DESCRIPTION
The OPA2846 provides two very low-noise, high gain
bandwidth, voltage-feedback op amps in a single
package. Operating from a low 12.6mA/channel quiescent
current, each channel provides a 1.2nV/√Hz input voltage
noise with a 1.65GHz gain bandwidth product. Minimum
stable gain is specified at +7V/V while exceptional flatness
is ensured at a gain of +10V/V.
The combination of low noise, high slew rate (600V/μs)
and broad bandwidth allow very high SFDR differential
receivers to be implemented. Additionally, decompensated,
low-noise, voltage-feedback op amps are ideal for
broadband transimpedance requirements. The dual channel
OPA2846 provides matched channels for high-speed
transimpedance requirements. With over 200MHz bandwidth
at a gain of 20dB, excellent gain and phase matching
are provided at IF frequencies for matched I and Q channel
amplifiers.
