AD7846KNZ

AD7846 is a 16-bit DAC constructed with the Analog Devices, Inc., LC²MOS process. It has VREF+ and VREF− reference inputs and an on-chip output amplifier. In addition to the excellent accuracy specifications, this device also offers a comprehensive microprocessor interface. There are 16 data I/O pins, plus control lines (CS, R/W, LDAC and CLR). R/W and CS allow writing to and reading from the I/O latch. This is the readback function, which is useful in ATE applications. LDAC allows simultaneous updating of DACs in a multi-DAC system and the CLR line will reset the contents of the DAC latch to 00…000 or 10…000 depending on the state of R/W.
