ADC3662: The differences between ADC3662 and ADC3663

Part Number: ADC3662
Other Parts Discussed in Thread: ADC3663,

When using the two ADC conversion chips ADC3663 and ADC3662, I found that ADC3663 can operate in a 2-wire 16-bit mode, but ADC3662 cannot operate in a 2-wire 16-bit mode no matter how it is configured. Does ADC3662 support a 2-wire 16-bit output mode? If it does, which registers need to be configured？

Hi，

Please refer to the following product comparison page，

https://www.ti.com/compare-products/?id=2020&type=GPT&partList=ADC3662,ADC3663&columnList=157max,84,1028,1918,300,2192,1498,1034,1130,989typ,89,88,1039,873,-4

If you want to configure ADC3662 as a 2-wire 16-bit device, you can refer to "8.3.5.4 Output Interface/Mode Configuration" on page 48 of the data sheet，

https://www.ti.com/lit/ds/symlink/adc3662.pdf#page=48

For example, register 0x07 should set to 0x4b to configure the part in 2w, 16b mode - once the initialization sequence is programmed in, a readback of register 0x07 will be 0x00. If register 0x07 is later written to, a readback will be the value that was written in. You will need to do steps 1 & 2 (register writes to 0x07 and 0x13) every time after power up.
