Product details
Overview
ZSC31150GEG1-T from Integrated Device Technology (IDT) is an AEC-Q100-qualified automotive sensor signal conditioner IC designed for high-accuracy digital compensation of bridge sensor signals. It integrates a 16-bit RISC microcontroller, 12-bit DAC, 13–16-bit ADC, EEPROM, and dual digital interfaces (I²C and ZACwire™), delivering 0.25% FSO accuracy at −25°C to +85°C with analog voltage output or digital readout. It supports ratiometric bridge excitation in voltage or constant-current mode and operates across −40°C to +150°C.
For engineers reviewing the ZSC31150GEG1-T datasheet, ZSC31150GEG1-T pinout, ZSC31150GEG1-T application, or ZSC31150GEG1-T equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade performance specs, and real-world calibration and interface implementation details - all specific to the SSOP14 package with extended temperature range.
Technical Context
The ZSC31150GEG1-T implements a closed-loop digital correction architecture: differential bridge signals are amplified by a programmable gain amplifier (PGA), digitized by a 13–16-bit sigma-delta ADC, then corrected using sensor-specific coefficients stored in on-chip EEPROM. The integrated 16-bit RISC CMC executes a ROM-resident correction algorithm covering offset, sensitivity, temperature drift (via internal diode, external diode, thermistor, or bridge resistance), and non-linearity.
It supports two configurable output modes: ratiometric analog voltage (5–95% VDDE, 12.4-bit effective resolution) or digital output via I²C (400 kHz) or ZACwire™ one-wire interface. Calibration is performed end-of-line via either interface, enabling digital mating of sensor and IC without laser trimming or external components.
Key Specifications

Pinout & Package
Package: 14-pin SSOP (5.0 × 6.2 mm, 0.635 mm pitch), wettable flanks not applicable - standard gull-wing lead finish per ordering code ZSC31150GEG1-T.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDDA) | Analog Supply Input | 4.5–5.5 V analog rail; powers PGA, ADC, DAC, and internal bias circuits - must be decoupled with 100 nF capacitor |
| 2 (VSSA) | Analog Ground | Reference for all analog circuitry; separate from digital ground to minimize noise coupling into sensitive bridge inputs |
| 3 (SDA) | I²C Data Line | Open-drain bidirectional interface; requires external pull-up (typically 2.2–10 kΩ) to VDDA for communication and calibration |
| 4 (SCL) | I²C Clock Line | Input-only clock for I²C master; supports up to 400 kHz; synchronizes EEPROM programming and register reads |
| 5 (n.c.) | No Connect | Internally unused; must be left floating or tied to VSSA - no routing or soldering required |
| 6 (VDD) | Digital Supply Input | Same 4.5–5.5 V as VDDA; powers digital block (CMC, EEPROM, I²C/ZACwire logic); may share supply with VDDA if well-decoupled |
| 7 (VDDE) | Output Supply Reference | Provides reference for ratiometric AOUT; connects directly to load-side supply - enables true ratiometricity independent of VDDA stability |
| 8 (IRTEMP) | Temperature Sensor Bias | Current source output (6–20 µA) for external diode or thermistor; enables precise temperature compensation without external bias circuitry |
| 9 (VBR_T) | Bridge Top Input | Differential positive input for bridge sensor; accepts common-mode voltages from 0.29×VDDA to 0.65×VDDA depending on PGA gain setting |
| 10 (VBP) | Bridge Positive Excitation | Voltage or current excitation output for top of bridge; configurable for ratiometric or constant-current drive per sensor requirements |
| 11 (VBR_B) | Bridge Bottom Input | Differential negative input for bridge sensor; matched to VBR_T for optimal CMRR and offset rejection |
| 12 (VBN) | Bridge Negative Excitation | Return path for bridge excitation; completes current loop in constant-current mode or serves as reference in voltage mode |
| 13 (AOUT) | Analog Output | Ratiometric voltage output (5–95% VDDE); drives ≥2 kΩ loads with 2.5 mA sink/source capability and <10 mVpp noise |
| 14 (VSSE) | Output Ground | Return path for AOUT and VDDE; isolated from VSSA to maintain ratiometric integrity and avoid ground loop errors |

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 DAC, 16-bit ADC, but no integrated microcontroller; requires external EEPROM and host processor for compensation math | Lacks on-chip correction algorithm and digital mating capability; calibration requires external PC software and host MCU coordination | Choose when legacy analog signal chain redesign is constrained and host MCU resources are available for real-time compensation |

FAQ
What is the operating temperature range certified for ZSC31150GEG1-T?
The ZSC31150GEG1-T is specified for −40°C to +150°C ambient operation and is AEC-Q100 Grade 0 qualified. This extended range is validated for use in under-hood and transmission-mounted applications where thermal stress exceeds standard commercial or industrial limits. The device maintains 0.5% FSO accuracy across −40°C to +125°C and 1.0% FSO up to +150°C.
Does ZSC31150GEG1-T support both voltage and current excitation for bridge sensors?
Yes, ZSC31150GEG1-T supports configurable bridge excitation: VBP and VBN pins can be set for ratiometric voltage drive or constant-current mode. In current mode, it delivers up to 2 mA with programmable compliance, accommodating bridge resistances from 10 kΩ down to 2 kΩ - eliminating external current sources or voltage dividers in the ZSC31150GEG1-T signal chain.
How is calibration performed for ZSC31150GEG1-T, and what interfaces are supported?
Calibration for ZSC31150GEG1-T is performed end-of-line using either the I²C interface (400 kHz) or ZACwire™ one-wire interface. Both allow PC-controlled programming of sensor-specific coefficients into on-chip EEPROM. No external trimming components or laser systems are needed - the ZSC31150GEG1-T digitally mates with its paired sensor during final test, ensuring repeatability and reducing calibration floor space.
What protection features does ZSC31150GEG1-T include for automotive environments?
ZSC31150GEG1-T includes ±33 V absolute maximum rating on VDDE and AOUT pins, reverse polarity protection on supply inputs, short-circuit protection on AOUT, and built-in sensor open/short detection (100 kΩ open threshold, 50 Ω short threshold). These features meet ISO 7637-2 load dump and reverse battery requirements and reduce need for external TVS or protection ICs in the ZSC31150GEG1-T design.
Can ZSC31150GEG1-T output both analog and digital signals simultaneously?
No - ZSC31150GEG1-T supports output multiplexing: either ratiometric analog voltage on AOUT, or digital data via I²C or ZACwire™. The output mode is configured during EEPROM programming and remains fixed until reprogrammed. However, digital interfaces remain active for configuration and diagnostics even when analog output is selected - enabling live calibration updates without interrupting analog signal delivery.
