THS3201DGK Application Field and Working Principle

The TI (Texas Instruments) THS3201DGK is a high-performance, low-noise, low-drift, low-power instrumentation amplifier. It belongs in the subcategory of linear amplifiers, specifically instrumentation, op amps, and buffer amps. It is suitable for applications such as medical instrumentation, industrial sensors, high-precision data acquisition, and audio measurement and especially excels when used in electrocardiography (ECG) and electrophysiology (EP) setups.

Features and Benefits

The THS3201DGK offers a number of features that make it a versatile and robust device for instrumentation. Its high-impedance, amplified inputs prevent input shorts and limit supply current draw. The amplifier also features a low input noise of 0.9 nV/√Hz and a wide operating temperature range from -40°C to 125°C. In addition to its excellent performance, the THS3201DGK is also power and cost efficient, requiring only 3 mA of supply current.

Working Principle

The THS3201DGK amplifies signals by utilizing a pair of low-noise differential amplifiers. These amplifiers then generate an output that is proportional to the input differential voltage. To achieve a high gain, the instrumentation amplifier utilizes a three-stage process. First, the input signals pass through the differential amplifiers and are then added together. This sum is then sent to a unity gain buffer. Finally, the output gain is increased through gain-setting resistors. This process allows for a high output gain with minimal noise, drift, and power.

Additional Benefits

The THS3201DGK also boasts an internal filter that allows for a flat frequency response. This makes it ideal for precision applications, as it can filter out unwanted frequency responses and interference. In addition, the amplifier has a built-in offset voltage adjuster which allows the user to fine-tune the output as desired. Furthermore, the THS3201DGK is designed to be low-power and low-noise, making it ideal for applications that require prolonged run times or precise measurements.
