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.
FOUR-QUADRANT MULTIPLICATION
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
DIRECT REPLACEMENT FOR THE AD7545,
PM-7545
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.
