The MAX5865 ultra-low-power, highly integrated analog front end is ideal for portable communication equipment such as handsets, PDAs, WLAN, and 3G wireless terminals. The MAX5865 integrates dual 8-bit receive ADCs and dual 10-bit transmit DACs while providing the highest dynamic performance at ultra-low power. The ADCs' analog I-Q input amplifiers are fully differential and accept 1VP-P full-scale signals. Typical I-Q channel phase matching is ±0.2° and amplitude matching is ±0.05dB. The ADCs feature 48.4dB SINAD and 70dBc spurious-free dynamic range (SFDR) at fIN = 5.5MHz and fCLK = 40MHz. The DACs' analog I-Q outputs are fully differential with ±400mV full-scale output, and 1.4V common-mode level. Typical I-Q channel phase matching is ±0.15° and gain matching is ±0.05dB. The DACs also feature dual 10-bit resolution with 72dBc SFDR, and 57dB SNR at fOUT = 2.2MHz and fCLK = 40MHz.

The ADCs and DACs operate simultaneously or independently for frequency-division duplex (FDD) and time-division duplex (TDD) modes. A 3-wire serial interface controls power-down and transceiver modes of operation. The typical operating power is 75.6mW at fCLK = 40Msps with the ADCs and DACs operating simultaneously in transceiver mode. The MAX5865 features an internal 1.024V voltage reference that is stable over the entire operating power-supply range and temperature range. The MAX5865 operates on a +2.7V to +3.3V analog power supply and a +1.8V to +3.3V digital I/O power supply for logic compatibility. The quiescent current is 8.5mA in idle mode and 1µA in shutdown mode. The MAX5865 is specified for the extended (-40°C to +85°C) temperature range and is available in a 48-pin thin QFN package.

Product Details

The MAX586x evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of this family of analog front ends (AFEs’) that integrate a dual-channel analog-to-digital converter (ADC), a dual-channel digital-to- analog converter (DAC), and a 1.024V internal voltage reference. The EV kit board accepts AC- or DC-coupled, differential or single-ended analog inputs for the receive ADC and includes circuitry that converts the transmit DAC differential output signals to single-ended analog outputs. The EV kit includes circuitry that generates a clock signal from an AC sine wave input signal. The EV kit operates from a +3.0V analog power supply, +3.0V digital power supply, and ±5V bipolar power supply.

The EV kit comes with Windows® 7/10-compatible software that provides a simple graphical user interface (GUI) for exercising the programmable features of the MAX5863–MAX5866.
