8-bit, 40mhz, Current/voltage-output Dacs

The MAX5187 is an 8-bit, current-output digital-to-ana- log converter (DAC) designed for superior performance in signal reconstruction or arbitrary waveform genera- tion applications requiring Analog signal reconstruction with low distortion and low-power operation. The volt- age-output MAX5190 provides equal specifications, with on-chip precision resistors for voltage output oper- ation. Both devices are designed for a 10pVs glitch operation to minimize unwanted spurious signal com- ponents at the output. An on-board +1.2V bandgap cir- cuit provides a well-regulated, low-noise reference that CAN be disabled for external reference operation. The MAX5187 MAX5190 are designed to provide a high level of signal integrity for the least amount of power dissipation. They operate from a single supply of +2.7V to +3.3V. Additionally, these DACs have three modes of operation: normal, low-power standby, and full shut- down, which provides the lowest possible power dissi- pation with a 1A (max) shutdown current. A fast wake-up time (0.5s) from standby mode to full DAC operation allows for power conservation by activating the DAC only when required. The MAX5187 MAX5190 are packaged in a 24-pin QSOP and are specified for the extended (-40C to +85C) temperature range. For higher resolution, 10-bit versions, see the MAX5181 MAX5184 data sheet.
