Benefits
• Reduces Bill of Materials (BOM) cost
– High integration minimizes external
components, requires no external trim
components; to produce calibrated and
accurate output
• Removes all systematic errors for a
highly accurate output
– Fully analog signal path provides a
continuous output with no quantization
error
– Four 16-bit DACs (76μV resolution)
provide compensation accuracy of
full-span output (FSO) and offset
– Multitemperature compensation allows
calibration that approaches repeatability
of the input signal
• Reduces product development time and
inventory complexity
– Suitable for use with many types of
transducers and in multiple applications
– Using same signal conditioner in
many applications allows reuse of the
application circuit
– Can be used in products requiring
voltage output or 4–20mA current loop
MAX1452
The MAX1452 is a versatile analog sensor signal conditioner that
accepts output from all types of resistive elements. Its fully analog
signal path enables a fast response and also provides current or
voltage excitation for optimal design flexibility. Four integrated
16-bit DACs and a PGA provide high-resolution input compensation,
amplification, and calibration. The MAX1452 includes on-chip flash
memory and a temperature sensor that performs multitemperature-
point compensation for accurate readings.
Low-cost, high-precision sensor signal conditioner simplifies sensor design
