♦ Buffered Voltage Outputs
The MAX500 is a quad, 8-bit, voltage-output digital-to-
analog converter (DAC) with a cascadable serial inter-
face. The IC includes four output buffer amplifiers and
input logic for an easy-to-use, two- or three-wire serial
interface. In a system with several MAX500s, only one
serial data line is required to load all the DACs by cas-
cading them. The MAX500 contains double-buffered
logic and a 10-bit shift register that allows all four DACs
to be updated simultaneously using one control signal.
There are three reference inputs so the range of two of
the DACs can be independently set while the other two
DACs track each other.
♦ Double-Buffered Digital Inputs
♦ Microprocessor and TTL/CMOS Compatible
♦ Requires No External Adjustments
♦ Two- or Three-Wire Cascadable Serial Interface
♦ 16-Pin DIP/SO Package and 20-Pin LCC
♦ Operates from Single or Dual Supplies
The MAX500 achieves 8-bit performance over the full
operating temperature range without external trimming.
