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 6.8-mA supply current. The OPA820 complements this high-speed

operation with excellent DC precision in a low-power device. A worst-case input offset voltage of ±3.5 mV and an

offset current of ±700 nA give excellent absolute DC precision for pulse amplifier applications.

Minimal input and output voltage swing headroom allow the OPA820 to operate on a single 5-V supply with >

2V_PPoutput 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.

The OPA820 is characterized for operation from –55°C to 210°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
