7 / 10 page 3.3V, 16-Bit, 200Msps High Dynamic Performance DAC with CMOS Inputs _______________________________________________________________________________________ 7 Pin Description PIN NAME FUNCTION 1 B1 Data Bit 1 2 B0 Data Bit 0 (LSB) 3XOR XOR Input Pin. XOR = 1 inverts the digital input data. XOR = 0 leaves the digital input data unchanged. XOR has an internal pulldown resistor and may be left unconnected if not used. 4, 9 VCLK Clock Supply Voltage. Accepts a supply voltage range of 3.135V to 3.465V. Bypass each pin with a 0.1µF capacitor to the nearest CLKGND. 5, 8 CLKGND Clock Ground 6 CLKP Converter Clock Input. Positive input terminal for the converter clock. 7 CLKN Complementary Converter Clock Input. Negative input terminal for the converter clock. 10 PD Power-Down Input. PD pulled high enables the DAC’s power-down mode. PD pulled low allows for normal operation of the DAC. 11, 21, 23 AVDD Analog Supply Voltage. Accepts a supply voltage range of 3.135V to 3.465V. Bypass each pin with a 0.1µF capacitor to the nearest AGND. 12, 17, 20, 22, 24, EP AGND Analog Ground. Exposed paddle (EP) must be connected to AGND. 13 REFIO Reference I/O. Output of the internal 1.2V precision bandgap reference. Bypass with a 0.1µF capacitor to AGND. Can be driven with an external reference source. 14 FSADJ Full-Scale Adjust Input. This input sets the full-scale output current of the DAC. For 20mA full-scale output current, connect a 2k Ω resistor between FSADJ and DACREF. 15 DACREF Return Path for the Current Set Resistor. For 20mA full-scale output current, connect a 2k Ω resistor between FSADJ and DACREF. 16, 25, 26, 27, 28, 29 N.C. No connection. Do not connect to these pins. Do not tie these pins together. 18 IOUTN Complementary DAC Output. Negative terminal for differential current output. The full-scale output current range can be set from 2mA to 20mA. 19 IOUTP DAC Output. Positive terminal for differential current output. The full-scale output current range can be set from 2mA to 20mA. 30 SEL0 Mode Select Input SEL0. This pin has an internal pulldown resistor; it can be left open to disable the segment-shuffling function (see the Segment Shuffling section). 31, 43 DVDD Digital Supply Voltage. Accepts a supply voltage range of 3.135V to 3.465V. Bypass each pin with a 0.1µF capacitor to the nearest DGND. 32, 42 DGND Digital Ground 33 B15 Data Bit 15 (MSB) 34 B14 Data Bit 14 35 B13 Data Bit 13 36 B12 Data Bit 12 37 B11 Data Bit 11 |
