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.
