HIGH BANDWIDTH: 300MHz (G = +10)  
LOW INPUT VOLTAGE NOISE: 1.2nV/Hz  
VERY LOW DISTORTION: –100dBc (5MHz)  
HIGH SLEW RATE: 600V/µs  
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.  
HIGH DC ACCURACY: V = 150µV  
IO  
LOW SUPPLY CURRENT: 12.6mA/ch  
HIGH GAIN BANDWIDTH PRODUCT: 1650MHz  
STABLE FOR GAINS +7V/V  
The combination of low noise, high slew rate (600V/µs)  
and broad bandwidth allow very high SFDR differential  
receivers to be implemented. Additionally, decompen-  
sated, low-noise, voltage-feedback op amps are ideal for  
broadband transimpedance requirements. The dual chan-  
nel OPA2846 provides matched channels for high-speed  
transimpedance requirements. With over 200MHz band-  
width at a gain of 20dB, excellent gain and phase matching  
are provided at IF frequencies for matched I and Q channel  
amplifiers.
