The MAX514 contains four 12-bit R-2R multiplying digital-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 minimizes 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 (µPs) with a serial port, the MAX514 minimizes digital-noise feedthrough from its logic input pins to its analog output. To further reduce noise, the µP 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 transformer-isolated applications. This device uses low-tempco thin-film resistors, laser trimmed to ±1 LSB linearity, with gain accuracy better than ±1½ LSB. 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.
