DAC8426FSZ

Product Summary

The DAC8426FSZ is a complete quad voltage output D/A converter with internal reference. This product fits directly into any existing 7226 socket where the user currently has a 10 V external reference. The external reference is no longer necessary. The internal reference of the DAC8426FSZ is laser-trimmed to ±0.4% FEATURES No Adjustments Required, Total Error 61 LSB Max Over Temperature Four Voltage-Output DACs on a Single Chip Internal 10 V Bandgap Reference Operates from Single 115 V Supply Fast 50 ns Data Load Time, All Temperatures Pin-for-Pin Replacement for PM-7226 and AD7226, Eliminates External Reference APPLICATIONS Process Controls Multichannel Microprocessor Controlled: System Calibration Op Amp Offset and Gain Adjust Level and Threshold Setting offering a 25 ppm/℃ temperature coefficient and 5 mA of external load driving capability. The DAC8426FSZ contains four 8-bit voltage-output CMOS D/A converters on a single chip. A 10 V output bandgap reference sets the output full-scale voltage. The circuit also includes four input latches and interface control logic. One of the four latches, selected by the address inputs, is loaded from the 8-bit data bus input when the write strobe is active low. All digital inputs are TTL/CMOS (5 V) compatible. The on-board amplifiers can drive up to 10 mA from either a single or dual supply. The on-board reference that is always connected to the internal DACs has 5 mA available to drive external devices.
