Manufacturer:TI Description:The SN54LS51JCSN54LS51J4 are serial-input, voltage-out- put, 16-bit digital-to-analog converters (DACs) in tiny µMAX packages, 50% smaller than comparable DACs in 8-pin SOs. They operate from low +3V (SN54LS51J3/ SN54LS51J4) or +5V (SN54LS51J/SN54LS51J) single sup- plies. They provide 16-bit performance (2LSB INL and 1LSB DNL) over temperature without any adjustments. Unbuffered DAC outputs result in a low supply current of 120µA and a low offset error of 2LSB. The DAC output ranges from 0 to VREF. For bipolar operation, matched scaling resistors are provided in the SN54LS51J/SN54LS51J4 for use with an external preci- sion op amp (such as the MAX400), generating a VREF output swing. A 16-bit serial word is used to load data into the DAC latch. The 25MHz, 3-wire serial interface is compatible with SPI™/QSPI™/MICROWIRE™, and can interface directly with optocouplers for applications requiring isola- tion. A power-on reset circuit clears the DAC output to code 0 (SN54LS51J/SN54LS51J3) or code 32768 (SN54LS51J /SN54LS51J4) when power is initially applied. A logic low on CLR asynchronously clears the DAC out- put to code 0 (SN54LS51J/SN54LS51J3) or code 32768 (SN54LS51J/SN54LS51J4) independent of the serial interface. The SN54LS51J/SN54LS51J3 are available in 8-pin µMAX packages. The SN54LS51J/SN54LS51J4 are available in 10- pin µMAX packages. |
