Description
19-1581; Rev 0; 12/99 Dual, 8-Bit, 40MHz, Current/Voltage, Simultaneous-Output DACs General Description 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 10pVs 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. Features o +2.7V to +3.3V Single-Supply Operation o Wi...
