Brady,
You are correct in that it doesn't specify a max rating for the DAC output directly but it cannot exceed the AVDD3 abs max value which is 3.6V.
It appears that the DAC output is still on with a current draw to hold the output at mid-code.

Part Number: AFE7225 The docs cover DFS_RX and DFS_TX which seem limited to LVDS-only (DFS_TX is in 5.7 - LVDX TX INPUT INTERFACE REGISTERS, and DFS_RX is in 5.8 - LVDS RX OUTPUT INTERFACE REGISTERS).
Is there a CMOS equivalent? The documentation is lacking…

Hi,
As per the current sync DAC requirement, We have given 71.5 ohm pullup to P5V0 and 165 ohm pull-down to ground to maintain 50ohm impedance in AFE DAC output (IOUTP/N_A_DAC and IOUTP/N_B_DAC).
In assembled board, Due to this pullup…
Part Number: AFE7225 For the DAC LVDS signals, that are labeled with non-reused CMOS names in Table 2-2 (why change some but not all?), the pin name's indicated polarity matches with the desription, but the ADC LVDS lines appear to have reversed polarity…
Part Number: AFE7225 Hi,
In recent post I asked if AFE7225 can handle 160MHz signal.
The answer was "if it is instantaneous bandwidth of 160MHz, ii can not"
Here my application is 160MHz is the IQ data(I+, I-, Q+, Q-) coming from RF down converter…
Part Number: AFE7225 Other Parts Discussed in Thread: AFE7700 Hi,
I have baseband TX and RX signals with BW up to 160MHz, can AFE7225 handle them from ADC/DAC bandwidth point of view?
THanks, Tiejun
Part Number: AFE7225 Hi All,
I want to configure AFE7225 with python spidev (it sends 8 bit per transaction).
AFE7225 has 12 bit wide address and 8 bit wide data.
Would AFE work properly if I send 24 bits to the chip via spidev (12 addr + 8 data + 4 zeros…
Part Number: AFE7225 Hi TI Support team,
We are configured both AUXDAC_A and AUXDAC_B channels with same external and internal termination resistor values and written same values for both 0x248 and 0x249 registers. But the measured voltage is not…
Part Number: AFE7225 Other Parts Discussed in Thread: ADC3224 , DAC3174 , ADS4249 , AFE7070 Hello Guys,
Good day.
Is AFE7225 applicable for marine VHF wireless transceiver application for marine frequencies from 156 to 162 MHz? Or is there a better alternative…
