TS912BIDT Application Field and Working Principle

The TS912BIDT is an integrated amplifier based on a monolithic low-power CMOS process and designed for sound signal applications. It is typically used in sound systems, including sound cards, audio amplifiers, sound smart phones, and other consumer audio applications. The TS912BIDT delivers high output power (1.2W), high input SNR, and low THD+N along with excellent EMC characteristics.The TS912BIDT features two single-supply operational amplifiers with Rail-to-Rail input/output stages. It provides high common mode rejection ratio and excellent temperature stability. It operates with a wide range of power supply voltages, from 3.5V to 10V. In addition, it has excellent current consumption and low output noise.The TS912BIDT amplifier consists of the following functional blocks. The differential inputs module and the operational amplifier, which are the main amplifier blocks, form the input stage. The power stage consists of two independent transistors and a Schottky diode. A pair of buffered outputs complete the output block of the amplifier.The design of the TS912BIDT is based on a differential amplifier topology, utilizing two symmetrical or oppositelybiased transistors. The input stage is configured with a resistive feedback network, which does not require any external components, greatly simplifying the overall design. The input stage provides a gain of about two in order to optimize the signal-to-noise ratio, while the output stage provides a gain of fifteen to amplify the signal to the required output power. The transistors are also mounted to an isolation layer that helps to reduce crosstalk and noise.The TS912BIDT offers a wide range of features that help to improve the overall performance of the amplifier. It has an adjustable gain, high input impedance, low distortion, and high linearity output. In addition, it has frequency-dependent compensation circuitry, which helps to reduce any undesired frequency response peaks. The temperature sensing and monitoring circuit helps to ensure that the amplifier can operate optimally over a wide range of temperatures.The TS912BIDT is ideal for use in professional audio applications. It is suitable for audio systems, soundcards, and consumer-level audio amplifiers. It is also suitable for use in electronic musical instruments, as well as in automotive applications.In conclusion, the TS912BIDT is an excellent choice for applications requiring low-power, high-performance amplifier solutions. It provides excellent noise rejection, input sensitivity, and output power characteristics. In addition, the amplifier design is simple and versatile, requiring no external components for its operation. The TS912BIDT is, therefore, an ideal choice for all applications that require a reliable amplifier solution.
