●Product Details
●The DAC-8248 is a dual 12-bit, double-buffered, CMOS digital-to-analog converter. It has an 8-bit wide input data port that interfaces directly with 8-bit microprocessors. It loads a 12-bit word in two bytes using a single control; it can accept either a least significant byte or most significant byte first. For designers with a 12-bit or 16-bit wide data path, choose the DAC-8222 or DAC-8221.
●The DAC-8248"s double-buffered digital inputs allow both DAC"s analog output to be updated simultaneously. This is particularly useful in multiple DAC systems where a common LDAC signal updates all DACs at the same time. A single RESET pin resets both outputs to zero.
●The DAC-8248"s monolithic construction offers excellent DAC-to-DAC matching and tracking over the full operating temperature range. The DAC consists of two thin-film R-2R resistor ladder networks, two 12-bit, two 8-bit, and two 4-bit data registers, and control logic circuitry. Separate reference input and feedback resistors are provided for each DAC. The DAC8248 operates on a single supply from +5 V to +15 V, and it dissipates less than 0.5 mW at +5 V (using zero or VDD logic levels). The device is packaged in a space-saving 0.3", 24-pin DIP.
●The DAC-8248 is manufactured with PMI"s highly-stable thin-film resistors on an advanced oxide-isolated, silicon-gate, CMOS technology. PMI"s improved latch-up resistant design eliminates the need for external protective Schoottky diodes.
