Features:
OPA2891 is an ultra-low voltage noise, high-speed voltage feedback amplifier that is highly suitable for applications that require low voltage noise, including communication and imaging. The dual channel amplifier OPA2891 provides excellent AC performance with a bandwidth of 140MHz, gain (G)=2V/V, slew rate of 105V/µ s, and stabilization time of 70ns (0.1%). OPA2891 has stable unity gain and a bandwidth of 180MHz. OPA2891 has a total harmonic distortion (THD) of -100dBc at f=1MHz and ultra-low noise of 0.95nV/√ Hz, designed specifically for applications that require low distortion and low noise, such as buffered analog-to-digital converters.
