Description for the OPA2846
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.
