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
chip select (CS ) and the write (WR) pins are at a logic low.
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
0.5mW when used with CMOS logic inputs and VDD = +5V.
