Datasheet Analog Devices AD7730BRUZ

a Bridge Transducer ADC
AD7730/AD7730L
The modulator output is processed by a low pass programmable
digital filter, allowing adjustment of filter cutoff, output rate and
settling time. KEY FEATURES
Resolution of 230,000 Counts (Peak-to-Peak)
Offset Drift: 5 nV/C
Gain Drift: 2 ppm/C
Line Frequency Rejection: >150 dB
Buffered Differential Inputs
Programmable Filter Cutoffs
Specified for Drift Over Time
Operates with Reference Voltages of 1 V to 5 V The part features two buffered differential programmable gain
analog inputs as well as a differential reference input. The part
operates from a single +5 V supply. It accepts four unipolar
analog input ranges: 0 mV to +10 mV, +20 mV, +40 mV and
+80 mV and four bipolar ranges: ± 10 mV, ± 20 mV, ± 40 mV
and ± 80 mV. The peak-to-peak resolution achievable directly
from the part is 1 in 230,000 counts. An on-chip 6-bit DAC
allows the removal of TARE voltages. Clock signals for synchronizing ac excitation of the bridge are also provided. ADDITIONAL FEATURES
Two-Channel Programmable Gain Front End
On-Chip DAC for Offset/TARE Removal
