OPA820IDBVR Datasheet

High Speed Operational Amplifiers


The OPA820IDBVR 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 OPA820IDBVR gives > 800MHz bandwidth with < 1dB peaking. The OPA820IDBVR complements this high-speed operation with excellent DC precision in a low-power device.A worst-case input offset voltage of &plusmn;750&mu;V and an offset current of &plusmn;400nA give excellent absolute DC precision for pulse amplifier applications. OPA820IDBVR Features &bull; High Bandwidth (240mhz, G = +2)&bull; High Output Current (&plusmn;110ma)&bull; Low Input Noise (2.5nv/&radic;Hz)&bull; Low Supply Current (5.6ma)&bull; Flexible Supply Voltage: Dual &plusmn;2.5v To &plusmn;6v Single +5v To +12v&bull; Excellent Dc Accuracy: Maximum 25&deg;C Input Offset Voltage = &plusmn;750&mu;V Maximum 25&deg;C Input Offset Current = &plusmn;400na
