OPA820

SBOS303A − JUNE 2004 − REVISED JULY 2004

Unity-Gain Stable, Low-Noise, Voltage-Feedback

Operational Amplifier

F_DEATURES

DESCRIPTION

HIGH BANDWIDTH (240MHz, G = +2)

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 750µV and an offset

current of 400nA give excellent absolute DC precision for

pulse amplifier applications.

HIGH OUTPUT CURRENT ( 110mA)

LOW INPUT NOISE (2.5nV/√Hz)

LOW SUPPLY CURRENT (5.6mA)

FLEXIBLE SUPPLY VOLTAGE

Dual 2.5V to 6V

Single +5V to +12V

EXCELLENT DC ACCURACY

Maximum 25°C Input Offset Voltage = 750µV

Maximum 25°C Input Offset Current = 400nA

Minimal input and output voltage swing headroom allow the

OPA820 to operate on a single +5V supply with > 2V 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.

A_DPPLICATIONS

LOW-COST VIDEO LINE DRIVERS

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.
