Product Overview

The AD8557ARZ is a Digitally Programmable Sensor Signal Amplifier designed to easily and accurately convert variable pressure sensor and strain bridge outputs to a well-defined output voltage range. It uses patented low noise auto-zero and DigiTrim® technologies to create an accurate and flexible signal processing solution. Gain is digitally programmable in a wide range from 28 to 1300 through a serial data interface. Gain adjustment can be fully simulated in circuit and then permanently programmed with reliable polyfuse technology. Output offset voltage is also digitally programmable and is ratiometric to the supply voltage. Output clamping set via an external reference voltage allows the amplifier to drive lower voltage ADCs safely and accurately. When used in conjunction with an ADC referenced to the same supply, the system accuracy becomes immune to normal supply voltage variations.
  • 12μV Maximum offset voltage
  • 65nV/°C Maximum offset drift
  • High CMRR
  • Digitally programmable gain and output offset voltage
  • Gain range from 28 to 1300
  • Single-wire serial interface
  • Stable with any capacitive load
ESD sensitive device, take proper precaution while handling the device.
