Features - Renesas RAA3064002GFP User Manual

RAA3064002GFP/RAA3064003GFP
Renesas CMOS ICs
Resolver-to-Digital Converters
Intended for use with a single-phase excitation input and two-phase output type resolver sensor
Frequency of the excitation signal is selectable from 5 kHz, 10 kHz, and 20 kHz.

Features

Intended for use with the host MCU, this IC chip

converts signals (electrical angle information)
detected by the resolver sensor (angle sensor) to
digital signals.
Connectable to a transformer-type or current-
