MAX5306/MAX5307 19-2132 Rev 0 8/01 Low-Power, Low-Glitch, Octal 12-Bit Voltage- Output DACs with Serial Interface General Description Features The MAX5306/MAX5307 are 12-bit, eight channel, low- Eight Highly Integrated 12-Bit DACs in power, voltage-output, digital-to-analog converters 16-Pin TSSOP (6.4mm x 5mm) Package (DACs) in a space-saving 16-pin TSSOP package. The Ultra-Low Glitch Energy < 2nV/s wide +2.7V to +5.5V supply voltage range and less than 215A (max) supply current per DAC are excellent Low Total Supply Current: for low-power and low-voltage applications. The low 1.7mA (max) with V = V = +5.5V REF DD 2nV/s glitch energy of the MAX5306/MAX5307 makes +2.7V to +5.5V Wide Single-Supply Range them ideal for digital control of fast-response, closed- loop systems. Fast 5s Settling Time The MAX5306 has a digital output (DOUT) that can be Software-Selectable Shutdown Mode < 1A used for daisy-chaining multiple devices. The MAX5307 has a hardware reset input (CLR) which clears all regis- 15MHz 3-Wire SPI, QSPI, and MICROWIRE- ters and DACs to zero. The MAX5306/MAX5307 have a Compatible Serial Interface software shutdown feature that reduces the supply cur- Power-Up Reset to Zero Scale rent to 1A. The MAX5306/MAX5307 feature a load DAC (LDAC) function that updates the output of all eight DACs simultaneously. The 3-wire SPI, QSPI, MICROWIRE and DSP- compatible serial interface allows the input and DAC registers to be updated independently or simultaneous- ly with a single software command. These devices use Ordering Information a double-buffered design to minimize the digital-noise feedthrough from the digital inputs to the outputs. PART TEMP.
