MAX1452

General Description

Features

♦ Provides Amplification, Calibration, and

The MAX1452 is a highly integrated analog-sensor sig-

nal processor optimized for industrial and process con-

trol applications utilizing resistive element sensors. The

MAX1452 provides amplification, calibration, and tem-

perature compensation that enables an overall perfor-

mance approaching the inherent repeatability of the

sensor. The fully analog signal path introduces no quan-

tization noise in the output signal while enabling digitally

controlled trimming with the integrated 16-bit DACs.

Offset and span are calibrated using 16-bit DACs,

allowing sensor products to be truly interchangeable.

Temperature Compensation

♦ Accommodates Sensor Output Sensitivities

from 4mV/V to 60mV/V

♦ Single Pin Digital Programming

♦ No External Trim Components Required

♦ 16-Bit Offset and Span Calibration Resolution

♦ Fully Analog Signal Path

♦ On-Chip Lookup Table Supports Multipoint

The MAX1452 architecture includes a programmable

sensor excitation, a 16-step programmable-gain ampli-

fier (PGA), a 768-byte (6144 bits) internal EEPROM,

four 16-bit DACs, an uncommitted op amp, and an on-

chip temperature sensor. In addition to offset and span

compensation, the MAX1452 provides a unique tem-

perature compensation strategy for offset TC and

FSOTC that was developed to provide a remarkable

degree of flexibility while minimizing testing costs.

Calibration Temperature Correction

♦ Supports Both Current and Voltage Bridge

Excitation

♦ Fast 150µs Step Response

♦ On-Chip Uncommitted Op Amp

♦ Secure-Lock™ Prevents Data Corruption

♦ Low 2mA Current Consumption

The MAX1452 is packaged for the commercial, industri-

al, and automotive temperature ranges in 16-pin SSOP/

TSSOP and 24-pin TQFN packages.
