GENERAL DESCRIPTION
FEATURES
o Provides Amplification, Calibration, and Temperature Compensation o Accommodates Sensor Output Sensitivities from 1mV/V to 40mV/V o Single Pin Digital Programming o No External Trim Components Required o 16-Bit Offset and Span Calibration Resolution o Fully Analog Signal Path o On-Chip Lookup Table Supports Multipoint Calibration Temperature Correction o Supports Both Current and Voltage Bridge Excitation o Fast 3.2kHz Frequency Response o On-Chip Uncommitted Op Amp o Secure-Lock™ Prevents Data Corruption o Low 2mA Current Consumption MAX1452 Offset and span are calibrated using 16-bit DACs, allowing sensor products to be truly interchangeable. The MAX1452 architecture includes a programmable sensor excitation, a 16-step programmable-gain amplifier (PGA), a 768-byte (6144 bits) internal EEPROM, four 16-bit DACs, an uncommitted op amp, and an onchip temperature sensor. In addition to offset and span compensation. The MAX1452 provides a unique temperature compensation strategy for offset TC and FSOTC that was developed to provide a remarkable degree of flexibility while minimizing testing costs.
