MAX5308/MAX5309 19-2151 Rev 0 8/01 Low-Power, Low-Glitch, Octal 10-Bit Voltage- Output DACs with Serial Interface General Description Features The MAX5308/MAX5309 are 10-bit, eight channel, low- Eight Highly Integrated 10-Bit DACs in 16-Pin power, voltage-output, digital-to-analog converters (DACs) TSSOP (6.4mm 5mm) Package in a space-saving 16-pin TSSOP package. The wide Ultra-Low Glitch Energy <2nV-s +2.7V to +5.5V supply voltage range and less than 215A (max) supply current per DAC are excellent for low-power Low Total Supply Current: and low-voltage applications. The low 2nV-s glitch energy 1.7mA (max) with V = V = +5.5V REF DD of the MAX5308/MAX5309 makes them ideal for digital +2.7V to +5.5V Wide Single-Supply Range control of fast-response, closed-loop systems. The MAX5308 has a digital output (DOUT) that can be Fast 5s Settling Time used for daisy-chaining multiple devices. The MAX5309 Software-Selectable Shutdown Mode < 1A has a hardware reset input (CLR) which clears all regis- ters and DACs to zero. The MAX5308/MAX5309 have a 15MHz 3-Wire SPI, QSPI, and MICROWIRE- software shutdown feature that reduces the supply cur- Compatible Serial Interface rent to 1A. The MAX5308/MAX5309 feature a load Power-Up Reset to Zero Scale 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- Ordering Information ly with a single software command. These devices use a double-buffered design to minimize the digital-noise PART TEMP. RANGE PIN-PACKAGE feedthrough from the digital inputs to the outputs. MAX5308EUE -40C to +85C 16 TSSOP The MAX5308/MAX5309 operating temperature range MAX5309EUE -40C to +85C 16 TSSOP is from -40C to +85C.
