The advantages in high-speed analog signal processing device pins include two inputs (VIN+, VIN–), two systems, including immunity to external outputs (VOUT–, VOUT+), two power supplies (VS+, VS–), common-mode noise, suppression of even-order an output common-mode control pin (VOCM), and an nonlinearities, and increased dynamic range. Fully optional power-down pin (PD). differential amplifiers not only serve as the primary means of providing gain to a differential signal chain, but also provide a monolithic solution for converting single-ended signals into differential signals for easier, higher performance processing. The THS4500 family of amplifiers contains products in Texas Instruments' expanding line of high-performance, fully differential amplifiers. Information on fully differential amplifier fundamentals, as well as implementation specific information, is presented in the Applications Section of this data sheet to provide a better understanding of the operation of the THS4500 family of devices, and to simplify the design process for Figure 97.
