Integrated Circuits AD2S1210 AD2S1210BSTZ 16Bit Rotary Encoder/RDC/resolver Acquisition Module

Complete AD2S1210 Resolver-to-Digital Converter Module

• Onboard SEPIC converter supporting wide input voltage range (2.7-8VDC)
• 16-bit resolution per electrical degree
• Supports SPI serial interface, parallel interface, and quadrature encoder output
• Compatible with both magnetoresistive resolvers and split-type resolvers
• Flexible excitation source configuration (frequency and amplitude adjustable)
• Reference firmware provided.

FAQs:
Q: How to measure excitation signals with an oscilloscope?
A:

• Recommended method: Use differential probes between EXC+ and EXC-
• Alternative method: With standard probes, measure EXC+ and EXC- separately using two oscilloscope channels, then use the "math function" to subtract the two channels

Q: What is the excitation signal amplitude?
A:

• The RDC typically operates properly across wide frequency and amplitude ranges
• Optimal excitation amplitude and frequency ensure better noise performance and lower power consumption
• Default excitation amplitude: 6.4Vpp (for 1210 module)

• Note: Hardware parameter modification required for amplitude adjustment (refer to 1210 module schematic)

Key Features:

• High-precision 16-bit angular measurement
• Dual-interface design (SPI/Parallel) for flexible system integration
• Universal resolver compatibility
• Configurable excitation parameters
• Ready-to-use reference implementation
