Introduction to TS934AIN

The TS934AIN is a high-performance amplifier circuit primarily used in applications such as audio, speech and signal processing. The TS934AIN is a unity-gain stable, low-noise, wide-bandwidth, and rail-to-rail output amplifier with a single-supply operation. It is manufactured in a low-voltage, high-speed process and is configured as an instrumentation amp, a buffer amp and an operational amplifier (op-amp).

Application Field

The TS934AIN is ideal for high-performance audio, speech, and signal processing applications. It is also suitable for low-noise instrumentation and buffer amplifier circuits, as well as impedance matching and buffering circuits. Its large open-loop gain, low input bias current, low input capacitance and wide bandwidth make it suitable for driving a variety of loads, including piezoelectric devices. Furthermore, its rail-to-rail output structure makes it capable of driving a wide range of single-ended signals without creating any over-saturation.

Working Principle

The TS934AIN is a two-stage op-amp configuration with a single-supply operational capability. The input stage comprises two low-noise, low-distortion amplifiers connected in a differential configuration. The feedback/buffering section consists of an adjustable voltage divider and a feedback amplifier in parallel. This combination provides a gain of unity that enables linear operation of the entire circuit, eliminating the need for a voltage amplifier. The output stage consists of a push-pull output stage with a rail-to-rail structure that allows output signals to range from ground to the supply voltage.

The TS934AIN is an ideal solution for a wide range of audio, speech, and signal processing applications that require a high performance amplifier with an extremely low noise floor and wide bandwidth. Its single-supply operation, low-noise input stage, and rail-to-rail output structure make it an excellent choice for many applications.
