| IC revision | 1 |
Description
Demonstration circuit DC2589A shows an LTM®2895isolating and interfacing an LTC®2642-16. The LTM2895is a high speed SPI isolator for interfacing DACs witha full complement of control signals. The LTC2642-16is a bipolar 16-bit unbuffered voltage output DAC. Lownoise isolated power is delivered to the isolated side witha LT®3999 push pull driver and isolation transformer.The DC2589A demonstrates the DC and AC operation ofthe LTC2642-16 without performance degradation whenisolated with the LTM2895. The serial peripheral interface(SPI) runs at a maximum 100MHz SCK frequency. TheLTM2895 is configurable with many DACs with SPI clockfrequencies up to 100MHz.The DC2589A connects to either the DC590 or DC2026for control with QuikEval™.
