The THS4502 and THS4503 are high-performance fully differential amplifiers from Texas Instruments. The THS4502, featuring power-down capability, and the THS4503, without power-down capability, set new performance standards for fully differential amplifiers with unsurpassed linearity, supporting 14-bit operation through 40 MHz. Package options include the 8-pin SOIC and the 8-pin MSOP with PowerPAD for a smaller footprint, enhanced ac performance, and improved thermal dissipation capability.
