Hi Eli,

While we don't have an exact match for the ADI device, can you tell me more about your design/low power application?

Hi,

Its a video board with 8 chanel 14bit A/D like ADS5294.

Customer prefer to use FDA with integrated resistors soluton,Gain=0.5,,and need low power consumption.

Hi,

I'm jumping in here.

Is LMP7312 (Precision SPI-Programmable AFE with Differential/Single-Ended Input/Output) an option? It draws 2mA maximum supply current, 1MHz gain-bandwidth, and the gain setting resistors are internal. It does require SPI for control.

Just a thought.

Regards,

Hooman
