AMC1204
Description
The AMC1204 and AMC1204B are 1-bit digital output, isolated delta-sigma (ΔΣ) modulators that can be clocked at up to 20 MHz. The digital isolation of the modulator output is provided by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference.
Key Features
- 1 ±250-mV input voltage range optimized for shunt resistors
- High electromagnetic field immunity (see SLLA181A application report)
- Outstanding AC performance: – SNR: 84 dB (minimum) – THD: –80 dB (maximum)
- Excellent DC precision: – INL: ±8 LSB (maximum) – Gain Error: ±2% (maximum)
- External clock input for easier synchronization
- Fully specified over the extended industrial temperature range
