The LTC2704-16/LTC2704-14/LTC2704-12 are serial
input, 12-, 14- or 16-bit, voltage output SoftSpan DACs
that operate from 3V to 5V logic and ±5V to ±15V analog
supplies. SoftSpan 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 commands allow verication of any on-chip
register in just one 24- or 32- bit instruction cycle. All other
commands produce a “rolling readback” response from
the LTC2704, dramatically reducing the needed number
of instruction cycles.
A Sleep command allows any combination of DACs to be
powered down. There is also a reset ag and an offset
adjustment pin for each channel.
