Nity-Gain Stable, Low-Noise, Voltage-Feedback Operational Amplifier

The OPA820 provides a wideband, unity-gain stable, voltage-feedback Amplifier with a very low input noise voltage and high output current using a low 5.6mA supply current. At unity-gain, the OPA820 gives > 800MHz bandwidth with < 1dB peaking. The OPA820 complements this high-speed operation with excellent DC precision in a low-power device. A worst-case input offset voltage of 750??V and an offset current of 400nA give excellent absolute DC precision for pulse Amplifier applications. Minimal input and output voltage swing headroom allow the OPA820 to operate on a single +5V supply with > 2VPP output swing. While not a Rail-to-Rail (RR) output, this swing will support most emerging Analog-to-digital converter (ADC) input ranges with lower power and noise than typical RR output op amps Exceptionally low dG/dP (0.01%/0.03) supports low-cost composite Video Line Driver applications. Existing designs CAN use the industry-standard pinout SO-8 package while emerging high-density portable applications CAN use the SOT23-5. Offering the industrys lowest thermal impedance in a SOT package, along with full specification over both the commercial and industrial temperature ranges, gives solid performance over a wide temperature range.
