The THS4504 and THS4505 are high-performance, fullydifferential amplifiers from Texas Instruments. The THS4504, featuring power-down capability, and the THS4505, without power-down capability, set new performance standards for fully differential amplifiers with unsurpassed linearity, supporting 12-bit operation through 40 MHz. Package options include the SOIC-8 and the MSOP-8 with PowerPAD for a smaller footprint, enhanced ac performance, and improved thermal dissipation capability.
