The AMC1210 modular evaluation module (EVM) provides four modulator channels from the ADS1204 for
the AMC1210. Two are designated for resolver applications and two are designated for current
measurements. All interface modes of the AMC1210 are provided.
The new modular EVM form factor allows for direct evaluation of the AMC1210’s performance and
operating characteristics. This EVM is compatible with the HPA-MCU Interface Board (
SLAU106 ) from
Texas Instruments.
•
Four modulator channels provided by ADS1204
•
All AMC1210 interface modes available
•
Direct operation with a variety of DSK and microcontroller platforms from Texas Instruments
•
All four ADS1204 channels have an input range of 0 V to 5 V.
The AMC1210 modular EVM is designed for easy interfacing to resolvers and current sensors. Connector
J05 is a 9-pole DSUB jack for easy connection to standard resolvers. To hold the floating resolver inputs
to a predefined common mode level, a 2.5-V voltage is added on the resolver inputs.
