MAX509ACWP+

The MAX509ACWP+ is a quad, serial 8bit digital to analogue (DAC) with rail to rail outputs in 20 pin WSOIC package. It has four separate reference inputs allowing DAC's full-scale range to be set independently. Device communicates with microprocessors through a synchronous, full-duplex, 3-wire interface. Data is sent MSB first and can be transmitted in one 4-bit and one 8bit packet or in one 12-bit word. If a 16-bit control word is used, the first four bits are ignored. A 4-wire interface adds a line for LDAC and allows asynchronous updating. The serial clock (SCLK) synchronizes the data transfer. Data is transmitted and received simultaneously. The interface is compatible with MICROWIRE and SPI/QSPI. All digital inputs and outputs are TTL/CMOS compatible. A buffered data output provides for readback or daisy-chaining of serial devices.

• Supply voltage range is 4.5V to 5.5V, -5.5V to 0V
• Operating temperature range from 0°C to +70°C
• Output buffer amplifier swing rail to rail
• Reference input range includes both supply rails
• Calibrated offset, gain and linearity (1LSB TUE)
• 10MHz serial interface, compatible with SPI, QSPI (CPOL = CPHA = 0) and MICROWIRE
• Double buffered registers for synchronous updating
• Serial data output for daisy-chaining
• Power-on reset clears serial interface and sets all registers to zero
