AC signal: 5,10, or 20 kHz (when the host MCU is RX24T)
AC current: +/- 35 mA (Max.)
Variable gain: Gain of 2, 4, 8, or 16.5
Correction of errors in the detected signals from the resolver
The angle signal with its phase delayed in proportion to the resolver angle is
output in response to the excitation signal.
Two amplifiers
Variable gain: Gain of 10 or 25
