Introduction

CMOS multiplying digital-to-analog converters (MDACs) make versatile building blocks that go beyond their basic function of converting digital data into analog signals. This design note details some of the other circuits that are possible when using the LTC1590 dual, serial 12-bit current output DAC. This DAC, shown in Figure 364.1 features:
