• GAIN = +2V/V BANDWIDTH (850MHz)

The OPA2695 is a dual, very high bandwidth,

• LOW POWER: 129mW/channel

have been optimized to provide symmetrical input

• LOW DISABLED POWER: 0.5mW/channel

and output paths. This architecture makes the

OPA2695 an ideal choice as a differential driver, such

as for a high-speed analog-to-digital converter (ADC).

• VERY WIDEBAND ADC DRIVERS

The OPA2695 low 12.9mA/channel supply current is

precisely trimmed at +25

°C. This trim, along with a

low temperature drift, gives low system power over

with the optional disable control pin. Leaving this pin

open, or holding it high, gives normal operation. If

pulled low, the OPA2695 supply current drops to less

than

µA/channel. This power-saving feature,

along with exceptional single +5V operation, makes

the OPA2695 ideal for portable applications. The

OPA2695 is available in an SO-8 (without disable)

package or QFN-16 package (with disable).
