Description
iC-Haus iC-MNF
iC-Haus iC-MNF is a 3-channel, sine-to-digital converter for interpolating sin/cos sensor signals using a high-precision SAR converter with a selectable resolution of up to 14 bits. Each input has a separate sample-and-hold stage, which halts the track signal for the subsequent sequential digitization. Various 2- and 3-track Vernier scale computations and multiturn gear box synchronization modes can be configured for the calculation of high-resolution angle positions with resolutions of up to 26 bits.
