Page 5: Introduction
1 INTRODUCTION The PC-CARD-DAC08 is an eight-channel, analog output control board for IBM PC compatible computers having PCMCIA-type slots. The heart of the board is an octal, 13-bit digital-to-analog converter of which only 12 bits are used for each output. -

2 INSTALLATION 2.1 SOFTWARE Your PCM card is completely plug and play. There are no switches or jumpers to set prior to installation in your computer. InstaCal is the installation, calibration and test software supplied with the board. Refer to the Extended Software Installation Manual to install InstaCal. -

CSS is stored in the CB.CBG file by InstaCal. After CSS is installed and a base address has been established, the PC-CARD-DAC08 is controlled by writing to and reading from the control registers. While it is possible to write your own control routines, routines have been written and are available in Universal library for DOS and Windows programming languages. - Page 11 Table 5-1.

Worst case error is realized only in the unlikely event that each of the component errors are at their maximum level, and causing error in the same direction. Each PC-CARD-DAC08 is tested at the factory to ensure the board’s overall SW calibrated error does not exceed ±4.0 LSB. - Page 14 However, this again assumes that each of the errors contributes in the same direction and the ±1.8 LSB specification is quite conservative. Slew Rate ± 1.6 V/µs min Settling Time (to ½ LSB of FSR) 8.0 µs typ Current Drive ±1 mA min Output short-circuit duration Indefinite @15 mA...
