentation amplifier which is ideal for use in high-precision measurement applications. This device is highly power efficient and Rail-to-Rail operation at both the inputs and outputs helps to extend the dynamic range of the signal. This instrumentation amplifier includes a low-pass-filtered error amplifier to reduce offset and other errors due to nonzero gain margin and/or supply. The LTC6269HDD-10#TRPBF can be configured as an instrumentation amplifier, differential amplifier, buffer amplifier, voltage follower, or as two separate unity-gain buffers.

The LTC6269HDD-10#TRPBF is designed to operate from a single supply of +2.7V to +16V and has a low quiescent current consumption of 1.65µA making it a suitable device for low-power portable applications. Additionally, the LTC6269HDD-10#TRPBF features protected outputs, allowing the voltage of the output to be equal to the maxmimum allowed by the power supply. The maximum input and output differential voltage is 11V, making it perfect for high-voltage output amplifier applications.

The application field and working principle of the LTC6269HDD-10#TRPBF can best be illustrated by the example of a differential amplifier. In this example, the LTC6269HDD-10#TRPBF is used to amplify a small differential voltage between two input pins, without amplifying any common-mode signals which may be present. This is accomplished by a combination of the two buffers at the input and the differential stage at the output. The input buffers ensure that the common-mode signal present on the two inputs is not amplified by the differential stage, while the differential stage amplifies only the difference between the two inputs.

The LTC6269HDD-10#TRPBF has many other applications such as in a unity gain follower. In this application, the output of the LTC6269HDD-10#TRPBF is a mirror image of its input, effectively buffering the input signal and protecting the driving source from any loading effects. Additionally, the LTC6269HDD-10#TRPBF can be used in a voltage translator role, where it provides voltage shifting capabilities. This is useful for interfacing two circuits with different supply voltages, for example a 5V system and a 2.5V system.

The LTC6269HDD-10#TRPBF can also be used as an instrumentation amplifier. This is done by connecting the two input pins to two different signals, typically referred to as a “Sense” and “Inhibit” or “Reference” and “Signal” signals. The amplifier then takes the difference between the two signals and amplifies the difference. This is useful for measuring the small differences in signals, such as in pressure sensors and medical devices.

The LTC6269HDD-10#TRPBF is a low-voltage, low-power, single-supply instrumentation amplifier that is an ideal device for use in high-precision measurement applications. Its high power efficiency, low quiescent current consumption, and rail-to-rail operation make it a versatile choice for a variety of applications. In addition to differential amplification and unity-gain follower roles, it can be used as a voltage translator, instrumentation amplifier, and buffer amplifier. This device is helpful for interfaces with different supply voltages, measuring ultra-small signals, and buffering sensitive inputs. The LTC6269HDD-10#TRPBF is a robust, durable IC that can be used in a wide range of applications due to its many advantages.
