LTC2657BIFE-L16#PBF

LTC2657BIFE-L16#PBF is an octal I²C, 16bit, rail-to-rail DAC. The LTC2657-L has a full-scale output of 2.5V with the integrated reference and operates from a single 2.7V to 5.5V supply. The parts use a 2-wire I²C compatible serial interface. The LTC2657 operates in both the standard mode (maximum clock rate of 100KHz) and the fast mode (maximum clock rate of 400KHz). The LTC2657 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs reset to zero-scale at power-up. If PORSEL is tied to VCC, the DACs reset to mid-scale at power-up. Applications include mobile communications, process control and industrial automation, instrumentation, automatic test equipment, and automotive.
