instrumentation amp recommendations for PIC

Using a PIC, we have to count some pulses from a HALL effect device and
measure some strain guages.

Any recommendations on a single voltage supply instrumentation amplifier
that we could use for both functions?

Both functions? The Hall device will probably have a digital output
and can go (more or less) directly into a digital PIC input. At most
you'd need a crude comparator with some hysteresis (perhaps the
built-in crude comparator which some PICs have).

Strain gauges require energization and usually some kind of
amplification before the typical on-board ADC, but the type of signal
conditioning required is very much dependent on the output voltage of
the sensor and required accuracy and stability. A silicon strain gauge
pressure sensor will probably be *much* less demanding than a metal
strain gauge load cell.
