description

The LTC®2609 / LTC2619 / LTC2629 are four-channel 16, 14, and 12-bit, 2.7V to 5.5V rail-to-rail output DACs in a 16-pin SSOP package. They have built-in high-performance output buffers and guarantee monotony. These devices set new board density benchmarks for 16- and 14-bit DACs and raise the bar for output drive and load regulation performance in single-supply, voltage-output DACs. The devices feature a two-wire, I2C-compatible serial interface. LTC2609 / LTC2619 / LTC2629 operates in standard mode (100kHz clock rate) and fast mode (400kHz clock rate). LTC2609 / LTC2619 / LTC2629 has a built-in power-on reset circuit. During power-up, the voltage output rises to less than 10mV above the zero scale; After powering up, they remain at zero scale until a valid write and update operation appears. The power-on reset circuit resets LTC2609-1 / LTC2619-1 / LTC2629-1 to the intermediate scale. The voltage output remains on the intermediate scale until a valid write and update operation occurs
