DDC introduces the RD-19231 series of 16-bit resolver-to-digital (R / D) converters https://www.automation.com/files/pluginfiles/item_99547/field_376/ddc_reg.jpg
30. October 2018 - Data Device Corporation (DDC) announced the launch of its RD-19231 series of 16-bit resolver-to-digital (R / D) converters offering 3.3V or 5V compatibility and positioning systems in the market Aerospace, industry and commerce. Replaced with all RD-19230 legacy designs, the RD-19231, which is included in a 64-pin plastic (10 mm x 10 mm) flat-pack plastic pack, does not require any PCB modification , This monolithic chip with SOI CMOS combines precise analog circuits with digital logic into a complete tracking R / D converter with an accuracy of up to 1 arc minute. The RD-19231 provides user programmable encoder emulation, resolution, bandwidth, tracking rate, speed scaling, and a new selectable I / O voltage output of 5V or 3.3V. It also provides internal encoder emulation (with independent resolution control) The RD-19231 emulates incremental optical encoder output so that new encoder-based systems can now communicate with a resolver output.
The synthesized reference capability of the RD-19231 eliminates errors caused by the quadrature voltage (phase shift) and also ensures operation with a phase shift of up to 45 degrees. In addition, the RD-19231's differential resolver inputs allow filtering in noisy environments.
The RD-19231 accepts two sets of bandwidth components for a variety of dynamic applications. The Dual Bandwidth feature also allows users to quickly change the resolution between 10, 12, 14 or 16-bit settings, minimizing speed and position information. Speed scaling, reverse error and offset parameters can be externally adjusted for applications that require stricter specifications than the standard.
Operating at temperatures from -40 ° C to + 85 ° C, the RD-19231 series is suitable for aerospace, industrial and commercial position applications, including servo motor controls, antenna positioning, aircraft position feedback systems, machine tool and robot positioning controls, and manufacturing process control systems.
