... DACs. These DACs are “inverted” R-2R ladder net- works that convert 13-bit digital inputs into equivalent analog output voltages, in proportion to the applied ref- erence voltages. The MAX547 has one reference input (REF_) and one analog-ground input (AGND_) for each pair of DACs. The four REF_ inputs allow different full- ...

... DAC pair is set to all 0s its maximum value with all 1s on both DACs. Output Buffer Amplifiers The MAX547’s voltage outputs are internally buffered by precision gain-of-two amplifiers with a typical slew rate of 3V/µs. With a full-scale transition at its output, 1 the typical settling time to ± ...

... Typical Operating Characteristics for dynamic performance of the DACs and output buffers. Digital Code and Analog Output Voltage The MAX547 uses offset binary coding. A 13-bit twos- complement code can be converted to a 13-bit offset binary code by adding 2 For symmetrical bipolar operation, tie AGND_ to the system ground ...
