description

The LTC®2605/LTC2615/LTC2625 is an 8-channel 16, 14, and 12-bit, 2.7V to 5.5V rail-to-rail voltage output DAC in a 16-pin narrow-body 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 driver, crosstalk, and load regulation performance in single-supply, multi-voltage output applications. These devices use a two-wire I2C-compatible serial interface. LTC2605/LTC2615/LTC2625 operates in standard mode (maximum clock rate of 100kHz) and fast mode (maximum clock rate of 400kHz). LTC2605/LTC2615/LTC2625 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 LTC2605-1/LTC2615-1/LTC2625-1 to the intermediate scale. The voltage output remains at the intermediate scale until a valid write operation and update occurs
