Analog Ground for DAC E and DAC F
_______________Detailed Description
Analog Section
The MAX547 contains eight 13-bit, voltage-output
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-
scale output voltages for each DAC pair, and the four
AGND_ inputs allow different offset voltages for each
DAC pair.
The DAC ladder outputs are buffered with op amps that
operate with a gain of two. The inverting node of the
amplifier is connected to the respective reference
input, resulting in bipolar output voltages from -REF_ to
4095/4096 REF_. Figure 1 shows the simplified DAC
circuit.
