DESCRIPTION
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
鹵750碌V
and an offset
current of
鹵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 > 2V
PP
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擄) 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 industry鈥檚 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.
