Overview

  • 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 at fOUT = 2.2MHz
  • ±0.15° Phase Mismatch at fOUT = 2.2MHz
  • Low-Current Standby or Full Shutdown Modes
  • Internal 1.2V, Low-Noise Bandgap Reference
  • Small 28-Pin QSOP Package

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.

Evaluation Kits

MAX5183EVKIT

Evaluation Kit for the MAX5180, MAX5182, MAX5183, MAX5185, MAX5186, MAX5188, MAX5189, and MAX5191

Features and Benefits

  • Fast Evaluation and Performance Testing
  • SMA Coaxial Connectors for Clock and Data Inputs
  • Performance-Optimized Four-Layer PC Board with Separate Analog and Digital Power and Ground Connections
  • On-Board Differential to Single-Ended Conversion Circuitry
  • Fully Assembled and Tested with MAX5183BEEI

Product Details

The MAX5183 evaluation kit (EV kit) is designed to simplify evaluation of the 8-bit and 10-bit, dual, 40MHz, simultaneous-update or alternate-phase-update MAX5180/MAX5183, MAX5182/MAX5185, MAX5186/MAX5189, and MAX5188/MAX5191 digital-to-analog converters (DACs). The board contains all circuitry necessary for evaluating the dynamic performance of these high-speed converters, including a circuit to convert the DAC's differential outputs into single-ended outputs. Since the design combines high-speed analog and digital circuitry, the board layout calls for special precautions and design features.

Connector pads for power supplies (AVDD, DVDD, VCC, and VEE), DAC outputs (VOUT1, VOUT1A, VOUT2, and VOUT2A), and SMA connectors for the digital and control inputs (D0-D9,active-low CS, CLK) simplify connection to the EV kit. The four-layer board layout is optimized for best dynamic performance.

The MAX5183 dual, 10-bit, 40MHz, simultaneous update DAC is installed on the EV kit board. The kit can be used to evaluate the MAX5180, MAX5182, MAX5185, MAX5186, MAX5188, MAX5189, or MAX5191 with minor component changes.
