DAC7545KU-1

The DAC7545KU-1 is the subpackage of DAC7545. The following is some information about the DAC7545. The DAC7545 is a kind of low-cost CMOS, 12-bit fourquadrant multiplying, digital-to-analog converter with input data latches. The input data is loaded into the DAC as a 12-bit data word. It is available in 20-pin SOIC package. The device is intended for battery or other low power applications because the power dissipation is less than 0.5 mW when used with CMOS logic inputs and VDD=+5V.

There are some features of DAC7545KU-1 as follows. (1)four-quadrant multiplication; (2)low gain TC: 2 ppm/ typ; (3)monotonicity guaranteed over temperature; (4)single 5 V to 15 V supply; (5)TTL/CMOS logic compatible; (6)low output leakage: 10 nA max; (7)low output capacitance: 70 pF max; (8)direct replacement for AD7545, PM-7545.

What comes next is about the absolute maximum ratings of DAC7545KU-1 (Ta=25 unless otherwise noted).(1):VDD to DGND is from 0.3 to +17 V; (2):digital input to DGND is from 0.3 to VDD V; (3):VRFB, VREF, to DGND is ±25 V; (4):VPIN 1 to DGND is from 0.3 to VDD V; (5):AGND to DGND is from 0.3 to VDD V; (6):power dissipation is 450 mW for any package to +75 and derates above +75 by 6mW/. (7):operating temperature is from 40 to +85 for commercial J, K, L, GL; (8):storage temperature is from 65 to +150; (9):lead temperature (soldering, 10s) is +300.
