DESCRIPTION
The DAC708 and DAC709 are 16-bit converters designed to interface to an 8-bit microprocessor bus. 16bit data is loaded in two successive 8-bit bytes into parallel 8-bit latches before being transferred into the D/A latch. The DAC708 and DAC709 are current and voltage output models respectively and are in 24-pin hermetic DIPs. Input coding is Binary Two's Complement (bipolar) or Unipolar Straight Binary (unipolar, when an external logic inverter is used to invert the MSB). In addition, the DAC708/709 can be loaded serially (MSB first). The DAC707 is designed to interface to a 16-bit bus.
8-Bit (DAC708, 709) or 16-Bit (DAC707) Serial Data Low Byte Latch High Byte Latch D/A Latch Reference Circuit 16-Bit D/A Converter Bipolar Offset
Data is written into a 16-bit latch and subsequently the D/A latch. The DAC707 has bipolar voltage output and input coding is Binary Two's Complement (BTC). All models have Write and Clear control lines as well as input latch enable lines. In addition, DAC708 and DAC709 have Chip Select control lines. In the bipolar mode, the Clear input sets the D/A latch to give zero voltage or current output. They are all 14-bit accurate and are complete with reference, and for the DAC707, and DAC709, a voltage output amplifier. All models are available with an optional burn-in screening.

*Specification same as for models in column to the left. NOTES: (1) MSB must be inverted externally prior to DAC708/709 input. (2) Digital inputs are TTL, LSTTL, 54/74C, 54/74HC and 54/74HTC compatible over the specified temperature range. (3) DAC708 (current-output models) are specified and tested with an external output operational amplifier connected using the internal feedback resistor in all tests. (4) FSR means Full Scale Range. For example, for ±10V output, FSR = 20V. (5) ±0.0015% of Full Scale Range is equal to 1 LSB in 16-bit resolution, ±0.003% of Full Scale Range is equal to 1 LSB in 15-bit resolution. ±0.006% of Full Scale Range is equal to 1 LSB in 14-bit resolution. (6) Error at input code 0000H. (For unipolar connection on DAC708/709, the MSB must be inverted externally prior to D/A input.) (7) Adjustable to zero with external trim potentiometer. Adjusting the gain potentiometer rotates the transfer function around the bipolar zero point. (8) With gain and zero errors adjusted to zero at +25°C. (9) Maximum represents the 3 limit. Not 100% tested for this parameter. (10) The bipolar worst-case code change is FFFFH to 0000H and 0000H to FFFFH. For unipolar (DAC708/709 only) it is 7FFFH to 8000H and 8000H to 7FFFH.

ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
