www.ti.com THS4304 SLOS436A – MARCH 2004 – REVISED JULY 2004 Wideband Operational Amplifier FEATURES Wide Bandwidth: 3 GHz High Slew Rate: 830 V/µs Low Voltage Noise: 2.4 nV/√Hz Single Supply: 5 V, 3 V Quiescent Current: 18 mA APPLICATIONS Active Filter ADC Driver Ultrasound Gamma Camera RF/Telecom 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).
