The circuit consists of an up-down counter with the comparator controlling the direction of the count. The analog output of the DAC is compared with the analog input. If the input is greater than the DAC output signal, the output of the comparator goes high and the counter is caused to count up. The tracking ADC has the advantage of being simple.
Switched capacitor DAC contains a parallel capacitor network. Individual capacitors are connected or disconnected with switches based on the input. The R-2R ladder DAC which is a binary-weighted DAC that uses a repeating cascaded structure of resistor values R and 2R. This improves the precision due to the relative ease of producing equal ...
A delta-encoded or counter-ramp ADC has an up-down counter that feeds a DAC. The input signal and the DAC both go to a comparator. The comparator controls the counter. The circuit uses negative feedback from the comparator to adjust the counter until the DAC's output matches the input signal and number is read from the counter. Delta converters ...
The battery life for the first generation iPod Mini was criticized for its 8 hour duration, [8] similar to the third generation iPod that was available at the time. Apple addressed this problem in the second generation models by increasing the battery life to about 18 hours, at the cost of removing the FireWire and AC adapter cables to avoid ...

On the second-generation iPod Shuffle, USB connectivity is provided via an included piece of hardware which acts as a docking station for the transfer of data and the recharging of the iPod's internal battery through its headphone jack. The second-generation iPod Shuffle was also able to act as a flash drive, just like the first-generation iPod ...
By the mid-2000s and the years after, Apple with its iPod was the best-selling DAP or PMP by a significant margin, with one out of four sold worldwide being an iPod. It was especially dominant in the United States where it had over 70% of sales at different points in time, [ 8 ] is nearest competitor in 2006 being SanDisk . [ 54 ]
