Product details
Overview
ZSSC3170FA2T from Integrated Device Technology (IDT) is an AEC-Q100-qualified automotive sensor signal conditioner IC designed to condition resistive bridge sensor outputs with digital LIN or PWM interface output. It delivers ±0.50% FSO accuracy over −40°C to +125°C, supports up to 430 Hz data conversion rate, and integrates 16-bit RISC microcontroller-based compensation for offset, sensitivity, temperature drift (up to 2nd order), and nonlinearity (up to 3rd order). It is used in automotive pressure, force, and level sensing systems requiring end-of-line calibration and robust EMC performance.
For engineers reviewing the ZSSC3170FA2T datasheet, ZSSC3170FA2T pinout, ZSSC3170FA2T application, or ZSSC3170FA2T equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade specifications, real-world application mappings, and two rigorously cross-checked alternative parts - all aligned to IDT's official ZSSC3170 revision F documentation.
Technical Context
The ZSSC3170FA2T implements a dual-stage analog front-end with programmable gain amplifier (PGA) offering 12 selectable gain settings (2× to 420×), enabling precise amplification of bridge signals from 1.8 mV/V to 267 mV/V. Its 14-bit ADC supports configurable resolution modes and integrates digital compensation using coefficients stored in automotive-certified EEPROM.
Digital output is delivered via either LIN 2.1-compliant transceiver (with load-dump protection up to ±40 V on LIN pin) or dual PWM outputs (HOUT/LOUT) supporting high-side or low-side switch configurations. Temperature measurement is supported via internal diode, external diode, or RTD inputs, with dedicated conditioning for both sensor correction and LIN-mode temperature reporting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar sensor signal conditioning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1452AUA+ | 16-bit sigma-delta ADC, analog-only compensation (no integrated MCU), requires external EEPROM and microcontroller for full correction | Lacks native LIN/PWM output; needs external transceiver or PWM generator; suited for custom analog signal chains | Choose when design already includes host MCU and requires maximum analog flexibility over integrated digital output |
| AD8555ARZ | Chopper-stabilized instrumentation amp + programmable gain + 16-bit ADC; no built-in LIN/PWM interface or EEPROM; operates up to +125°C only | Requires external LIN transceiver and firmware for compensation; limited to non-safety-critical cabin applications | Prefer for cost-sensitive cabin sensors where AEC-Q100 Grade 0 and end-of-line calibration are not required |
Compared with MAX1452AUA+ and AD8555ARZ, the ZSSC3170FA2T uniquely integrates LIN/PWM output, automotive EEPROM, and on-chip RISC-based compensation - reducing BOM count by ≥4 components and eliminating host MCU dependency for basic sensor reporting.

FAQ
What is the operating temperature range qualified for ZSSC3170FA2T?
ZSSC3170FA2T is AEC-Q100 qualified for −40°C to +125°C continuous operation, with extended capability up to +150°C for 1000 hours. This Grade 0 rating enables deployment in engine bay and transmission environments where ambient temperatures exceed standard industrial limits. The device maintains ±0.50% FSO accuracy across the full −40°C to +125°C range, verified per datasheet Table 1.3.8.4.
Does ZSSC3170FA2T support both high-side and low-side PWM switching?
Yes, ZSSC3170FA2T supports both configurations via dedicated HOUT (high-side switch) and LOUT (low-side switch) pins. In PWM mode, users select HSS or LSS operation through EEPROM configuration. Each output drives up to 15 mA with 0.5 V low-level and 4 V high-level voltage compliance, enabling direct interface with solenoids, LEDs, or external drivers without additional level-shifting circuitry.
How does ZSSC3170FA2T perform end-of-line calibration?
ZSSC3170FA2T enables single-pass end-of-line calibration using its I²C interface (SCL/SDA) to read raw ADC values while applying known stimuli. Calibration coefficients for offset, gain, temperature drift, and nonlinearity are computed externally and written to its automotive EEPROM. No external trimming components are required, and LIN or PWM output reflects fully compensated values immediately after programming - reducing final test time and fixture complexity.
Is ZSSC3170FA2T compatible with LIN 2.1 specification?
Yes, ZSSC3170FA2T complies with LIN specifications 1.3, 2.0, and 2.1 as stated in its official datasheet features list. Its LIN transceiver includes recessive/dominant level detection, slew rate control (0.5–3 V/µs), and ±40 V load-dump protection on the LIN pin. Frame content is configurable via EEPROM, allowing OEMs to define custom PID assignments and payload structures within LIN 2.1 publisher constraints.
What temperature sensing options does ZSSC3170FA2T support?
ZSSC3170FA2T supports three temperature sensing paths: internal diode (for die temperature), external diode (VTN1/VTN2), and external RTD/resistor (VTN1/VTN2). The selected sensor is used both for compensating bridge signal errors and - in LIN mode - for reporting media temperature. Gain and offset compensation for external sensors are programmable up to 2nd-order nonlinearity, ensuring accurate thermal correction across the full operating range.
