The TS464CPT is a high-performance, low-power operational amplifier with its performance optimized for current sensing applications. It has a wide range of applications from measuring motor current to providing precision current-sensing feedback for sophisticated motor control systems. The TS464CPT has excellent linearity, low temperature drift, and wide bandwidth.

The TS464CPT can be classified as a linear amplifier, instrumentation amplifier, operational amplifier, buffer amplifier, or current-sensing amplifier. It is a low-power amplifier, capable of providing up to 12V of output swing with a maximum quiescent current of 45uA.

The TS464CPT is an operational amplifier with a differential input stage and an output current limited by the supply voltage. It is composed of four transistors, two of which are matched, and a constant-current source. The two input transistors act as differential amplifiers and the output transistor is a source follower that works as a linear amplifier. The current limiting bias current source prevents the output from saturating even when the supply voltage is very low. This current source also acts to reduce the internal supply voltage ripple on the bias current source of the output transistor, ensuring good linearity even when the supply voltage is low.

The TS464CPT is designed for use as a current-sensing amplifier, with excellent linearity and low temperature drift. The amplifier has a wide common-mode input voltage range from 0V to 0.5V beyond the supplies, which enables the amplifier to detect currents in either direction while also providing common-mode disturbances rejection. The output offset voltage of the amplifier is very low, and the wide bandwidth ensures good performance when used as a current-sensing amplifier.

The TS464CPT is an efficient and reliable current-sensing amplifier. It has excellent linearity and low temperature drift, allowing for precise current-sensing feedback for motor control systems. It also has a wide common-mode input voltage range, which allows for detection of current in both directions. The wide bandwidth ensures good performance, making it an excellent choice for current-sensing applications.
