† Not production tested, limits characterized

NOTES:

1. The sensor current ISENSOR is consumed if (ADC12ON = 1 and REFON=1), or (ADC12ON=1 AND INCH=0Ah and sample signal

is high). When REFON = 1, ISENSOR is already included in IREF+.

2. The temperature sensor offset can be as much as

±20_C. A single-point calibration is recommended in order to minimize the offset

error of the built-in temperature sensor.

3. The typical equivalent impedance of the sensor is 51 k

Ω. The sample time required includes the sensor-on time tSENSOR(on)

4. No additional current is needed. The VMID is used during sampling.

5. The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.

NOTES:

1. No load at the output pin, DAC12_0 or DAC12_1, assuming that the control bits for the shared pins are set properly.

2. Current into reference terminals not included. If DAC12IR = 1 current flows through the input divider; see Reference Input

specifications.

3. PSRR = 20*log

{ΔAVCC/ΔVDAC12_xOUT}.

4. VREF is applied externally. The internal reference is not used.
