Soft Span offers six output spans- two unipolar and four bipolar- fully programmable through the 3-wire SPI serial interface. INL is accurate to 1LSB (2LSB for the LTC2704-16). DNL is accurate to 1LSB for all versions. Readback mands allow verification of any on-chip register in just one 24- or 32- bit instruction cycle. All other mands produce a “rolling readback” response from the LTC2704, dramatically reducing the needed number of instruction cycles. A Sleep mand allows any bination of DACs to be powered down. There is also a reset flag and an offset adjustment pin for each channel. L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
