AD7193:  4-Channel, 4.8 kHz, Ultralow Noise, 24-Bit Sigma-Delta ADC with PGA

Product Details


The AD7193 is designed for the measurement of wide dynamic range, low frequency signals such as those in pressure transducers, strain gauge transducers, flow measurement, chromatography and data acquisition systems etc.

The AD7193 is an low power, flexible, high performance, ultra-low noise, 24 bit, Sigma Delta ADC suitable for converting low input bandwidth analog signals with a fully flexible ODR (output data rate) between 4.7SPS to 4.8kSPS

There is an on-chip low noise gain stage which allows signals of small amplitude to interface directly to the ADC.

The AD7193 combines 4 differential or 8 pseudo differential input channels with low power figures.

With an ODR of 4.7sps and a gain of 128 the AD7193 can boast RMS noise of 11nV.

The AD7193 is user friendly, with full part configuration available over a 3 wire serial interface.

The AD7193 comes in a 28 lead TSSOP package and a 32 lead LFCSP package.

  • Mains power supply interference Simultaneous 50Hz and 60Hz rejection at 50SPS ODR
  • Programmable gains of 1, 8, 16, 32, 64 and 128
  • Automatic channel sequencer
  • On chip temperature sensor
  • Internal and system calibration on chip
  • Option of 4.92MHz internal clock or external crystal
  • Digital filter options include Sinc4 Sinc3 , chop enabled/disabled, fast settling and zero latency
  • Ultra-Low noise figures across the ODR range
  • Fully SPI, QSPI, Microwire and DSP compatible
  • SPI configuration control
  • 3 wire serial digital interface (Schmitt trigger on SCLK)
