The AD5570 is a single 16-bit serial input, voltage output DACthat operates from supply voltages of ±11.4 V up to ±16.5 V. Integral linearity (INL) and differenTIal nonlinearity (DNL) areaccurate to 1 LSB. During power-up, when the supply voltages are changing, VOUT is clamped to 0 V via a low impedance path.The AD5570 DAC comes complete with a set of referencebuffers. The reference buffers allow a single, posiTIve referenceto be used. The voltage on REFIN is gained up and inverted internally to give the posiTIve and negaTIve reference for the DAC core. Having the reference buffers on-chip eliminates theneed for external components such as inverters, precisionamplifiers, and resistors, thereby reducing the overall solution size and cost.
