LTC2704
Quad 12-, 14- and 16-Bit Voltage Output SoftSpan
DACs with Readback
DESCRIPTION
The LTC®2704-16/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 verification 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 flag and an offset adjustment pin for each channel.
