The MAX5713/MAX5714/MAX5715 4-channel, low-power,8-/10-/12-bit, voltage-output Digital-to-analog converters(DACs) include output buffers and an internal referencethat is selectable to be 2.048V, 2.500V, or 4.096V. TheMAX5713/MAX5714/MAX5715 accept a wide supplyvoltage range of 2.7V to 5.5V with extremely low power(3mW) consumption to accommodate most low-voltageapplications. A precision external reference input allowsrail-to-rail operation and presents a 100kI (typ) load toan external reference.
Abstract: This tutorial discusses methods for digitally adjusting the output voltage of a DC-DC converter. The digital adjustmentmethods are with a Digital-to-analog converter (DAC), a trim pot (digital potentiometer), and PWM output of a microprocessor.Each method is assessed and several DACs and digital potentiometers presented.
Abstract: This article discusses application circuits for Maxim force/sense Digital-to-analog converters (DACs). Applications include:selectable fixed-gain DAC, programmable gain DAC, photodiode bias control, amperometric sensor control, digitally programmablecurrent source, Kelvin load sensing, temperature sensing, and high current DAC output. A brief description of the various DAC outputconfigurations is also given.
Digital-to-analog converters (DACs) are prevalent inindustrial control and automated test applications.General-purpose automated test equipment often requiresmany channels of precisely controlled voltagesthat span several voltage ranges. The LTC2704 is ahighly integrated 16-bit, 4-channel DAC for high-endapplications. It has a wide range of features designed toincrease performance and simplify design.
This paper presents the key circuits of a 1MHz bandwidth, 750kb/s GMSK transmitter. The fractional-N synthesizer forming the basis of the transmitter uses a combined phasefrequency
detector (PFD) and Digital-to-analog converter (DAC) circuit element to obtain >28dB high frequency noise reduction when compared to classicalfrequency synthesis.

The MAX5302 combines a low-power, voltage-output,
12-bit Digital-to-analog converter (DAC) and a precision
output amplifier in an 8-pin μMAX package. It operates
from a single +5V supply, drawing less than 280μA of
supply current.
