Resolution 1Msps ADCs Reads Data
at 100MHz, Serves Multiple ADCs
Brian Jadus The ideal isolator for an analog-to-digital converter (ADC) is
one that is invisible. It manages all the control and data signals,
maximizes the sampling rate and minimizes the effects of
jitter on SNR performance. The LTM2893 ВµModule isolator
achieves these goals for ADCs with SPI interfaces, in the
1Msps range, and supports a 6000VRMS isolation rating.
Reading data from high resolution successive approximation register (SAR) analog-to-digital converters
through a digital isolator is limited with more traditional options. When reading from a serial peripheral interface (SPI) most high speed digital isolators
max out at 25MHz, with a few specialty devices
operating up to 40MHz. The LTMВ®2893 reads data
at up to 100MHz, is flexible, and handles multiple
ADCs solving the timing issues and limitations of
standard digital isolators interfacing to SAR ADCs. …
