Quiz: How Well Do You Know Adaptive Power Switching?
Is your I/O module overheating? The AD74416H's Adaptive Power Switching (APS) can cut heat dissipation by up to 40% — but how well do you really understand how it works?

Hello everyone
I want to use LTM2893 to isolate SPI I/F for AD7983, is AD7983 compatible with the LTM2893?
On the datasheet of LTM2893, It is mentioned LTM2893 is optimized for isolating 1Msps high resolution 18-bit SAR ADCs, but these are only some suited legacy LTC ADCs on datasheet.
Do you have any recommended legacy ADI ADCs which can work well with LTM2893?

Hello QI,
The AD4000 family should work with the LTM2893. I've successfully operated the AD4003 with the LTM2893. The AD4003 is an 18-bit 2Msps SAR.
You'll need to operate the AD4003 in the chip-select 3-wire with busy indicator mode and configure the LTM2893 to use a 100MHz SCK2 frequency, 1 word count and a 20-bit word size. Note that the valid data is in the lower 18-bits. Here's an example circuit to illustrate the connections between the AD4003 and LTM2893.
