MAX1454

Precision Sensor Signal Conditioner

with Overvoltage Protection

General Description

Benefits and Features

The MAX1454 is a highly integrated analog sensor

signal conditioner targeted for automotive applications.

The device provides amplification, calibration, and tem-

perature compensation to enable 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

trimming of the output. Offset and span are calibrated

with integrated 16-bit DACs, allowing sensors to be truly

interchangeable.

S Complete Signal Conditioning in a Single IC

Package

 Provides Amplification, Calibration, and

Temperature Compensation

 Accommodates Sensor Output Sensitivities

from 1mV/V to 200mV/V

 Overvoltage Protection to 45V

 Reverse-Voltage Protection to 45V

S High-Precision Compensation Reduces

Downstream Circuit Complexity

The device architecture includes a programmable sen-

sor excitation, a 32-step programmable-gain amplifier

(PGA), a 2K x 8 bits internal flash memory, four 16-bit

DACs, and an on-chip temperature sensor. In addition

to offset and span compensation, the device provides a

unique temperature-compensation method for offset TC

and FSO TC to provide a remarkable degree of flexibility

while minimizing manufacturing costs.

 Fully Analog Signal Path

 16-Bit Offset and Span-Calibration Resolution

 On-Chip Lookup Table Supports Multipoint

Calibration Temperature Correction

S Supports Both Current and Voltage-Bridge

Excitation

S Fast 85µs Step Response

S Sensor Fault Detection

The device is packaged in a 16-pin TSSOP and covers

the automotive AEC-Q100 Grade 1 temperature range of

-40NC to +125NC.

S Simple PCB Layout

S Single-Pin Digital Programming

S No External Trim Components Required
