The LTC2606/LTC2616/LTC2626 are 16-/14-/12-bit rail-to-rail voltage output DACs with I2C interface. They have built-in high-performance output buffers and are guaranteed monotonic. 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. The parts use a 2-wire, I2C compatible serial interface. The LTC2606/LTC2616/LTC2626 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. The LTC2606/LTC2616/LTC2626 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. The power-on reset circuit resets the LTC2606-1/LTC2616-1/LTC2626-1 to midscale. The voltage outputs stay at midscale until a valid write and update take place.
The Linear Technology LTC2606/LTC2616/LTC2626 are single 16-, 14-, and 12-bit, 2.7V-to-5.5V rail-to-rail voltage output DACs in a 10-lead DFN package. These devices feature built-in high-performance output buffers and are guaranteed monotonic over temperature.
The parts utilize a 2-wire, I2C compatible serial interface supporting both standard mode (100kHz) and fast mode (400kHz). They include an asynchronous DAC update pin (LDAC) and a power-on reset circuit that initializes the output to zero scale or midscale depending on the specific part suffix.
