Digitally Programmable Sensor Signal Amplifier with EMI Filters

 

 

Description:

 

The AD8556 is a zero-drift, sensor signal amplifier with digitally programmable gain and output offset. Designed to easily and accurately convert variable pressure sensor and strain bridge outputs to a well-defined output voltage range, the AD8556 accurately amplifies many other differential or single-ended sensor outputs. The AD8556 uses the Analog Devices, Inc. patented low noise, auto-zero and DigiTrim® technologies to create an incredibly accurate and flexible signal processing solution in a very compact footprint.

Gain is digitally programmable in a wide range from 70 to 1280 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. The AD8556 also features internal EMI filters on the VNEG, VPOS, FILT and VCLAMP pins.

In addition to extremely low input offset voltage, low input offset

voltage drift, and very high dc and ac CMRR, the AD8556 also

includes a pull-up current source at the input pins and a pulldown current source at the VCLAMP pin, which allows open

wire and shorted wire fault detection. A low-pass filter function

is implemented via a single low cost external capacitor. Output

clamping set via an external reference voltage allows the AD8556

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. Output offset voltage can be adjusted with a

resolution of better than 0.4% of the difference between VDD

and VSS. A lockout trim after gain and offset adjustment further

ensures field reliability.

The AD8556 is fully specified from −40°C to +140°C.

Operating from single-supply voltages of 4.5 V to 5.5 V, the

AD8556 is offered in the 8-lead SOIC_N and 4 mm × 4 mm 16-lead LFCSP_VQ.
