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 voltage 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 lowpower applications because the power dissipation is less than 0.5mW when used with CMOS logic inputs and VDD = +5V.
