LPC5410x

32-bit ARM Cortex-M4/M0+ microcontroller

[1]

Characterized through simulation. Not tested in production.

[2]

The ADC default sampling time is 2.5 ADC clock cycles. To match a given analog source output

impedance, the sampling time can be extended by adding up to seven ADC clock cycles for a maximum

sampling time of 9.5 ADC clock cycles. See the TSAMP bits in the ADC CTRL register.

Zo = analog source output impedance.
