Rainbow-electronics MAX5159 Manual do Utilizador

_______________General DescriptionThe MAX5158/MAX5159 low-power, serial, voltage-output, dual, 10-bit digital-to-analog converters (DACs)consume only

MAX5158/MAX5159remains active. Data in the input registers is saved,allowing the MAX5158/MAX5159 to recall the outputstate prior to entering shutdown

The MAX5158/MAX5159’s digital inputs are doublebuffered, which allows any of the following: loading theinput register(s) without updating the DAC regi

Serial-Data OutputThe serial-data output, DOUT, is the internal shift regis-ter’s output. DOUT allows for daisy chaining of devicesand data readback.

MAX5158/MAX5159produce a range of 0V to 2.5V with a 1.25V reference.Table 2 lists the unipolar output codes. An offset to theoutput can be achieved by
