• 16-bit precision: 3 channels (Carrier frequency: 62.5 kHz)
• 8-bit precision: 3 channels (Carrier frequency: 62.5 kHz)
3-wire serial I/O: 2 channels
• BUSY/STRB control available (only 1 channel)
8-bit resolution × 12 channels, conversion time: 10 µs
Note It is possible to change the capacity of the internal PROM and the internal RAM by specifying the internal
memory capacity select (IMS) register.
