MAX5186, MAX5189 Dual, 8-Bit, 40MHz, Current/Voltage, Simultaneous-Output DACsThe 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 1A (max) shutdown current. A fast wake-up time (0.5s) 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 (-40C to +85C) temperature range. For higher resolution, dual 10-bit versions, refer to the MAX5180 MAX5183 data sheet. By Maxim Integrated Products |
