The THS4500 and THS4501 are high-performance fully
differential amplifiers from Texas Instruments. The
THS4500, featuring power-down capability, and the
THS4501, 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.
