ANALOG DEVICES LTC1456IS8#PBF Digital to Analogue Converter, Rail-to-Rail Output, 12 bit, 3 Wire, Serial, 4.5V to 5.5V, NSOIC

LTC1456IS8#PBF is a complete single supply, rail-to-rail voltage output, 12bit digital-to-analogue converter (DAC). It includes a rail-to-rail output buffer amplifier and an easy-to-use 3-wire cascadable serial interface. It includes an active-low CLR pin that asynchronously clears the DAC to zero scale. The LTC1456 has an internal 2.048V reference and a full-scale output of 4.095V. It operates on a 4.5V to 5.5V supply, dissipating 2.2mW. Applications include digital calibration, industrial process control, automatic test equipment, and cellular telephones.

• 12bit resolution, buffered true rail-to-rail voltage output
• Asynchronous clear input, built-in reference
• Schmitt trigger on clock input allows direct optocoupler interface
• Power-on reset clears DAC to 0V, 3-wire cascadable serial interface
• Integral nonlinearity is ±3.5LSB maximum at (VCC = 4.5V to 5.5V, TA = 25°C)
• Offset error is ±12mV maximum at (VCC = 4.5V to 5.5V, TA = 25°C)
• Positive supply voltage range from 4.5V to 5.5V, supply current is 430µA typ at (TA = 25°C)
• Offset error temperature coefficient is ±15µV/°C typical at (VCC = 4.5V to 5.5V, TA = 25°C)
• Voltage output slew rate is 1V/µs typical at (VCC = 4.5V to 5.5V, TA = 25°C)
• Operating temperature range from -40°C to 85°C, 8-lead plastic SO package
