DESCRIPTION

The DAC7545 is a low-cost, CMOS, 12-bit, four-quadrant

multiplying, digital-to-analog converter (DAC) with input data

latches. The input data is loaded into the DAC as a 12-bit

data word. The data flows through to the DAC when both the

Laser-trimmed thin-film resistors and excellent CMOS volt-

age switches provide true 12-bit integral and differential

linearity. The device operates on a single +5V to +15V supply

and is available in an SO-20 package; devices are specified

over the commercial temperature range.

The DAC7545 is well suited for battery-powered or other low-

power applications because the power dissipation is less than

12-Bit
