DESCRIPTION
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 SOIC-8 and the MSOP-8 with PowerPAD™ for a
smaller footprint, enhanced ac performance, and
improved thermal dissipation capability.
