Digital to Analog

S/PDIF is an acronym for Sony /Philips Digital Interface (or Sony /Philips Digital Interconnect Format). The full specification for the S/PDIF interface consists of hardware and software, but only the hardware side will be discussed here - the software is looked after by the various interface ICs. The hardware interface is the physical connection medium that is used to send data between any two devices...

The 8-bit multiplying DAC-08 is a versatile device that offers excellent performance at low cost. This DAC produces an output current that is the product of an 8-bit digital number and the input reference current. Either a unipolar voltage source for normal D/A conversion or a bipolar signal voltage for multiplying D/A conversion produces this reference current...

LVDTs (linear variable differential transformers) are electromechanical measuring devices that convert the position of a magnetic core into electrical signals. You generate these signals via excitation on the primary side. The results on the secondary sidetypically, two secondary windingsdepend on the position of the core (Figure 1)...

A voltage-output DAC normally generates an output voltage that is a fraction of the input-reference voltage. In many designs, however, it is necessary to multiply the input voltage by a programmable gain, or, in other words, to create a variable-gain stage...
