MAX1452

Low-Cost Precision Sensor

Signal Conditioner

General Description

Beneﬁts and Features

● Single-Chip, Integrated Analog Signal Path Reduces

Design Time and Saves Space in a Complete

Precision Sensor Solution

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 temper-

ature compensation that enables an overall performance

approaching the inherent repeatability of the sensor. The

fully analog signal path introduces no quantization noise

in the output signal while enabling digitally controlled trim-

ming with the integrated 16-bit DACs. Offset and span are

calibrated using 16-bit DACs, allowing sensor products to

be truly interchangeable.

• Provides Ampliﬁcation, Calibration, and

Temperature Compensation

• Fully Analog Signal Path

• 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

• Supports Both Current and Voltage Bridge Excitation

• Fast 150μs Step Response

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 com-

pensation, 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.

• On-Chip Uncommitted Op Amp

● On-Chip Lookup Table Supports Multipoint

Calibration Temperature Correction Improving

System Performance

● Secure-Lock™ Prevents Data Corruption

● Low 2mA Current Consumption Simplifies Power-

Supply Design in 4–20mA Applications

The MAX1452 is packaged for the commercial, industrial,

and automotive temperature ranges in 16-pin SSOP/

TSSOP and 24-pin TQFN packages.
