TLC27L9CNSG4 is a precision unity-gain stable instrumentation amplifier from Texas Instruments that offers high accuracy and low bias current. It is an all-in-one analog circuit packaged into a single, 8-pin Dual In-Line (DIP) package, which makes it ideal for use in measurement and post-processing applications.

TLC27L9CNSG4 is designed to function as an adjustable-gain instrumentation amplifier, capable of amplifying small signals from sources such as thermocouples, load cells, strain gauges and other low-level signals up to the full-scale range of the amplifier. It provides an adjustable gain range from 0 dB to 45 dB, enabling an effective increase in signal-to-noise ratio output. The TLC27L9CNSG4 also offers a rail-to-rail output stage, allowing it to be used with high-voltage systems such as high-precision thermocouples and resistance bridge systems. Additionally, the amplifier features high common-mode rejection, low offset and excellent drift which results in increased accuracy and stability.

The linearity and accuracy of the TLC27L9CNSG4 is maintained even when operated over a wide temperature range. The amplifier\'s output is capable of handling up to -18 dBm of output signal power, capable of driving up to 20 input impedances, and can manage up to 2.5 pF of load capacitance.

TLC27L9CNSG4\'s working principle involves an adjustable gain instrumentation amplifier, which measures a differential input signal (Vin) and amplifies the signal with a gain of unity or more. The operational amplifier is the key component of the amplifier. It consists of four cascaded stages - two linear amps, a summing amplifier and an adjustable differential amplifier. First, two identical linear amplifiers consisting of transistors or operational amplifiers amplify the differential signal. The outputs of the two linear amplifiers are then “summed up” using a summing amplifier; the output of this stage is the amplified differential signal. Finally, an adjustable differential amplifier is used to adjust the gain of the amplifier. The gain is determined by the ratio between the resistors R1 and R2. The output of the adjustable differential amplifier is the amplified differential signal (Vout) with the gain set by R1/R2.

TLC27L9CNSG4 is ideal for applications such as 4-20 mA current loop transmitters, bridge sensor signal conditioning, adjustable gain instrumentation amplifiers, pressure sensors, laser diode output current monitoring, and other process control applications. It offers high accuracy and excellent long-term stability, even when exposed to high temperature environments. The TLC27L9CNSG4 also provides a rail-to-rail output stage for high-voltage drive capability, making it a good choice for thermocouples and other high-powered sensor systems. Additionally, its low-bias current makes it well suited for high-impedance voltage sensing applications. Its small 8-pin package allows for easy design-in, making it a great fit for many industrial, instrumentation and post-processing applications.
