The ATtiny26(L) features a 10-bit successive approximation ADC. The ADC is connected to an
11-channel Analog Multiplexer which allows eight differential voltage input combinations or 11
single-ended voltage inputs constructed from seven pins from Port A and four pins from Port B.
Seven of the differential inputs are equipped with a programmable gain stage, providing amplifi-
cation steps of 0 dB (1x) and 26 dB (20x) on the differential input voltage before the A/D
conversion. There are four groups of three differential analog input channel selections. All input
channels in each group share a common negative terminal, while another ADC input can be
selected as the positive input terminal. The single-ended voltage inputs refer to 0V (GND).
The ADC contains a Sample and Hold Amplifier 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 Figure 51.
The ADC has an analog supply voltage pin, AVCC. The voltage on AVCC must not differ more
than ±0.3V from V
how to connect these pins.
An internal reference voltage of nominally 2.56V is provided On-chip, and this reference may be
externally decoupled at the AREF pin by a capacitor.
