- CH4 spindle drive part
APPLICATION SUMMARY (Continued)
CH4 drive part is composed V-I converter and output power amplifiers.
- The V-I converter converts the input voltage applied to pin24 into a incremental output current given
- These sourcing and sinking output current from V-I converter are delivered to output power amplifiers,
- The differential voltage gain is, then, calculated as follows:
by
