FEATURES

12 V, 15 V

Include the Negative Power Supply Rail

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 8-pin

SOIC and the 8-pin MSOP with PowerPAD

 for a

smaller footprint, enhanced ac performance, and

improved thermal dissipation capability.
