... Programmable Voltage and Current Sources Programmable Attenuators GENERAL DESCRIPTION The AD5300 is a single, 8-bit buffered voltage out DAC that operates from a single +2 +5.5 V supply consuming 115 Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5300 utilizes a versatile three-wire serial interface that operates at clock rates MHz and is compatible with standard SPI™ ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD5300 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... Hex) is loaded to the DAC register. Ideally the output should The zero-code error is always positive in the AD5300 because the output of the DAC cannot go below due to a combination of the offset errors in the DAC and output amplifier. Zero-code error is expressed in LSBs. A plot of zero-code error vs ...

... AD5300 GENERAL DESCRIPTION D/A Section The AD5300 DAC is fabricated on a CMOS process. The archi- tecture consists of a string DAC followed by an output buffer amplifier. Since there is no reference input pin, the power supply (V ) acts as the reference. Figure 20 shows a block DD diagram of the DAC architecture. ...

The ADSP-2101/ADSP-2103 should be set up to operate in the SPORT Transmit Alternate Framing Mode. The ADSP-2101/ADSP-2103 SPORT is programmed through the SPORT control register and should be configured as follows: Internal Clock Operation, Active Low Framing, 16- Bit Word Length ...

... AD5300. If the low AD5300* dropout REF195 is used, the current it needs to supply to the SYNC AD5300 is 140 A. This is with no load on the output of the DAC. When the DAC output is loaded, the REF195 also needs to SCLK supply the current to the load. The total current required (with ...

... The printed circuit board containing the AD5300 should have separate analog and digital sections, each having its own area of the board. If the AD5300 system where other devices require an AGND to DGND connection, the connec- tion should be made at one point only. This ground point should be as close as possible to the AD5300 ...
