Description

The OPA4820 provides a wideband, unity–gain stable, voltage–feedback amplifier with a very low input noise voltage and high output current using a low 5.7mA/ch supply current. At unity–gain, the OPA4820 gives > 600MHz bandwidth with < 1 dB peaking. The OPA4820 complements this high–speed operation with excellent DC precision in a low–power device. A worst–case input offset voltage of ±0.8mV and an offset current of ±500nA give excellent absolute DC precision for pulse amplifier applications.

Minimal input and output voltage swing headroom allow the OPA4820 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 quad pinout SO–14 package while emerging high–density portable applications can use the TSSOP㪦.
