Some Power Figures


This is the power consumption of some common devices
LPC11U35: 7mA (50MHz), 2mA (12MHz), 300uA (deep sleep)
LM75B (thermometer, i2c): 280uA, 4uA
MCP9700 (thermometer, analogue): 6uA
SPI flash: 40mA/10mA/20uA
I2C eeprom: 2mA/0.5mA/1uA
20bit ADC: 200uA/20uA
4ch DAC: 800uA
Voltage reference: 140uA

Clearly, we can easily get over 1mA while doing nothing
