LTC2609/LTC2619/LTC2629

Quad 16-/14-/12-Bit

Rail-to-Rail DACs with

I²C Interface

DESCRIPTIO

FEATURES

The LTC^®2609/LTC2619/LTC2629 are quad 16-, 14- and

12-bit, 2.7V-to-5.5V rail-to-rail voltage output DACs in a

16-lead SSOP package. They have built-in high perfor-

mance output buffers and are guaranteed monotonic.

■

Smallest Pin-Compatible Quad DACs:

LTC2609: 16 Bits

LTC2619: 14 Bits

LTC2629: 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

LTC2609/LTC2619/LTC2629 operate in both the standard

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

of 400kHz).

■

Separate Reference Inputs

■

27 Selectable Addresses

400kHz I²C^™Interface

■

Wide 2.7V to 5.5V Supply Range

■

Low Power Operation: 250µA per DAC at 3V

■

Individual Channel Power Down to 1µA (Max)

■

High Rail-to-Rail Output Drive (±15mA, Min)

■

Ultralow Crosstalk Between DACs (5µV)

■

LTC2609/LTC2619/LTC2629: Power-On Reset to

The LTC2609/LTC2619/LTC2629 incorporate a power-on

reset circuit. During power-up, the voltage outputs rise

lessthan10mVabovezeroscale;afterpower-up,theystay

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

power-on reset circuit resets the LTC2609-1/LTC2619-1/

LTC2629-1 to midscale. The voltage outputs stay at

midscale until a valid write and update take place.
