SP9601DS/02 SP9601 12-Bit, Low-Power Voltage Output © Copyright 2000 Sipex Corporation SP9601 12–Bit, Low Power Voltage Output D/A Converter n Low Power — 2mW n Voltage Output, 4.5V range n Midscale Preset, Zero Volts Out n 250KHz Multiplying Bandwidth (4-Quadrant) n Standard 3-Wire Serial Interface n 8–pin (0.15") SOIC and Plastic DIP Packages n ±5V supply operation DESCRIPTION… The SP9601 is a very low power 12-Bit Digital-to-Analog Converter. It features ±4.5V output swings when using ±5 volt supplies. The converter uses a standard 3–wire serial interface compatible with SPI™ , QSPI™ and Microwire™ . The output settling-time is specified at 30µs. The SP9601 is available in 8–pin 0.15" SOIC and DIP packages, specified over commercial and industrial temperature ranges.

Integral Linearity, for the SP9601 , is measured as the arithmetic mean value of the magnitudes of the greatest positive deviation and the greatest negative deviation from the theoretical value for any given input condition. 2. Differential Linearity is the deviation of an output step from the theoretical value of 1 LSB for any two adjacent digital input codes. 3. 1 LSB = 2*V REF /4,096. 4. V REF = 0V. 5. The following power up sequence is recommended: VSS (-5V), Vdd (+5V), VREF .
