LTC2634IMSE-LZ12#PBF

LTC2634-L is a family of quad voltage output DAC with an integrated, high accuracy, low drift 10ppm/°C reference. It has rail-to-rail output buffers and is guaranteed monotonic. This 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 full-scale output to the external reference voltage. This DAC communicates via an SPI/MICROWIRE compatible 3-wire serial interface which operates at clock rates up to 50MHz. Serial data output (SDO), a hardware clear (active-low CLR), and an asynchronous DAC update (active-low LDAC) capability are available in the QFN package. This incorporates a power-on reset circuit. Typical applications are mobile communications, process control and industrial automation, automatic test equipment, portable equipment.

• Selectable internal or external reference, double buffered data latches

• ±2.5LSB maximum INL
• Offset error is ±5mV maximum (VCC=3V, internal ref, TA=25°C. VCC=2.7V to 5.5V)
• VOS temperature coefficient is ±10µV/°C typical (VCC=3V, TA=25°C. VCC=2.7V to 5.5V)
• Power supply rejection is –80dB typical (VCC=3V ±10% or 5V ±10%, TA=25°C. VCC=2.7V to 5.5V)
• Output voltage noise is 35µVP-P typical (0.1Hz to 10Hz, TA=25°C. VCC=2.7V to 5.5V)
• 10-lead MSOP package
• Industrial temperature range from -40°C to 85°C
