DESCRIPTION
The OPA2686 provides two very low noise, high gain
bandwidth, voltage feedback op amps in a single
package. Operating from a low 12mA/channel quies-
cent current, each channel provides a 1.4nV/鈭欻z input
voltage noise with a 1.6GHz gain bandwidth product.
Minimum stable gain is specified at +7V/V while
exceptional flatness is guaranteed at a gain of +10.
The combination of low noise, high slew rate
(600V/碌s), and broad bandwidth allow exceptional xDSL
differential receivers to be implemented. Additionally,
de-compensated, low-noise voltage-feedback op amps
are ideal for broadband transimpedance requirements.
The dual channel OPA2686 provides matched channels
for high speed differencing transimpedance require-
ments. With over 200MHz bandwidth at a gain of
20dB, excellent gain and phase matching is provided at
IF frequencies for matched I and Q channel amplifiers.
