DESCRIPTION
The THS4504 and THS4505 are high-performance
fully differential 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 8-pin SOIC and the 8-pin MSOP with
PowerPAD™ for a smaller footprint, enhanced ac
performance, and improved thermal dissipation
capability.
