Overview
CM1103 is a high-precision, low-power, I2C-compatible, 16-bit ΔΣ ADC, which integrates an internal low-drift voltage reference, an oscillator, a programmable gain amplifier (PGA), and a digital comparator.
The CM1103 can perform conversion operations at a rate of 2kSPS. The PGA provides a programmable input voltage range from ±256mV to ±6.144V, and the input multiplexer (MUX) offers 4 single-ended inputs and 2 differential inputs. The digital comparator provides over-voltage detection.
The CM1103 can operate in either single-conversion mode or continuous conversion mode. In single-conversion mode, the device automatically enters power-down mode after completing one conversion, significantly reducing current consumption during idle states
