The LTC1257 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 350 µA 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 12-bit D/A system available. s 8-Pin SO Package s Buffered Voltage Output s Built-In 2.048V Reference s 500 µV/LSB with 2.048V Full Scale s 1/2LSB Max DNL Error s Guaranteed 12-Bit Monotonic s 3-Wire Cascadable Serial Interface s Wide Single Supply Range: VCC = 4.75V to 15.75V s Low Power: ICC Typ = 350µA with 5V Supply , LTC and LT are registered trademarks of Linear Technology Corporation. µP 5V 0.1 µF 0.1 µF CONTROL OUTPUT 1 CONTROL OUTPUT 2 VCC VREF GND VOUT DIN CLK LOAD DOUT LTC1257 VCC VREF GND VOUT DIN CLK LOAD DOUT LTC1257 TO NEXT DAC 1257 TA01 Daisy-Chained Control Outputs FEATURES DESCRIPTIO APPLICATIO S TYPICAL APPLICATIO |
