LTC2607/LTC2617/LTC2627
16-/14-/12-Bit Dual Rail-to-Rail
DACs with I
2
C Interface
The LTC
®
2607/LTC2617/LTC2627 are dual 16-, 14- and
12-bit, 2.7V to 5.5V rail-to-rail voltage output DACs in a
12-lead DFN package. They have built-in high perfor-
mance output buffers and are guaranteed monotonic.
These parts establish new board-density benchmarks for
16- and 14-bit DACs and advance performance standards
for output drive and load regulation in single-supply,
voltage-output DACs.
The parts use a 2-wire, I
