Product Introduction

The OPA4820 provides a very low input noise voltage, high output using a low supply current current of 5.7mA/ch wideband, stable unity gain, voltage feedback amplifier. 在单位增益时，OPA4820使>和 This OPA4820 complements the precision and high-speed operation of this DC low-power device with excellent precision. The worst-case input offset voltage is ± 0.8mV and ± 500nA offset current for excellent absolute pulse amplifier application DC accuracy.

Minimal input and output voltage swing headroom allows OPA4820 to operate at a single +5 V with > 2VPP output swing supply. 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.
