AD7124-8

[SpeedPIC32]

Hello, I have a new 24-bit AD converter that also has a constant current source up to 1mA.
The whole thing is on the ADC6 click board.
This allows you to measure temperatures with a PT100, for example.

FEATURES
► 3 power modes
► RMS noise
► Low power: 24 nV rms at 1.17 SPS, gain = 128 (255 µA
typical)
► Mid power: 20 nV rms at 2.34 SPS, gain = 128 (355 µA
typical)
► Full power: 23 nV rms at 9.4 SPS, gain = 128 (930 µA typical)
► Up to 22 noise free bits in all power modes (gain = 1)
► Output data rate
► Full power: 9.38 SPS to 19,200 SPS
► Mid power: 2.34 SPS to 4800 SPS
► Low power: 1.17 SPS to 2400 SPS
► Rail-to-rail analog inputs for gains > 1
► Simultaneous 50 Hz/60 Hz rejection at 25 SPS (single cycle
settling)
► Diagnostic functions (which aid safe integrity level (SIL) certification)
► Crosspoint multiplexed analog inputs
► 8 differential/15 pseudo differential inputs
► Programmable gain (1 to 128)
► Band gap reference with 10 ppm/°C drift maximum (70 µA)
► Matched programmable excitation currents
► Internal clock oscillator
► On-chip bias voltage generator
► Low-side power switch
► General-purpose outputs
► Multiple filter options
► Internal temperature sensor
► Self and system calibration
► Sensor burnout detection
► Automatic channel sequencer
► Per channel configuration
► Power supply: 2.7 V to 3.6 V and ±1.8 V
► Independent interface power supply
► Power-down current: 5 µA maximum
► Temperature range: −40°C to +125°C
► 32-lead LFCSP
► 3-wire or 4-wire serial interface
► SPI, QSPI™, MICROWIRE™, and DSP compatible
► Schmitt trigger on SCLK
► ESD: 4 kV
► AEC-Q100 qualified for automotive applications
APPLICATIONS
► Temperature measurement
► Pressure measurement
► Industrial process control
► Instrumentation
► Smart transmitters

Thank you very much.

Hello,

Thanks for the suggestion. I've had a quick look and it looks fairly involved so it's maybe not something we can pump out quickly and cover everything but something basic to get this going looks doable.

I'll get it on the list
