8-Bit Parallel DAC in QSOP-16 Package

Single, Parallel, Current-Output DAC in a QSOP Package

Viewing:

Overview

  • QSOP-16 Package (same footprint as SO-8)
  • Single +5V Supply Operation
  • VOUT or IOUT Operation
  • 8-Bit Parallel Interface
  • Guaranteed Monotonic Over Temperature
  • Low Power Consumption-100µA max
  • ±1/2 LSB Linearity Over Temperature

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 active-low CS and active-low WR are the only control inputs required.

Linearity of ±1/2 LSB is guaranteed, and power consumption is less than 500 µW. 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.

Applications

  • Digitally Adjusted Power Supplies
  • General Purpose
  • Portable Battery-Powered Instruments
  • Programmable Gain
  • RF Transmit Control in Portable Radios
  • VCO Frequency Control
