LTC2607/LTC2617/LTC2627

16-/14-/12-Bit Dual Rail-to-Rail

DACs with I²C Interface

FEATURES

DESCRIPTIO

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.

■

Smallest Pin-Compatible Dual DACs:

LTC2607: 16 Bits

LTC2617: 14 Bits

LTC2627: 12 Bits

■

Guaranteed Monotonic Over Temperature

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.

Thepartsusea2-wire, I²Ccompatibleserialinterface. The

LTC2607/LTC2617/LTC2627 operate in both the standard

mode (clock rate of 100kHz) and the fast mode (clock rate

of 400kHz). An asynchronous DAC update pin (LDAC) is

also included.

than10mVabovezeroscale;andafterpower-up, theystay

at zero scale until a valid write and update take place. The

power-on reset circuit resets the LTC2607-1/LTC2617-1/

LTC2627-1 to midscale. The voltage outputs stay at

midscale until a valid write and update takes place.
