General Description

The MAX5180 contains two 10-bit, simultaneousupdate, 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 MAX5183 provides equal specifications, with on-chip precision resistors for voltage output operation. The devices are designed for 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

♦ ±0.2° Phase Mismatch

♦ Low-Current Standby or Full-Shutdown Modes

♦ Internal 1.2V Low-Noise Bandgap Reference

♦ Small 28-Pin QSOP Package
