Product Overview

The LTC1257CS8#PBF is a complete single-supply 12-bit voltage output D/A Converter includes an output buffer amplifier, 2.048V voltage reference and an easy to use three-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. An internal NMOS transistor with a 200R equivalent impedance pulls the output to ground. The output is protected against short-circuits and is able to drive up to a 500pF capacitive load without oscillation. The DAC register loads the data from the shift register when LOAD is pulled low and remains transparent until LOAD is pulled high and the data is latched.
  • Buffered voltage output
  • Built-in 2.048V reference
  • 500µV/LSB with 2.048V full scale
  • 1/2 LSB max DNL error
  • Guaranteed 12-bit monotonic
  • Three-wire cascadable serial interface
  • Low power (ICC Typical = 350µA with 5V supply)
