LTC2602/LTC2612/LTC2622

Dual 16-/14-/12-Bit

Rail-to-Rail DACs in 8-Lead MSOP

FEATURES

DESCRIPTIO

The LTC^®2602/LTC2612/LTC2622 are dual 16-,14- and

12-bit, 2.5V-to-5.5Vrail-to-railvoltage-outputDACs, ina

tiny 8-lead MSOP package. They have built-in high per-

formance output buffers and are guaranteed monotonic.

■

Smallest Pin-Compatible Dual DACs:

LTC2602: 16-Bits

LTC2612: 14-Bits

LTC2622: 12-Bits

■

Guaranteed 16-Bit Monotonic Over Temperature

These parts establish advanced performance standards

for output drive, crosstalk and load regulation in single-

supply, voltage output multiples.

■

Wide 2.5V to 5.5V Supply Range

■

Low Power Operation: 300µA per DAC at 3V

■

Individual Channel Power-Down to 1µA, Max

■

The parts use a simple SPI/MICROWIRE™ compatible

3-wire serial interface which can be operated at clock

rates up to 50MHz.

Ultralow Crosstalk between DACs (30µV)

■

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

■

Double-Buffered Data Latches

■

Pin-Compatible 10-Bit Version (LTC1661)

The LTC2602/LTC2612/LTC2622 incorporate a power-

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

rise less than 10mV above zero scale, and after power-

up, they stay at zero scale until a valid write and update

take place.
