MAX5186:双路、8位、40MHz、电流/电压、同时输出DAC

The MAX5186 contains two 8-bit, simultaneous-update, current-output digital-to-analog converters (DACs) designed for superior performance in communications systems requiring analog signal reconstruction with low distortion and low-power operation. The MAX5189 provides equal specifications, with on-chip precision resistors for voltage output operation. The MAX5186/ MAX5189 are designed for a 10pV-s glitch operation to minimize unwanted spurious signal components at the output. An on-board 1.2V bandgap circuit provides a well-regulated, low-noise reference that can be disabled for external reference operation. The MAX5186/MAX5189 are designed to provide a high level of signal integrity for the least amount of power dissipation. Both DACs operate from a single supply voltage of 2.7V to 3.3V. Additionally, these DACs have three modes of operation: normal, low-power standby, and complete shutdown, which provides the lowest possible power dissipation with a 1µA (max) shutdown current. A fast wake-up time (0.5µs) from standby mode to full DAC operation allows power conservation by activating the DACs only when required. The MAX5186/MAX5189 are packaged in a 28-pin QSOP and are specified for the extended (-40°C to +85°C) temperature range. For higher resolution, dual 10-bit versions, refer to the MAX5180/MAX5183 data sheet.
