I am using the AD8139 in the as shown in the attached PDF.
Spice simulations work fine. But On the bench using +-5V supplys, AD8138 outputs Nothing.
What did I do wrong.

AD8139
Recommended for New Designs
The AD8139 is an ultralow noise, high performance differential
amplifier with rail-to-rail output. With its low noise, high
SFDR, and wide bandwidth, it...

I am not able to take voltage readings. We replaced the AD8139s, with AD8138s, and sent the boards to the customer.
They are aware of the switch but very much want the higher temp AD8139s, ASAP.
The VAC is 0.600V p-p, VCM = 0.36V DC.
Supply Voltages:
V+ = 5V V-= -5V.
