GENERAL DESCRIPTION

The AD8555 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

AD8555 also accurately amplifies many other differential or

single-ended sensor outputs. The AD8555 uses the ADI

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 1,280

through a serial data interface. Gain adjustment can be fully

simulated in-circuit and then permanently programmed with

proven and reliable poly-fuse technology. Output offset voltage

is also digitally programmable and is ratiometric to the supply voltage.

In addition to extremely low input offset voltage and input

offset voltage drift and very high dc and ac CMRR, the AD8555

also includes a pull-up current source at the input pins and a

pull-down current source at the VCLAMP pin. This 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

AD8555 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 AD8555 is fully specified over the extended industrial

temperature range of −40°C to +125°C. Operating from singlesupply

voltages of 2.7 V to 5.5 V, the AD8555 is offered in the

narrow 8-lead SOIC package and the 4 mm × 4 mm 16-lead LFCSP.
