NXP Semiconductors MPX2300DT1

Overview

MPX2300DT1 from Freescale Semiconductor is a differential pressure sensor with 0–40 kPa (0–300 mmHg) range, ratiometric output, and on-chip thin-film temperature compensation-designed specifically for invasive medical applications including blood pressure monitoring and pressure catheters. It features polysulfone housing (ISO 10993 compliant), silicone dielectric gel isolation, and a Chip Pak package with exposed die on front side.

For engineers reviewing the MPX2300DT1 datasheet, MPX2300DT1 pinout, MPX2300DT1 application, or MPX2300DT1 equivalent, key selection considerations include its biocompatible materials, defibrillation-rated electrical isolation, narrow operating temperature range (+15°C to +40°C), and requirement for external front-side protection in end-user housing.

Technical Context

The MPX2300DT1 integrates a silicon piezoresistive sensing element with on-die thin-film temperature compensation circuitry, delivering ratiometric output referenced to supply voltage (VS = 6 V ±0.2 V). Its differential architecture measures pressure across two ports applied to the backside of the chip pak, while the front side exposes die and wire bonds requiring customer-provided mechanical and fluidic protection.

Electrical performance is defined at 6 VDC excitation and 25°C, with full-scale span of 3.006 mV typical, linearity + hysteresis ≤ ±1.5% VFSS, and zero offset bounded by ±0.75 mV. Temperature coefficients are tightly controlled: ±0.1%/°C for sensitivity and full-scale span, and ±9.0 μV/°C for offset.

Key Specifications

Pinout & Package

MPX2300DT1 uses the Chip Pak package (Case 98ASB13355C), a miniature surface-mount module with dimensions 6.10–6.60 mm × 8.89–9.40 mm × 3.56–3.81 mm (L×W×H), featuring an exposed silicon die on the front side and pressure interface on the backside.

FAQ

What is the pressure port configuration of the MPX2300DT1?

The MPX2300DT1 is a differential pressure sensor with two isolated pressure ports located on the backside of the Chip Pak package. Pressure is applied to the rear surface of the device; the front side contains the exposed silicon die and wire bonds, which must be protected by the customer's housing. This configuration enables precise differential measurement in medical fluidic circuits without internal reference cavities.

Does the MPX2300DT1 require external temperature compensation?

No, the MPX2300DT1 includes on-chip thin-film temperature compensation calibrated over +15°C to +40°C. Its sensitivity and full-scale span exhibit only ±0.1%/°C variation, and offset drift is limited to ±9.0 μV/°C - eliminating the need for external thermistors or digital correction algorithms in most clinical applications where the device operates within its specified temperature range.

Can the MPX2300DT1 be sterilized using ethylene oxide?

Yes, the MPX2300DT1 is designed for ethylene oxide (EtO) sterilization. Its rigid housing is molded from medical-grade polysulfone (ISO 10993-5/10/11 compliant), and the silicone dielectric gel meets USP Class V biological testing requirements - both validated for compatibility with standard EtO sterilization cycles used in disposable medical device manufacturing.

What is the maximum allowable supply voltage for the MPX2300DT1?

The MPX2300DT1 is rated for a supply voltage of 6.0 VDC ±0.2 V. While the absolute maximum rating allows up to 10 VDC, operation above 6.2 V may induce self-heating errors that degrade accuracy. Freescale explicitly recommends regulated 6 V excitation to maintain specified linearity, offset, and temperature coefficient performance.

Is front-side protection required for the MPX2300DT1 in end-use applications?

Yes, the MPX2300DT1 datasheet explicitly states that the die and wire bonds are exposed on the front side of the Chip Pak package and must be protected by the customer's housing. This protection is essential to prevent mechanical damage, fluid ingress, and electrical shorting - especially in saline-rich environments like blood pressure monitoring or infusion systems.
