The MAX2870 ultra-wideband phase-locked loop (PLL) and voltagecontrol oscillator (VCO) can operate in both integer-N and fractional-Nmodes, similar to the Analog Devices ADF4350 wideband synthesizer.This application note compares the MAX2870 and ADF4350 registers andloop filter design in detail. Users who already familiar with ADF4350 canuse this application note as a quick design reference.

Maxim Analog Essentials are a series of plug-in peripheral modules that allow engineers to quickly test, evaluate, and integrate Maxim components into their hardware/software designs. The modules electrically and physically conform to the Digilent Pmod™ interface specification and are compatible with any Digilent Pmod-compatible header.

The MAX4968/MAX4968A are 16-channel, high-linearity,high-voltage, bidirectional SPST analog switches with18I (typ) on-resistance. The devices are ideal for use inapplications requiring high-voltage switching controlledby a low-voltage control signal, such as ultrasound imagingand printers. The MAX4968A provides integrated40kI (typ) bleed resistors on each switch terminal todischarge capacitive loads. Using HVCMOS technology,these switches combine high-voltage bilateral MOSswitches and low-power CMOS logic to provide efficientcontrol of high-voltage analog signals.

The purpose of this application note is to show an example of how a digital potentiometer can be used in thefeedback loop of a step-up DC-DC converter to provide calibration and/or adjustment of the output voltage.The example circuit uses a MAX5025 step-up DC-DC converter (capable of generating up to 36V,120mWmax) in conjunction with a DS1845, 256 position, NV digital potentiometer. For this example, the desiredoutput voltage is 32V, which is generated from an input supply of 5V. The output voltage can be adjusted in35mV increments (near 32V) and span a range wide enough to account for resistance, potentiometer and DCDCconverter tolerances (27.6V to 36.7V).

Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and data-acquisition systems. The analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failure, optocoupler failure, or undervoltage condition occurs. A simple application is shown on how to implement thisfunction.

High input impedance and a wide input range are twohighly desirable features in a precision analog-to-digitalconverter, and the LTC®2449 delta-sigma ADC has both.With just a few external components, the LTC2449 formsan exceptional measurement system with very high inputimpedance and an input range that extends 300mV beyondthe supply rails.

Designers of signal receiver systems often need to performcascaded chain analysis of system performancefrom the antenna all the way to the ADC. Noise is a criticalparameter in the chain analysis because it limits theoverall sensitivity of the receiver. An application’s noiserequirement has a signifi cant infl uence on the systemtopology, since the choice of topology strives to optimizethe overall signal-to-noise ratio, dynamic range andseveral other parameters. One problem in noise calculationsis translating between the various units used by thecomponents in the chain: namely the RF, IF/baseband,and digital (ADC) sections of the circuit.
