DIGITAL-TO-ANALOG CONVERTER  
Microprocessor Compatible  
FEATURES  
DESCRIPTION  
FOUR-QUADRANT MULTIPLICATION  
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.  
LOW-GAIN TC: 2ppm/°C typ  
MONOTONICITY ENSURED OVER TEMPERATURE  
SINGLE 5V TO 15V SUPPLY  
TTL/CMOS LOGIC COMPATIBLE  
LOW OUTPUT LEAKAGE: 10nA max  
LOW OUTPUT CAPACITANCE: 70pF max  
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.  
DIRECT REPLACEMENT FOR THE AD7545,  
PM-7545  
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.
