Maxim MAX543BCSA

Current - UnbufferedSPI5V，11.4V ~ 15.75V0°C ~ 70°C

Overview

The MAX543BCSA is a 12-bit, current-output, multiplying digital-to-analog converter (DAC) that comes in space-saving 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 (μPs) with a serial port, the MAX543BCSA 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 MAX543BCSA is in use. Serial interfacing also reduces the complexity of opto- or transformer-isolated applications. The MAX543BCSA 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 active-low LOAD input low. The MAX 543 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 MAX543BCSA uses low-tempco thin-film resistors laser trimmed to ± LSB linearity and better than ±1 LSB gain accuracy. The digital inputs are protected against electrostatic discharge (ESD) damage and can typically withstand over 5,000V of ESD voltages
