DESCRIPTION
The THS4304 is a wideband, voltage-feedback operational amplifier designed for use in high-speed analog
signal-processing chains operating with a single 5-V power supply. Developed in the BiCom3 silicon germanium
process technology, the THS4304 offers best-in-class performance using a single 5-V supply as opposed to
previous generations of operational amplifiers requiring 5-V supplies.
The THS4304 is a traditional voltage-feedback topology that provides the following benefits: balanced inputs, low
offset voltage and offset current, low offset drift, high common mode and power supply rejection ratio.
The THS4304 is offered in 8-pin MSOP package (DGK), the 8-pin SOIC package (D), and the space-saving 5-pin
SOT-23 package (DBV).
