MAX5480

19-1300; Rev 0; 10/97 8-Bit Parallel DAC in QSOP-16 Package _______________General Description The MAX5480 is a CMOS, 8-bit digital-to-analog converter (DAC) that interfaces directly with most microprocessors. On-chip input latches make the DAC load cycle interface similar to a RAM write cycle, where CS and WR are the only control inputs required. Linearity of ±1/2LSB is guaranteed, and power consumption is less than 500µW. Monotonicity is guaranteed over the full operating temperature range. The MAX5480 can be operated in either voltage-output or current-output mode. It is available in a small 16-pin QSOP package. ____________________________Features o QSOP-16 Package (same footprint as SO-8) o Single +5V Supply Operation o VOUT or IOUT Operation o 8-Bit Parallel Interface o Guaranteed Monotonic Over Temperature o Low Power Consumption—100µA max o ±1/2LSB Linearity Over Temperature MAX5480 ________________________Applications Digitally Adjusted Power Supplies Programmable Gain Automatic Test Equipment Portable, Battery-Powered Instruments VCO Frequency Control RF Transmit Control in Portable Radios ______________Ordering Information PART MAX5480ACEE MAX5480BCEE MAX5480AEEE MAX5480BEEE TEMP.
