MAX5191:双路、8位、40MHz、电流/电压、输出交替更新DAC

The MAX5188 is a dual 8-bit, alternate-phase-update, current-output digital-to-analog converter (DAC) designed for superior performance in systems requiring analog signal reconstruction with low distortion and low-power operation. The MAX5191 provides equal specifications, with on-chip output resistors for voltage-output operation. Both devices are designed for 10pV-s glitch operation to reduce distortion and minimize unwanted spurious signal components at the output. An on-board +1.2V bandgap circuit provides a well-regulated, low-noise reference that may be disabled for external reference operation. The MAX5188/MAX5191 are designed to provide a high level of signal integrity for the least amount of power dissipation. Both DACs operate from a +2.7V to +3.3V single supply. Additionally, these DACs have three modes of operation: normal, low-power standby, and full shutdown. A full shutdown provides the lowest possible power dissipation with a maximum shutdown current of 1µA. A fast wake-up time (0.5µs) from standby mode to full DAC operation allows for power conservation by activating the DACs only when required. The MAX5188/MAX5191 are available in a 28-pin QSOP package and are specified for the extended (-40°C to +85°C) temperature range. For pin-compatible 10-bit versions, refer to the MAX5182/MAX5185 data sheet.
