DESCRIPTION

The LTC®1588/LTC1589/LTC1592 are serial input 12-/14-/16-bit multiplying current output DACs that operates from a single 5V supply. These SoftSpanTM DACs can be software-programmed for either unipolar or bipolar mode through a 3-wire SPI interface. In either mode, the voltage output range can also be software-programmed. Two output ranges in unipolar mode and four output ranges in bipolar mode are available.
