LTC1450L

The LTC1450 and LTC1450L are complete single supply rail-to-rail voltage output, 12-bit DACs in 24-pin SSOP and PDIP packages. They include an output buffer amplifier, a reference and a double-buffered parallel digital interface. These DACs use a proprietary architecture which guarantees a maximum DNL error of 0.5LSB. A built-in power-on reset ensures that the output of the DAC is initialized to zero ...
