LTC2753 OPERATION Output Ranges The LTC2753 is a dual current-output, parallel-input preci- sion multiplying DAC with software-programmable output ranges. SoftSpan provides two unipolar output ranges ( and 0V to 10V), and four bipolar ranges (±2.5V, ±5V, ±10V and ...
Page 15
OPERATION These devices also have a power-on reset that initializes both DACs any output range. The DACs OUT power up in the 0V-5V range if the part is in SoftSpan confi guration; for manual span ...

LTC2753 OPERATION System Offset Adjustment Many systems require compensation for overall system offset. The R and R offset adjustment pins are VOSA VOSB provided for this purpose. For noise immunity and ease of adjustment, the control voltage is attenuated to ...
Page 17
OPERATION—EXAMPLES 1. Load ±5V range with the output at 0V. Note that since span and code are updated together, the output, if started at 0V, will stay there. The 16-Bit DAC code is shown in hex for compactness. WR SPAN ...

LTC2753 APPLICATIONS INFORMATION Op Amp Selection Because of the extremely high accuracy of the 16-bit LTC2753-16, careful thought should be given to op amp selection in order to achieve the exceptional performance of which the part is capable. Fortunately, the ...
Page 19
APPLICATIONS INFORMATION Op amp offset will contribute mostly to output offset and gain error, and has minimal effect on INL and DNL. For example, for the LTC2753-16 with a 5V reference in 5V unipolar mode, a 250μV op amp offset ...
