ANALOG DEVICES LTC2641IMS8-12#PBF Digital to Analogue Converter, 12 bit, 3 Wire, Microwire, QSPI, Serial, SPI, 2.7V to 5.5V, MSOP

LTC2641-12 is a 12bit unbuffered voltage output DAC. This DAC operates from a single 2.7V to 5.5V supply and is guaranteed monotonic over temperature. LTC2641 features a reference input range of 2V to VDD. VOUT swings from 0V to VREF. It uses a simple SPI/MICROWIRE compatible 3-wire serial interface which can be operated at clock rates up to 50MHz and can interface directly with optocouplers for applications requiring isolation. A power-on reset circuit clears the LTC2641�s DAC output to zero scale. A logic low on the CLR pin asynchronously clears the DAC to zero scale. Applications includes high resolution offset and gain adjustment, process control and industrial automation, automatic test equipment and data acquisition systems.

• Differential nonlinearity of ±0.5LSB (max), integral nonlinearity of ±0.5LSB max at full temp
• Power supply rejection of ±0.5LSB max at full operating temperature range
• Typical gain error of ±0.5LSB at full operating temperature range
• Maximum 16bit INL error, ±1LSB over temperature
• 2.7V to 5.5V single supply operation, low 120µA supply current
• Unbuffered voltage output directly drives 60K loads
• 50MHz SPI/QSPI/MICROWIRE compatible serial interface
• Schmitt-trigger inputs for direct optocoupler interface
