ZSSC3026

Low Power, High Resolution 16-Bit

Sensor Signal Conditioner

Datasheet

Brief Description

Benefits

The ZSSC3026 is a sensor signal conditioner (SSC)

integrated circuit for high-accuracy amplification and

analog-to-digital conversion of a differential input

signal. Developed for correction of resistive bridge

sensors and optimized for high-resolution altimeter

module applications, the ZSSC3026 can perform

offset, span, and 1^stand 2^ndorder temperature com-

pensation of the measured signal. It can also provide

a corrected temperature output measured with an

internal sensor. The corrected measurement values

are provided at the digital output pins, which can be

configured as I²C™* (≤3.4MHz) or SPI (≤20MHz).

•

Excellent for low-voltage and low-power battery

applications

•

Integrated 18-bit calibration math DSP

Costs minimized via one-pass calibration

No external trimming components required

Highly integrated CMOS design

Physical Characteristics

•

Supply voltage range: 1.8 to 3.6V

Current consumption: 900µA (operating mode)

Sleep State current: 50nA (typical)

Digital compensation of the signal offset, sensitivity,

temperature, and non-linearity is accomplished via

an 18-bit internal digital signal processor (DSP) run-

ning a correction algorithm. Calibration coefficients

are stored on-chip in a highly reliable, non-volatile,

multiple-time programmable (MTP) memory. Prog-

ramming the ZSSC3026 is simple via the serial

interface. An internal charge pump provides the

programming voltage. The interface is used for the

PC-controlled calibration procedure, which programs

the calibration coefficients in memory. The digital

mating is fast and precise, eliminating the overhead

normally associated with trimming external com-

ponents and multi-pass calibration routines.

Temperature resolution: <0.003K/LSB

Operation temperatures depending on part

number: –40°C to +85°C

•

Small die size

Delivery options: die for wafer bonding, bumped

die for Flip Chip, PQFN24

Typical Applications

The ZSSC3026 is designed for operation in cali-

brated resistive (e.g., pressure) sensor modules:

•

Barometric altitude measurement for portable

navigation

•

Altitude measurement for emergency call

systems and car navigation

Features

•

Flexible, programmable analog front-end design;

up to 16-bit scalable, charge-balancing two-

segment analog-to-digital converter (ADC)

•

Inside hard disk pressure measurement

Weather forecast

Fan control

•

Fully programmable gain amplifier for optimizing

sensor signals: gain range 14 to 72 (linear)

ZSSC3026 Application Example

•

Internal auto-compensated temperature sensor

Digital compensation of individual sensor offset;

1^stand 2^ndorder compensation of sensor gain

•

Digital compensation of 1^stand 2^ndorder tem-

perature gain and offset drift

•

Intelligent power management unit

Layout customized for die-die bonding with

sensor for high-density chip-on-board assembly

•

Typical sensor elements can achieve accuracy of

better than ±0.10% FSO @ -40 to 85°C
