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.
