LT LTM2893CY#PBF

容性耦合16000Vrms

Overview

The LTM2893IY-1PBF is a high speed isolated μModule (micromodule) SPI interface with ADC control signals. The LTM2893IY-1PBF is optimized for isolating 1Msps high resolution 18-bit SAR ADCs, such as the LTC2338 and similar families, and can interface with most general purpose ADCs. The LTM2893-1 is optimized for isolating the LTC2348 and similar families of simultaneous sampling ADCs that require writing configuration settings into the ADC. LTM2893IY-1PBF isolates the conversion start, sampling signal, with very low aperture jitter (30ps) and low latency (20ns).

The isolation barrier tolerates large voltage ground variations between the logic interface and the isolated side of the LTM2893. Uninterrupted communication is maintained during voltage transients greater than 50kV/μs.
