AD8352 SPICE Model and Input Voltage Range

eti_ch on Dec 23, 2018

Hello,

I'm planning a DC coupled front-end for the AD9434 12-Bit ADC using the AD8352 Fully Differential Driver, as recommended in the datasheet and indicated in Fig. 43 in the AD9434 datasheet.

Since I will use the AD8352 in a single-ended to differential configuration with an input signal symmetric around GND, I am interested about the input voltage range when using

a) symmetric +-2.5V supplies

b) asymmetric +3V, -2V supplies

c) +5V, 0V supply

which I could not find in the corresponding datasheet

Is there a SPICE model available?

Thanks and regards

Hi,

The nominal input common-mode voltage needs to be 1.9 V with respect to the negative supply, so for the three cases in the question, it needs to be at:

a) 1.9 - 2.5 = -0.6 V

b) 1.9 - 2 = -0.1 V

c)
