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.

Features
♦ +2.7V to +3.3V Single-Supply Operation
♦ Wide Spurious-Free Dynamic Range: 70dB at fOUT = 2.2MHz
♦ Fully Differential Outputs for Each DAC
♦ ±0.5% FSR Gain Mismatch
♦ ±0.15° Phase Mismatch
♦ Low-Current Standby or Full Shutdown Modes
♦ Internal +1.2V, Low-Noise Bandgap Reference
♦ Small 28-Pin QSOP Package

Applications
