LPC804

32-bit Arm Cortex-M0+ microcontroller

[1] Characterized though limited samples. Not tested in production.

[2] All peripherals except comparator, temperature sensor, and FRO turned off.

14.4 DAC

[1] Typical ratings are not guaranteed. The values listed are for room temperature (25 C) and

VDD = VDDA = 3.6 V.

[2] Characterized through bench measurements, not tested in production.

[3] DAC output voltage depends on the voltage divider ratio of the ROUT and external load resistance.

Table 29. Comparator voltage ladder reference static characteristics

VDD = 1.8 V to 3.6 V. Tamb = -40 C to + 105C; external or internal reference.
