The AT90PWM81 features a 10-bit successive approximation ADC. The ADC is connected to an 15-
channel Analog Multiplexer which allows eleven single-ended input. The single-ended voltage inputs
refer to 0V (GND).
The device also supports 2 differential voltage input combinations which are equipped with a programma-
ble gain stage, providing amplification steps of 14dB (5x), 20 dB (10x), 26 dB (20x), or 32dB (40x) on the
differential input voltage before the A/D conversion. On the amplified channels, 8-bit resolution can be
expected.
The ADC contains a Sample and Hold circuit which ensures that the input voltage to the ADC is held at a
constant level during conversion. A block diagram of the ADC is shown in
The ADC has a separate analog supply voltage pin, AV
V
Internal reference voltages of nominally 2.56V or AV
be externally decoupled at the AREF pin by a capacitor for better noise performance.
