  • Product introduction

It is a high-precision PGA280 with digitally-controllable instrumentation amplifier gain and signal integrity detection capability.The device offers low bias voltage bias and gain drift, meaning the whole sentence, good linearity, virtually no 1/f noise signal and superior common-mode and supply rejection to support high-resolution accurate measurements.When supply capacity and extensive use of lighting and electrical equipment, the device moves to universal signal measurements with high impedance input ranges that meet the requirements.

Prevents large inrush current multiplexing (MUX) switching from special circuits.In addition, the input switch matrix enables easy refactoring and system-level representation of diagnostics-overload conditions.

The configuration of general-purpose input/output (GPIO) provides several different control and communication features.

characteristic

  • Wide 15.5V Input Range: ±18V supplied in ±
  • Steps for binary gain: 128V to 1/8V/V/V)
  • Additional scale factors: 1V/V and 13/8V/V
  • At low offset voltage: 3μV G = one hundred and twenty-eight
  • The long-term drift of the entire sentence is offset voltage
  • The meaning of the whole sentence is 0.5ppm gain drift: /°C
  • Good linearity of 1.5ppm:
  • 140dB excellent thus:
  • High input impedance
  • Very low 1/f noise
  • Differential signal output
  • Overload detection
  • Enter the configuration switch matrix
  • Broken wire test current
  • Extend SPI and checksum
  • Universal I/O ports
  • TSSOP-24 packaging
