General Description
The MAX543 is a 12-bit, current-output, multiplying digi-
tal-to-analog converter (DAC) that comes in space-sav-
ing 8-pin DIP and 8- or 16-pin surface-mount SO
packages. Its 3-wire serial interface saves additional
board space and also results in low power dissipation.
When used with microprocessors (pPs) with a serial port,
the MAX543 minimizes the digital noise feedthrough from
its input pins to its output. The serial port can be used
as a dedicated analog bus and kept inactive while the
MAX543 is in use. Serial interfacing also reduces the
complexity of opto- or transformer-isolated applications.
The MAX543 contains a 12-bit R-2R type DAC, a serial-in
parallel-out shift register, a DAC register and control
logic. On the rising edge of the clock (CLK) pulse, the
serial input (SRI) data is shifted into the MAX543. When
all the data is clocked in, it is transferred into the DAC
register by taking the LOAD input low.
The MAX543 is specified with a single power supply of
either +5V or +15V. With a +5V supply, the digital inputs
are TTL and +5V CMOS compatible. High-voltage
CMOS compatibility is maintained with a +15V supply.
Maxim's MAX543 uses low-tempco thin-film resistors
laser trimmed to t1/4LSB linearity and better than tl LSB
gain accuracy. The digital inputs are protected against
electrostatic discharge (ESD) damage and can typically
withstand over 5,000V of ESD voltages.
