Analog Devices AD7190 Manuals

AD7190 is a high precision, low noise, 24-bit sigma-delta ADC with programmable gain amplifier from Analog Devices. It can operate at output data rates from 4.7Hz to 4.8kHz.

The AD7190 is a 4.8 kHz ultralow noise 24-bit Sigma-Delta ADC with PGA. The device offers ultralow noise of 8.5 nV RMS at 4.7 Hz (gain = 128), 16 noise free bits at 2.4 kHz (gain = 128), and up to 22.5 noise free bits (gain = 1). It provides two differential/four pseudo differential input channels, automatic channel sequencer, programmable gain (1 to 128), four general-purpose digital outputs, 3-wire serial SPI, QSPI™, MICROWIRE™, and DSP compatible Schmitt trigger on SCLK, and simultaneous 50 Hz/60 Hz rejection.
