Product details
Overview
ZSC31015EAG1-T from Integrated Device Technology (IDT) is a programmable analog-output sensor signal conditioner for piezoresistive bridge sensors, featuring 14-bit ADC resolution, 12-bit ratiometric analog voltage output, and integrated ZACwire™ one-wire digital interface. It delivers ±0.1% FSO accuracy from –25°C to +85°C, supports rail-to-rail output with 1ms typical response time, and enables PC-based calibration without external trimming components - used in industrial pressure transducers and automotive sensor modules.
For engineers reviewing the ZSC31015EAG1-T datasheet, ZSC31015EAG1-T pinout, ZSC31015EAG1-T application, or ZSC31015EAG1-T equivalent, key selection considerations include its diagnostic capability (bridge short detection, EEPROM signature, power loss detection), dual temperature compensation (internal PTAT or external diode), and support for supply voltages from 2.7 V to 5.5 V (or up to 30 V with external JFET).
Technical Context
The ZSC31015EAG1-T integrates a chopper-stabilized differential preamplifier with four selectable analog gains (6/24/48/96), a 14-bit charge-balanced ADC, digital correction engine for offset/sensitivity/temperature drift/nonlinearity, and a 12-bit DAC with programmable clipping. Its digital core includes on-chip EEPROM for storing calibration coefficients and device ID, accessed via ZACwire™ serial interface.
Signal flow begins at the bridge inputs (VBP/VBN), proceeds through gain-adjusted amplification and digitization, applies real-time polynomial correction using stored coefficients, then outputs either as analog voltage (SIG™ pin) or 16-bit digital packet. Diagnostics operate concurrently - including bridge connection checks, short detection, and power-loss monitoring - all configurable via EEPROM bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | 14-bit - provides ≥16,384 discrete steps for high-precision bridge measurement before digital correction. |
| Analog Output Resolution | 12-bit ratiometric - delivers 4,096 output levels referenced to VDD, supporting 0.025% FSO linearity error. |
| Accuracy (Digital Mode) | ±0.1% FSO @ –25°C to +85°C - guaranteed system-level accuracy for calibrated bridge-sensor pairs without external compensation. |
| Response Time | 1 ms (typical) - enables real-time closed-loop control in fast-acting pressure or force sensing systems. |
| Supply Voltage Range | 2.7 V to 5.5 V - operates directly from standard microcontroller rails; extended to 30 V with external JFET regulator. |
| Operating Temperature | –50°C to +150°C - qualified for under-hood automotive and industrial harsh-environment applications. |
| Interface | ZACwire™ one-wire serial - enables single-pin PC-based calibration and coefficient programming without dedicated UART or SPI hardware. |

| VBP | Bridge positive input | Differential input for bridge's high-side output; accepts common-mode voltage from 1 V to (VDD – 1.3 V). |
| ExtTemp | External temperature sensor input | Accepts 150–800 mV diode voltage for enhanced thermal compensation beyond internal PTAT reference. |
| VBN | Bridge negative input | Differential input for bridge's low-side output; matched to VBP for common-mode rejection. |
| VSS | Ground reference | Analog ground return; required for power-loss detection diagnostic when pull-down load resistor is used. |
| SIG™ | Configurable output | Programmable as rail-to-rail ratiometric analog voltage (12-bit) or ZACwire™ digital serial output. |
| VDD | Supply input | 2.7–5.5 V main supply; powers analog/digital blocks and internal regulator; decoupling capacitor required (100–470 nF). |
| Vgate | JFET gate control | Drives external BSS169 JFET for overvoltage protection when VSUPPLY exceeds 5.5 V (e.g., 12 V/24 V automotive). |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar sensor signal conditioning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1452ACM+T | 16-bit DAC, 20-bit ADC, SPI interface only - no native one-wire; requires external EEPROM for calibration storage. | Lacks integrated diagnostics (no bridge short detection or EEPROM signature); higher component count for full functionality. | Preferred when SPI infrastructure exists and higher-resolution DAC is required; not drop-in due to interface and diagnostic gap. |
| PGA309AIPWPR | Analog-only signal chain (no ADC/DAC); relies on external MCU for digital correction and EEPROM storage. | No built-in digital compensation engine or ZACwire™ interface - calibration must be implemented externally. | Selected for cost-sensitive designs where MCU handles correction math and diagnostics; requires additional firmware development. |
Compared with ZSC31015EAG1-T, MAX1452ACM+T offers higher DAC resolution but lacks self-contained diagnostics and one-wire simplicity, while PGA309AIPWPR shifts computational burden to the host MCU and increases system-level validation effort.

FAQ
What is the primary function of the ZSC31015EAG1-T in a sensor system?
The ZSC31015EAG1-T serves as a fully integrated signal conditioner for piezoresistive bridge sensors, performing analog amplification, 14-bit digitization, digital correction of offset/sensitivity/temperature drift/nonlinearity, and configurable analog or one-wire digital output. It replaces external trimming components and enables factory calibration via ZACwire™, making it central to high-accuracy, low-BOM sensor modules.
Does the ZSC31015EAG1-T support both ratiometric and absolute analog voltage outputs?
Yes, the ZSC31015EAG1-T supports rail-to-rail ratiometric analog voltage output (referenced to VDD) and absolute analog voltage output modes. Ratiometric mode ensures output scaling matches supply variations - ideal for systems sharing VDD with the ADC - while absolute mode provides fixed-voltage referencing independent of supply fluctuations, enabled via internal voltage reference configuration.
How does the ZSC31015EAG1-T handle temperature compensation?
The ZSC31015EAG1-T provides dual temperature compensation: an internal PTAT reference for basic compensation, and optional external diode-based compensation via the ExtTemp pin. When an external diode is used, the IC measures its forward voltage (150–800 mV) to achieve tighter thermal correction across –50°C to +150°C, improving overall accuracy beyond what internal compensation alone delivers.
Can the ZSC31015EAG1-T operate from a 12 V or 24 V supply?
Yes, the ZSC31015EAG1-T can operate from 5.5 V to 30 V supplies when paired with an external JFET (e.g., BSS169) controlled by the Vgate pin. In this configuration, the JFET regulates the internal VDD rail to 2.7–5.5 V, enabling direct use in automotive 12 V/24 V environments while maintaining full functionality and diagnostic coverage.
What diagnostics are implemented inside the ZSC31015EAG1-T?
The ZSC31015EAG1-T implements on-chip diagnostics including EEPROM signature verification, bridge open-circuit detection, bridge short-circuit detection, power-loss flagging, and external temperature sensor connection checks. These functions are configurable via EEPROM bits and report status through dedicated diagnostic output levels (VDIA,H/VDIA,L) or embedded flags in digital output packets.
