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…
Part Number: AFE7225 Other Parts Discussed in Thread: THS4552 ,
Hi TI support team,
We have connected AFE7225 VCM output to total four places of ADC input channel VCOM pin of THS4552 Opamp.
Could you please clarify the output current capability of VCM…
Part Number: AFE7225 Hi TI Team,
There is no any layout guidelines provided in IC datasheet and also not found any separate document. Could you please provide the same.
Pradeep:
I think the missing step is actually loading the desired DAC level into the register. This is done in registers 0x243 and 0x244 (for Aux DACA). The default will be 0. 0xFFF corresponds to a maximum value. Then you have to enable the loaded register…
Part Number: AFE7225 Other Parts Discussed in Thread: AFE7222 , Hello team,
I am working with a customer that wants to use the AFE7225 or AFE7222 as the ADC for their scope application (they also need the DAC, and would prefer to go with a single integrated…
Part Number: AFE7225 Other Parts Discussed in Thread: ADS8910B , Hi TI Team,
As per the attachment document, For ADS8910B part there is a recommendation for AA filter Cflt and Rflt component values. But in AFE7225 IC we have not found any recommendation for…
Part Number: AFE7225 Hi TI support Team,
In AFE datasheet Figure 2-2 and Table 2-2 mentioned pin names are not matching. Please let me know which one is proper and which one we need to follow in our design.
Part Number: AFE7225 Hi Team,
AFE DAC output voltage range is referenced with AVDD3_DAC+/- 0.5V supply and as per the section 9.9, 1VPP swing available in each DAC output pin. So it means the total 2VPP differential output voltage we will receive across…
