Process control equipment GENERAL DESCRIPTION They can be operated from a wide variety of supply and reference The DAC8412/DAC8413 are quad, 12-bit voltage output voltages with supplies ranging from single +5 V to 15 V, and DACs with readback capability. Built using a complementary references from +2.5 V to 10 V. Power dissipation is less than BiCMOS process, these monolithic DACs offer the user very 330 mW with 15 V supplies and only 60 mW with a +5 V supply. high package density. For MIL-STD-883 applications, contact your local Analog Output voltage swing is set by the two reference inputs V REFH Devices, Inc. sales office for the DAC8412/DAC8413/883 data and V . By setting the V input to 0 V and V to a REFL REFL REFH sheet, which specifies operation over the 55C to +125C positive voltage, the DAC provides a unipolar positive output temperature range. All 883 parts are also available on Standard range. A similar configuration with VREFH at 0 V and VREFL at a Military Drawings 5962-91 76401MXA through 76404M3A. negative voltage provides a unipolar negative output range. 0.500 Bipolar outputs are configured by connecting both VREFH and VREFL to nonzero voltages. This method of setting output voltage 0.375 +125C range has advantages over other bipolar offsetting methods +25C 0.250 because it is not dependent on internal and external resistors with different temperature coefficients. 0.125 Digital controls allow the user to load or read back data from any 0 DAC, load any DAC, and transfer data to all DACs at one time. 55C 0.125 An active low RESET loads all DAC output registers to midscale V = +15V DD for the DAC8412 and zero scale for the DAC8413. 0.250 V = 15V SS V = +10V REFH The DAC8412/DAC8413 are available in 28-lead plastic DIP, 0.375 V = 10V REFL T = 55C, +25C, +125C 28-lead ceramic DIP, 28-lead PLCC, and 28-lead LCC packages.
