NXP Semiconductors BRKTSTBCDP5004

Overview

BRKTSTBCDP5004 from Freescale Semiconductor is a differential pressure sensor IC with 0–3.92 kPa full-scale range, ratiometric analog output (VOUT), on-chip temperature compensation, and ±2.5% accuracy over 10 °C to 60 °C with autozero - designed for microcontroller-based liquid level and respiratory equipment sensing.

For engineers reviewing the BRKTSTBCDP5004 datasheet, BRKTSTBCDP5004 pinout, BRKTSTBCDP5004 application, or BRKTSTBCDP5004 equivalent, this page delivers verified mechanical interface data, calibrated output behavior, supply voltage dependency, zero-pressure offset tolerance, and media compatibility guidance for dry-air systems.

Technical Context

The BRKTSTBCDP5004 integrates a monolithic silicon piezoresistive sensing element with thin-film metallization and bipolar signal conditioning circuitry. Its transfer function is VOUT = VS × [(0.2 × P) + 0.2], where VS = 4.75–5.25 VDC and P is differential pressure in kPa.

On-chip temperature compensation corrects span and offset drift across 10 °C to 60 °C using integrated calibration circuitry. The device operates ratiometrically, meaning output scale and offset track supply voltage variations, simplifying A/D interfacing in embedded systems.

Key Specifications

Pinout & Package

BRKTSTBCDP5004 uses a small-outline through-hole package (case 98ASB17757C), thermoplastic PPS housing with stainless steel cap, and 8-pin dual-in-line configuration. Pins 1, 5–8 are internal DNC terminals; only pins 2 (VS), 3 (GND), and 4 (VOUT) are externally connected.

FAQ

What is the exact pressure range and output behavior of the BRKTSTBCDP5004?

The BRKTSTBCDP5004 has a differential pressure range of 0–3.92 kPa (0–400 mm H₂O). Its output voltage follows VOUT = VS × [(0.2 × P) + 0.2], yielding 0.75–1.25 V at zero pressure and 3.0–3.92 V at full scale when VS = 5.0 VDC. This ratiometric relationship holds across the specified supply range of 4.75–5.25 VDC, making BRKTSTBCDP5004 ideal for direct MCU A/D interfacing without external references.

Does the BRKTSTBCDP5004 require external temperature compensation or calibration?

No - the BRKTSTBCDP5004 integrates on-chip temperature compensation circuitry that corrects both span and offset drift across +10 °C to +60 °C. Factory calibration and autozero programming eliminate the need for external thermistors, lookup tables, or software compensation algorithms. However, BRKTSTBCDP5004 accuracy specifications assume use within its compensated temperature band; operation outside +10 °C to +60 °C may degrade performance beyond ±2.5% VFSS.

Can the BRKTSTBCDP5004 be used with media other than dry air?

The BRKTSTBCDP5004 is qualified and reliability-tested exclusively for dry air. Using other media - including humid air, water vapor, oils, or cleaning agents - may cause long-term drift, gel degradation, or diaphragm corrosion. Freescale explicitly states that adverse effects on performance and reliability are possible. If non-dry-air operation is required, consult NXP's factory for media-specific validation data before selecting BRKTSTBCDP5004.

What are the critical PCB layout considerations for the BRKTSTBCDP5004?

For BRKTSTBCDP5004, maintain separate analog and digital ground planes joined at a single point near the GND pin (Pin 3); route VS and VOUT traces away from noisy digital lines; place 1.0 μF and 0.01 μF decoupling capacitors close to Pin 2 (VS); and avoid solder mask bridging on the 8-pin DIP footprint. The recommended minimum pad dimensions follow case 98ASB17757C mechanical drawings - incorrect sizing causes poor solder wetting or tombstoning during wave soldering.

How does autozero affect the accuracy specification of the BRKTSTBCDP5004?

Autozero improves BRKTSTBCDP5004 accuracy from ±6.25% VFSS (without autozero) to ±2.5% VFSS over 100–400 mm H₂O, provided the zero-pressure reading is captured and subtracted during normal operation. This assumes ≤±5 °C temperature change between autozero and measurement. Mechanical stress or mounting position shifts can impact zero-point stability, so BRKTSTBCDP5004 autozero should be performed in final mechanical configuration - not on test fixtures.
