DAC8248FP

The DAC8248FP is a kind of dual 12-bit, double-buffered, CMOS digitalto-analog converter, which 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 designs with a 12-bit or 16-bit wide data path,choose the DAC8222 or DAC8221.

Features of the DAC8248FP are:(1) two matched 12-Bit DACs on one chip;(2) 12-Bit resolution with an 8-Bit data bus;(3) direct interface with 8-Bit microprocessors;(4) double-buffered digital inputs;(5) RESET to zero pin;(6) 12-Bit endpoint linearity (61/2 LSB) over temperature;(7) 15 V to 115 V single supply operation;(8) latch-up resistant;(9) improved ESD resistance;(10) it is available in die form.

The absolute maximum ratings of the DAC8248FP can be summarized as((TA = +25°C unless otherwise noted)):(1): VDD to AGND is 0 V to +17 V;(2): VDD to DGND is 0 V to +17 V;(3): AGND to DGND is 0.3 V to VDD +0.3 V;(4): digital input voltage to DGND is 0.3 V to VDD +0.3 V; (5): VREF A, VREF B to AGND is ±25 V;(6): IOUT A, IOUT B to AGND is 0.3 V to VDD +0.3 V;(7): VRFB A, VRFB B to AGND is ±25 V.
