When in byte mode, the AD7938 channel ID is read on DB4 to DB6 when HBEN is high. How do you read the channel number when in Word Mode ?
It is only possible to read the channel ID in byte mode.
We are using AD7938 for a multi-channel A/D conversion. I wanted to know what can be the implication of not fully respecting the minimum 30 ns Quiet time requirement ?
I have a test board with the AD7938BCPZ-6 part. I have it set up in byte mode. I have an FPGA that controls the read, write and conversion control signals. Every read cycle returns all 1's on the databus. I am operating the device using a 3.3V supply…
In the datasheet of AD7938, Throughput rate is 1.5MSPS
If it works in 8-channel single-ended inputs mode, Throughput rate of each channel is 1.5MSPS or (1/8)*1.5MSPS?
I am facing an interesting issue. I have designed an RTL module with the AD938 A to D. I am referencing an external source 4.096V I am able to read channels so I think my logic is correct. So, let's say I have channel 1 at 4 v my reading…
AD7938 手册上写的1.5MSPS采样率 ，实际应用种能到多少MSPS?
如果用满8个通道同时采样,每个通道是1.5MSPS 还是(1/8) * 1.5MSPS ?
Our customer will run the mode 2, parallel interface.They want to control /CS and /RD signal at same time.The "60ns" setup time is necessary?
AD7875t15: 60 ns min CS to RD setup time (Mode 2)t18: 0 ns min CS to RD hold time …
