  * AnalogIn does a single conversion when you read a value (actually several conversions and it takes the median of that).
  * This library runns the ADC conversion automatically in the background.
  * When read is called, it immediatly returns the last sampled value.
  *
- * LPC1768 / LPC4088
- * Using more ADC pins in continuous mode will decrease the conversion rate (LPC1768:200kHz/LPC4088:400kHz).
+ * LPC176X / LPC4088
+ * Using more ADC pins in continuous mode will decrease the conversion rate (LPC176X:200kHz/LPC4088:400kHz).
  * If you need to sample one pin very fast and sometimes also need to do AD conversions on another pin,
  * you can disable the continuous conversion on that ADC channel and still read its value.
