APPLICATIONS Industrial automation Automatic test equipment Process control Data acquisition systems General-purpose instrumentation GENERAL DESCRIPTION readback allows the user to read the contents of the DAC The AD5570 is a single 16-bit serial input, voltage output DAC register via the SDO pin. that operates from supply voltages of 11.4 V up to 16.5 V. Integral linearity (INL) and differential nonlinearity (DNL) are Features on the AD5570 include LDAC which is used to update accurate to 1 LSB. During power-up, when the supply voltages the output of the DAC. The device also has a power-down pin are changing, V is clamped to 0 V via a low impedance path. OUT ( ), allowing the DAC to be put into a low power state, and a PD The AD5570 DAC comes complete with a set of reference CLR pin that allows the output to be cleared to 0 V. buffers. The reference buffers allow a single, positive reference The AD5570 is available in a 16-lead SSOP. to be used. The voltage on REFIN is gained up and inverted internally to give the positive and negative reference for the PRODUCT HIGHLIGHTS DAC core. Having the reference buffers on-chip eliminates the 1. 1 LSB maximum INL and DNL. need for external components such as inverters, precision 2.
