RangeRite ADC – High-Resolution Dynamic Range Measurement Platform

Why the high precision low power RangeRite ADC family Rocks

--> Wide selection of unipolar (0 to 5.12V, 6.144V, 10.24V, 12.288V) and bipolar (+/- 2.56V, +/- 5.12V, +/- 6.144V, +/- 10.24V, +/- 12.288V) input ranges – easily configured right in firmware. Go from small-signal precision to large-swing dynamics with zero hassle.

--> High precision options at 16-bit or 18-bit resolutions combined with the input range settings provides the ultimate high resolution flexibility

--> Highly integrated measurement solution: includes Front end ADC buffer, anti-aliasing filtering (15kHz BW), and a precision voltage reference are all built-in to a small low power form factor

--> With 100 kSPS or 500 kSPS max sample rate options, RangeRite is fast enough for capturing dynamic AC signals

--> Flexible power options allows RangeRite to run off a wide input supply (6V–18V) with an optional digital supply rail to match your system logic (1.8V to 5V).

--> Clean power = clean measurements: Dual-stage noise filtering keeps supply ripple and noise where it belongs – out of your data.

--> Low-power performance: Consumes only about 5 mA max with a small 51mm x 22mm form factor, making RangeRite perfect for portable battery-powered and remote applications where.

The RangeRite ADC family is controlled and ADC data read back using a standard SPI communication interface:
--> Uses SPI mode 0 with data read back MSB first
--> Max SPI clock rate: 66.67MHz

Firmware selectable input voltage ranges, note that ADC measurements are automatically scaled to the set voltage input range:
--> Unipolar ranges: 0V to 5.12V, 6.144V, 10.24V, 12.288V
--> Bipolar ranges: +/- 2.56V, +/- 5.12V, +/- 6.144V, +/- 10.24V, +/- 12.288V

DC measurement accuracy specifications, giving in least significant bits (LSB) and % of reading:
--> 18 bit versions: 3.10 LSB or 0.01 %
--> 16 bit versions: 0.81 LSB or 0.01%

Dynamic signal measurement accuracy giving in effective number of bits (ENOB):
--> ENOB @ ~1 kHz for all versions: ~15 bits

Includes built-in anti-aliasing low pass filter with cutoff frequency of ~15kHz. Filter cutoff frequency is the same for both maximum sample rate versions 100kSPS and 500kSPS

Max current draw for powering the RangeRite: 5mA which includes both analog and digital power.
--> Main power input (Vin): 6V to 18V
--> Optional digital power input, which sets digital logic voltage level (VDIG): 1.8V to 5V

Form factor: 51mm x 22mm with 2.54mm pin spacing. Mounting holes have a diameter of 3mm
