Description

Demonstration circuit 2405A shows an LTM®2893 isolatingand interfacing an LTC®2328-18. The LTM2893 is a highspeed SPI isolator for interfacing read only ADCs with afull complement of control signals. The LTC2328-18 is alow noise, high speed 18-bit successive approximationregister (SAR) ADC. Low noise isolated power is deliveredto the isolated side with an LT3999 push-pull driver andisolation transformer.
