General Description
The MAX514 contains four 12-bit R-2R multiplying digi-
tal-to-analog converters (DACs), each with a serial-in
parallel-out shift register, a DAC register, and control
logic. The MAX514's 3-wire serial interface design mini-
mizes the number of package pins and internal level
translators, so it uses less board space and dissipates less
power (10mW max) than parallel-interface devices.
When used with microprocessors (pPs) with a serial port,
the MAX514 minimizes digital-noise feedthrough from its
logic input pins to its analog output. To further reduce
noise, the " serial port can be used as a dedicated
analog bus and kept inactive while the MAX514 is in use.
Serial interfacing also simplifies opto-coupler or trans-
former-isolated applications.
This device uses kow-tempco thin-film resistors, lasertrimmed
to :1 LSB linearity, with gain accuracy better than i11/2LSB.
The MAX514 is specified with a +5V power supply. All
logic inputs are TTL and CMOS compatible. It comes in
space-saving 24-pin DIP and 28-pin SO packages.
