DAC 8-CH 10-bit 16-Pin TSSOP

The MAX5308/MAX5309 are 10-bit, eight channel, low-power, voltage-output, digital-to-analog converters (DACs) in a space-saving 16-pin TSSOP package. The wide +2.7V to +5.5V supply voltage range and less than 215µA (max) supply current per DAC are excellent for low-power and low-voltage applications. The low 2nV-s glitch energy of the MAX5308/MAX5309 makes them ideal for digital control of fast-response, closed-loop systems. The MAX5308 has a digital output (DOUT) that can be used for daisy-chaining multiple devices. The MAX5309 has a hardware reset input (active-low CLR) which clears all registers and DACs to zero. The MAX5308/MAX5309 have a software shutdown feature that reduces the supply current to 1µA. The MAX5308/MAX5309 feature a load DAC (active-low 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 simultaneously with a single software command. These devices use a double-buffered design to minimize the digital-noise feedthrough from the digital inputs to the outputs. The MAX5308/MAX5309 operating temperature range is from -40°C to +85°C.
