LTC2637IDE-LZ8#PBF

LTC2637 is an octal 8bit voltage-output DAC with an integrated, high-accuracy, low-drift 10ppm/°C reference. It has a rail-to-rail output buffer and is guaranteed monotonic. It has a full-scale output of 2.5V and operates from a single 2.7V to 5.5V supply. Each DAC can also operate with an external reference, which sets the DAC full-scale output to the external reference voltage. These DACs communicate via a 2-wire I²C-compatible serial interface. It operates in both the standard mode (clock rate of 100KHz) and the fast mode (clock rate of 400KHz). It incorporates a power-on reset circuit. Options are available for reset to zero-scale or reset to mid-scale in internal reference mode, or reset to mid-scale in external reference mode after power-up.

• Internal reference voltage is 2.5V
• Power on reset to code is zero-scale
• Power on reference mode is internal
• VCC is 2.7V to 5.5V
• Maximum INL is ±0.5LSB
• Supply current is 0.8mA typical at (VCC = 3V, VREF =2.5V, external reference)
• Settling time is 3.5µs typical at (±0.39% (±1LSB at 8bits)
• Output voltage noise is 35µVP-P typical at (0.1Hz to 10Hz, external reference)
• Operating temperature is -40°C to 85°C (industrial)
• Package style is 14-lead DFN
