MX7543KCWE+

The MX7543KCWE+ is a CMOS, 12bit, serial-input DAC in 16 pin WSOIC package. The MX7543 is a high precision 12-bit digital to analogue converter (DAC) which uses a serial rather than parallel input scheme for loading data. Included are a serial to parallel shift register, a separate DAC register and a multiplying DAC. Serial data is clocked in at the SRI pin on the rising or failing edge (user selected) of the strobe input. When the input register is full, the contents are transferred to the DAC register using the load input. A clear input is provided to initialize the part asynchronously. The MX7543 features excellent gain stability and operates from a single +5V power supply while dissipating about 10mW. Typical applications include remote analogue systems, robotics, programmable attenuators, ATE and auto-calibration systems.

• Supply voltage range from 4.75V to 5.25V

• 5ppm/°C gain stability
• 1LSB maximum feedthrough at 10KHz
• Gain error is ±12.3LSB
• Supply current is 2.5mA
• Operating temperature range from 0°C to 70°C
