20-Bit ADC which digital filters

20-Bit ADC which digital filters

CS5526CS5526 are highly integrated A/D converters which include
An instrumentation amplifier, a PGA (programmable gain
amplifier), eight digital filters, and self and system calibration

The converters are designed to provide their own negative
supply which enables their on-chip instrumentation
amplifiers to measure bipolar ground-referenced signals
±100 mV. By directly supplying NBV with -2.5 V and
with VA+ at 5 V, 2.5 V signals (with respect to ground)
can be measured.

- 11.47 Hz to 616 Hz (XIN = 100 kHz)
lOutput Settles in One Conversion Cycle
lSimultaneous 50/60 Hz Noise Rejection
lSystem and Self-Calibration with
Read/Write Registers
lSingle +5 V Analog Supply
+3.0 V or +5 V Digital Supply
lLow Power Mode Consumption: 4 mW
