11.7 PGA and ADC

Table 11-10. PL460 PGA and ADC Input Characteristics
Parameter	Typical Value	Unit
VIN input impedance	10	kΩ
VIN max voltage dynamic range	± 0.75	V

Note: Although the maximum VIN range is 0 - 3.3V, the PGA has been designed to saturate with any input value greater than the input common mode voltage (VREFC) ± 0.75V. To clamp the input signal, a pair of series diodes can be used to easily achieve it.
