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 ...
iPod Hi-Fi is a discontinued speaker system that was developed and manufactured by Apple Inc. and was released on February 28, 2006, for use with any iPod digital music player. [1] The iPod Hi-Fi retailed at the Apple Store for US$ 349 until its discontinuation on September 5, 2007.
Figure 2: 4-bit linear R–2R DAC using unequal resistors. It is not necessary that each "rung" of the R–2R ladder use the same resistor values. It is only necessary that the "2R" value matches the sum of the "R" value plus the Thévenin-equivalent resistance of the lower-significance rungs. Figure 2 shows a linear 4-bit DAC with unequal ...
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 ...
Delta-sigma (ΔΣ; or sigma-delta, ΣΔ) modulation is an oversampling method for encoding signals into low bit depth digital signals at a very high sample-frequency as part of the process of delta-sigma analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).
Sometimes adapters are needed, in which case an external breakout box can be used. DAQ cards often contain multiple components (multiplexer, ADC, DAC, TTL-IO, high-speed timers, RAM). These are accessible via a bus by a microcontroller, which can run small programs. A controller is more flexible than a hard-wired logic, yet cheaper than a CPU ...
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.
