Introduction of THS7373IPW

The THS7373IPW is a high speed and low noise video amplifier integrated circuit (IC) from Texas Instruments. It is designed for wide-band, high gain applications such as buffer amplifiers, variable gain amplifiers, and active filters. This IC is suitable for both digital and analog applications. The THS7373IPW is fabricated from advanced SiGe BiCMOS process and provides superior performance over a wide temperature range (-40ºC to +125ºC).

Features of THS7373IPW

The THS7373IPW is a low distortion video amplifier that offers high input impedance and high gain flatness. It features low gain variation over temperature and low input capacitance. Additionally, it offers high input and output impedance, low harmonic distortion, and wide bandwidth. The THS7373IPW provides output power of 5 dBm (1Vrms) and maximum gain of +25 dB. It can drive up to 50mA peak output current, and is also equipped with several user-selectable features such as gain control, gain stability, slew rate control, and power supply options.

Application field and Working Principle

The THS7373IPW is a high performance, ultra-low noise amplifier that is suitable for high gain applications. Its wide bandwidth and low distortion make it suitable for use in a variety of applications such as in TV set-top box receivers, digital video amplifiers, digital video filters, and digital video recorders. The THS7373IPW is an power amplifier whose output power is determined by a number of factors, such as the load, gain, bandwidth and slew rate. The amplifier’s slew rate controls how fast the voltage can be changed within a certain domain of time. The amplifier’s gain is determined by the ratio between the output voltage and the input voltage. The THS7373IPW operates on a single positive voltage and consumes minimal current, making it ideal for battery operated products. The amplifier’s input stage is composed of a differential input pair, which consists of two bipolar transistors. The output stage is composed of multiple bipolar transistors, which are connected in an L-type configuration. The amplifier’s gain is adjusted by controlling the base-emitter current of the transistor. The base-emitter current is in turn controlled by the voltage present at the amplifier’s adjust terminal. The amplifier’s gain can also be controlled by adjusting the amplifier’s bandwidth using the bandwidth pin. The bandwidth pin is also used to turn on and off the amplifier’s slew rate control. The amplifier’s power supply pin is used to enable or disable the amplifier. The THS7373IPW is an ideal solution for applications such as video production equipment, digital video filters and video amplifiers, digital tv receivers, video optical instrumentations and wireline local loop applications. Its wide bandwidth and high gain make it suitable for applications requiring wide dynamic range and low distortion. Its low power consumption and compact size also make it ideal for a variety of small form-factor products.
