Our device should work with wide temperature range, but in datasheet at ADA4927-1 / ADA4927-2 we've found that:
The power-down feature should not be used in applications in which the ambient temperature falls below 0°C. Contact sales for information regarding applications that require the power-down feature to be used at ambient temperatures below 0°C.
We need power-down feature work at temperatures below 0°C. What can be done for it?
Apologies for responding late.
Unfortunately, ADA4927-X PowerDown does not work well in cold temperatures. That means the part will power down but it will take a long time to power up.
Thanks for your answer.
But what means: Contact sales for information regarding applications that require the power-down feature to be used at ambient temperatures below 0°C ?
Do AD have alternatives for ADA4927-X with full-functional Power Down feature? Can you recommend an alternative? It is necessary that the power supply will be bipolar (+-3.3V), bandwidth at least 500 MHz with a gain = 2, the operating temperature range -40 to +85 °C or wider, the ability to quickly switch to a power down mode at any temperature, the minimum consumption in active mode.
