DAC7725NB/750G4

Digital To Analog Converters Overview

The DAC7725NB/750G4 is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to provide buffered voltage outputs with a settling time of 10 µs and a sampling rate of 100 kS/s per channel. The device operates on dual analog supply voltages ranging from ±14.25 V to ±15.75 V and a single 5 V digital supply. It features parallel data interfaces and is housed in a 28-pin PLCC package. Key accuracy specifications include a maximum integral nonlinearity (INL) of ±2 LSB and differential nonlinearity (DNL) of ±1 LSB.

Digital To Analog Converters Feature Summary
