Product Introduction

The OPA820 offers a very low input noise voltage, high output using a low supply current current of 5.6 mA broadband, stable unity gain, voltage feedback amplifier. 在单位增益，给出了OPA820>和 The OPA820 complements this excellent DC low-power device with high accuracy and high-speed operation. The worst-case input offset voltage is ±750μV and ± 400nA offset current for excellent absolute pulse amplifier application DC accuracy.

Minimal input and output voltage swing headroom allows the OPA820 to operate on a single +5 V swing supply > 2V PP output. Although it is not a rail-to-rail (RR) output, this will support most emerging swings at lower power consumption than typical RR output op-amp noise analog-to-digital converter (ADC) input range.
