8 / 14 page  Block Diagram TLH11261 – 15 Pin Description VOUT1(19) The voltage output connections of the VOUT2(1) four DACS These provide output VOUT3(14) voltages in the range 03V – 28V VOUT4(11) VREFOUT(16) The internal voltage reference output The output of the reference is 265V g 2% This pin should be bypassed with a 220 mF capacitor VBIAS1(2) VBIAS1 is connected to the non-inverting VBIAS2(13) inputs of output amplifiers 1 and 2 thereby setting the virtual ground voltage for DAC’s 1 and 2 while VBIAS2 performs this function for DAC’s 3 and 4 The allowed range is 03V – 14V GND(7) The system ground pin Connect to clean ground point DVCC(10) The digital and analog power supply AVCC(17) pins The power supply range of the DAC0854 is 45V – 55V To guarantee accuracy it is required that the AVCC and DVCC pins be bypassed separately with bypass capacitors of 10 mF tantalum in parallel with 01 mF ceramic AU(4) When this pin is taken low all DAC outputs will be asynchronously updated CS must be held high during the update VREF1(18) The voltage reference inputs for the four VREF2(20) DACs The allowed range is 0V – 275V VREF3(15) VREF4(12) CS(3) The Chip Select control input This input is active low CLK(5) The external clock input pin DI(9) The serial data input The data is clocked in LSB first Preceding the data byte are 4 or 6 bits of instructions DO(6) The serial data output The data can be clocked out either MSB or LSB first and on either the positive or negative edge of the clock INT(8) The power interrupt output On an interruption of the power supply this pin goes low Since this pin has an open drain output a 10 kX pull-up resistor must be connected to the supply 8 |
