Figure 52. Typical Bridge Application
ERROR BUDGET ANALYSIS
To illustrate how instrumentation amplifier specifications are
applied, review a typical case where an AD524 is required to
amplify the output of an unbalanced transducer. Figure 52
shows a differential transducer, unbalanced by 100 Ω, supplying
a 0 mV to 20 mV signal to an AD524C. The output of the IA
feeds a 14-bit ADC with a 0 V to 2 V input voltage range. The
operating temperature range is 25°C to +85°C. Therefore, the
largest change in temperature, ΔT, within the operating range is
from ambient to +85°C (85°C 25°C = 60°C).
Figure 50. Software Controllable Offset
In many applications, complex software algorithms for autozero
applications are not available. For those applications, Figure 51
provides a hardware solution.

In many applications, differential linearity and resolution are of
prime importance in cases where the absolute value of a variable is
less important than changes in value. In these applications, only
the irreducible errors (45 ppm = 0.004%) are significant. Further-
more, if a system has an intelligent processor monitoring the
analog-to-digital output, the addition of an autogain/autozero
cycle removes all reducible errors and may eliminate the require-
ment for initial calibration. This also reduces errors to 0.004%.
