LTC1592 - 具可编程输出范围的 16 位 SoftSpan DAC

The LTC®1588/LTC1589/LTC1592 are serial input 12-/14-/16-bit multiplying current output DACs that operates from a single 5V supply. These SoftSpan™ 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.

INL and DNL are accurate to 1LSB over the industrial temperature range in both unipolar and bipolar modes. True 16-bit 4-quadrant multiplication is achieved with on-chip four quadrant multiplication resistors. The LTC1588/LTC1589/LTC1592 are available in a 16-lead SSOP package.

These devices include an internal deglitcher circuit that reduces the glitch impulse to less than 2nV-s (typ).

The asynchronous clear pin resets the LTC1588/LTC1589/ LTC1592 to 0V in unipolar or bipolar mode.
