MAX533BCEE+

The MAX533BCEE+ is a low power, 8bit quad digital to analogue converter (DAC) with rail to rail output buffers in 16 pin QSOP package. This serial input, voltage output DAC operates from a single 2.7V to 3.6V supply. Internal precision buffers swing rail to rail and reference input range includes both ground and positive rail. The serial interface is double buffered. A 12bit input shift register is followed by four 8bit buffer registers and four 8bit DAC registers. The 12bit serial word consists of eight data bits and four control bits (for DAC selection and special programming commands). Two additional asynchronous control pins, active-low LDAC and active-low CLR provide simultaneous updating or clearing of input and DAC registers. The interface is compatible with SPI, QSPI and Microwire. A buffered data output allows daisy chaining of serial devices. The MAX533B is used in digital gain and offset adjustments, programmable attenuators and current sources.

• Asynchronous hardware clear resets all internal registers to zero

• Integral nonlinearity of ±2LSB and differential nonlinearity of ±1LSB (monotonic, all codes)
• Ultra low supply current of 0.68mA while operating and 1μA in shutdown mode
• Ground to VDD reference input range
• Output buffer amplifiers swing rail to rail
• Zero code error of ±20mV and full scale error of ±30mV
• Serial data output for daisy chaining
• Power-on reset clears serial interface and sets all registers to zero
• Software shutdown software programmable logic output
