- 8-Pin SO Package
- 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
- Wide Single Supply Range: VCC = 4.75V to 15.75V
- Low Power: ICC Typ = 350µA with 5V Supply
DescriptionThe LTC1257 is a complete single supply, 12-bit voltage output D/A converter (DAC) in an SO-8 package. 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 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 12-bit D/A system available.
