I'm trying to use AD8555 chip with strain gauge transducer.
I connected AD8555 as shown at Figure 60 of datasheet (with 5V supply).
Without any connections to VPOS and VNEG pins I have high signals at VNEG pin (about 2,35 V) and at DIGIN pin (about 1 V).
At DIGOUT pin I have 4.97 V.
Is it correct behavior of the chip?
With high level at DIGIN pin I can not to program the chip.
