The Series has 16-bit binary resolution with ±0.003% integral nonlinearity. These units are self-contained, including a low-tempco Zener reference circuit and an output amplifier, in a miniature 24-pin DDIP package. circuit. This eliminates code dependent ground currents by routing currents from the positive supply to the internal ground node as determined by the R-2R ladder network. The internal feedback resistors for the on-board amplifier track the ladder network resistors, enhancing temperature stability and performance. The excellent tracking of the resistors results in tempcos for differential nonlinearity, gain and zero of ±2, ±15 and ±5ppm/°C max., respectively. The DAC-HP Series offers both unipolar and bipolar modes with outputs of 0 to +10V and ±5V respectively. Devices with a bipolar output range of ±10V are also available and are designated with a "-1" suffix after the model designation. Input coding is complementary binary and complementary offset binary. The DAC-HP Series operates off of ±15V supplies and offers models with temperature performance covering the 0 to +70°C commercial or –55 to +125°C military temperature ranges. High reliability MIL-STD-883 versions are also available. The DAC-HP design incorporates thin and thickfilm hybrid technology. The design also includes an on-board amplifier and a precision Zener reference BLOCK DIAGRAM BIPOLAR OFFSET 18 +15V SUPPLY 23 –15V SUPPLY 19 GROUND 20 17 OUTPUT 6.4kΩ REFERENCE 24 OUT 5kΩ 5kΩ 6.4V REFERENCE GAIN ADJUST 22 REFERENCE CONTROL CIRCUIT 21 SUMMING JUNCTION • www.datel.com 16-BIT D/A CONVERTER BITS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 MSB LSB DIGITAL INPUTS Figure 1.

It is recommended that these converters be operated with local supply bypass capacitors of 1mF (tantalum type) at the +15V and –15V supply pins. The capacitors should be connected as close to the pins as possible. In highfrequency noise environments, an additional 0.01mF ceramic capacitor should be used in parallel with each tantalum bypass. ±0.0045% of FSR 14 bits ±0.1% ±0.15% of FSR ±15ppm/°C of FSR ±20ppm/°C of FSR ±5ppm/°C of FSR ±8ppm/°C of FSR ±2ppm/°C of FSR 15 μs ±20V/ s ±0.003%FSR/% ➄ 2. When laying out the circuit board for this device, isolate the analog, digital and power grounds as much as possible from each other before joining them at pin 20. 3. If the reference output (pin 24) is used, it must be buffered by an operational amplifier in the noninverting mode. See Figure 2. Current drawn from pin 24 should be limited to ±10mA in order that the temperature coefficient of the reference circuit not be affected. This is sufficient current for the bias current requirements of most popular operational amplifier types. 0 to +10V ±5V ±10V ±5mA 0.05 CALIBRATION PROCEDURE +15V, ±0.5V at 20mA –15V, ±0.5V at 25mA ±12V operation ➇ 0°C to +70°C (BMC, BGC, BMC-C, BGC-C) –40°C to +100°C (BME, BGE, BME-C, BGE-C) –55°C to +125°C (BMM, 883, BMM-C, -C/883) –65°C to +150°C 24-pin DDIP 0.22 ounces (6.3 grams) For bipolar operation, connect Bipolar Offset (pin 18) to Summing Junction (pin 21). For unipolar operation, connect Bipolar Offset (pin 18) to Ground (pin 20). In making the following adjustments, refer to the Coding Tables and Connection Diagrams. 1. Zero Adjustment. Set the input digital code to 1111 1111 1111 1111 and adjust the ZERO ADJ. potentiometer to give 0.00000V output for unipolar operation or –FS output for bipolar operation. 2. Gain Adjustment. Set the input digital code to 0000 0000 0000 0000 and adjust the GAIN ADJ. potentiometer to give +FS – 1LSB output for either unipolar or bipolar operation. Footnotes: * MAXIMUM OUTPUT CURRENT IS ±10μA ➀ Drive from TTL output with only the DAC-HP as load. ➁ FSR is full-scale range and is 10V for 0 to +10V or –5V to +5V outputs, 20V for ±10V output, etc. ➂ For all models except DAC-HP16BGC. ➃ Settling to ±0.5mV. ➄ ±0.006%FSR/% maximum over full military temperature range for MM and 883 models. ➅ Unipolar output range for suffix “–1” models, 0 to +10V, is reached at the 1/2 scale point. ➆ Pin 17. ➇ For ±12V operation, consult factory.
