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
±
750
μ
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 > 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
°
) 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’s 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.
