The ATtiny25/45/85 features a 10-bit successive approximation Analog to Digital Converter
(ADC). The ADC is connected to a 4-channel Analog Multiplexer which allows one differential
voltage input and four single-ended voltage inputs constructed from the pins of Port B. The dif-
ferential input (PB3, PB4 or PB2, PB5) is equipped with a programmable gain stage, providing
amplification step of 26 dB (20x) on the differential input voltage before the A/D conversion. The
single-ended voltage inputs refer to 0V (GND).
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
on page
Internal voltage references of nominally 1.1V or 2.56V are provided On-chip. The Internal volt-
age reference of 2.56V can optionally be externally decoupled at the AREF (PB0) pin by a
capacitor, for better noise performance. Alternatively, V
single ended channels. There is also an option to use an external voltage reference and turn-off
the internal voltage reference. These options are selected using the REFS[2:0] bits of the
ADMUX control register.
