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-14.
