LTC1257CS8#TRPBF

LTC1257 is a complete single supply, 12bit voltage output D/A converter (DAC) in a SO-8 package. The LTC1257 includes an output buffer amplifier, 2.048V voltage reference and an easy to use 3-wire cascadable serial interface. An external reference can be used to override the internal reference and extend the output voltage range to 12V. The power supply current is a low 350µA when operating from a 5V supply, making the LTC1257 ideal for battery-powered applications. The space-saving 8-pin SO package and operation with no external components provide the smallest 12bit D/A system available. Applications include digital offset/gain adjustment, industrial process control and automatic test equipment.

• Buffered voltage output, built-in 2.048V reference
• 500µV/LSB with 2.048V full scale, 1/2LSB max DNL error
• Guaranteed 12bit monotonic
• 3-wire cascadable serial interface
• Wide single supply range VCC from 4.75V to 15.75V
• Low power, ICC typical is 350µA with 5V supply
• Offset error of ±8LSB max (when using internal reference)
• Gain error of 0.5LSB typ, voltage output slew rate of 1.0V/µs minimum (5Kohm in parallel with 100pF)
• 8-lead plastic SO package, 0°C to 70°C temperature range
