Product details
Overview
ZSSC3135BE1B from Integrated Device Technology (IDT) is a sensor signal conditioner IC designed specifically for piezoresistive bridge sensors in automotive and industrial systems. It integrates a 16-bit RISC microcontroller, programmable gain amplifier (PGA) with analog gain up to 105, 13/14-bit ADC, and on-chip EEPROM for one-pass calibration. The device delivers ratiometric analog voltage output (12.4-bit effective resolution) or ZACwire™ digital interface, supporting operation from −40°C to +150°C.
For engineers reviewing the ZSSC3135BE1B datasheet, ZSSC3135BE1B pinout, ZSSC3135BE1B application, or ZSSC3135BE1B equivalent, key selection criteria include its AEC-Q100 qualification, ±0.25% FSO accuracy over −25°C to +85°C, high-voltage protection up to 33 V, reverse polarity and short-circuit protection, and support for external temperature sensing via diode or thermistor.
Technical Context
The ZSSC3135BE1B implements a fully differential analog front-end with programmable gain amplifier (PGA), multiplexer, and full-differential switched-capacitor ADC. Its correction algorithm compensates offset, sensitivity, temperature drift, and non-linearity using coefficients stored in on-chip EEPROM.
It supports dual output modes: ratiometric analog voltage (5–95% VDDE, 12-bit DAC resolution) or ZACwire™ one-wire digital interface. Calibration is performed via I²C™ or ZACwire™ during end-of-line programming, with no external trimming components required.

FAQ
What is the maximum operating temperature supported by the ZSSC3135BE1B?
The ZSSC3135BE1B is rated for operation from −40°C to +150°C, verified per AEC-Q100 stress testing. This extended temperature range is enabled by its SSOP14 package and internal thermal protection circuitry, making it suitable for under-hood automotive and high-temperature industrial environments where standard commercial-grade ICs would fail.
Does the ZSSC3135BE1B require external calibration components?
No, the ZSSC3135BE1B does not require external calibration components. Its on-chip 16-bit RISC microcontroller executes sensor-specific correction algorithms using calibration coefficients stored in internal EEPROM. One-pass end-of-line calibration via I²C™ or ZACwire™ eliminates trim pots, external DACs, or lookup tables - reducing bill-of-materials and assembly steps.
Can the ZSSC3135BE1B interface with an external thermistor for temperature compensation?
Yes, the ZSSC3135BE1B supports external thermistor-based temperature sensing through its IRTEMP pin, which provides a programmable 6–20 µA bias current. The device measures thermistor voltage via the VTSER channel and applies temperature compensation using coefficients stored in EEPROM - confirmed in Section 1.3.3.5 and Figure 3.3 of the datasheet.
What output interface options does the ZSSC3135BE1B provide?
The ZSSC3135BE1B offers two configurable output interfaces: a ratiometric analog voltage output (AOUT pin, 5–95% VDDE, 12.4-bit effective resolution) and a digital ZACwire™ one-wire interface (OUT pin). Both are selectable via EEPROM configuration; I²C™ is used exclusively for setup and calibration, not for continuous output streaming.
How does the ZSSC3135BE1B handle sensor fault detection?
The ZSSC3135BE1B performs real-time sensor health monitoring including open-circuit detection (≥100 kΩ threshold) and short-circuit detection (≤50 Ω threshold) on bridge inputs. These diagnostics are executed automatically during each measurement cycle and reported via status bits accessible through I²C™ or ZACwire™ - enabling fail-safe behavior in safety-critical systems without external circuitry.
