Part Number : SCADC12F.C35
Overview :
The Macro Cell SCDAC12F.C35 is a 12-Bit SAR analog to digital converter. The architecture is based on a charge redistribution switched capacitor main-DAC for the MSBs and a resistor string sub-DAC for the LSBs.
The inherent track-and-hold operation of the input stage avoids the need for additional sample-and-hold stages. At the beginning of the tracking phase the whole main-DAC is recharged. This causes high input current peaks.
Features : - Resolution 12 Bit
- Maximum Sampling Rate 1.5MSample/sec
- Supply Range between 2.7 V and 3.6 V
- Wide Junction Temperature Range from -40 °C to +125 °C
- Negative Reference Voltage (VREFN) Range from 0.825V to 1.475V at 3.3V Supply
- Positive Reference Voltage (VREFP) Range from 1.825V to 2.475V at 3.3V Supply
- Reference Voltage Difference (VREFP-VREFN) must be greater than 1V at 3.3V Supply
- Negative and Positive Analog Input Voltage Range from 0V to 3.3V at 3.3V Supply
- Full Scale Range ±(VREFP-VREFN) at 3.3V Supply
- SE: Negative Analog Input Voltage must be set to (VREFP+VREFN)/2 at 3.3V Supply
- Total Power Consumption typical 8mW maximum 12mW
