The part number MPXV5010DP corresponds to a sensor from NXP Semiconductors (formerly Freescale), specifically a pressure sensor designed to measure differential pressure. Let’s break down the request into specific parts, as you asked for a detailed explanation:
1. Brand and Model:
Brand: NXP Semiconductors Model: MPXV5010DP2. Package Type:
The MPXV5010DP is typically available in a 6-pin package, specifically a DIP-6 (Dual In-line Package) configuration.
3. Pin Function Specifications and Circuit Principle:
Here’s a detailed breakdown of the 6 pins of the MPXV5010DP pressure sensor:
Pin Number Pin Name Pin Function Pin 1 Vout (Output) Analog output signal corresponding to the measured pressure. The voltage varies in proportion to the applied pressure. Pin 2 GND (Ground) Ground reference for the sensor circuit. It is connected to the common ground of the system. Pin 3 Vdd (Supply Voltage) Positive supply voltage input, typically 3.3V or 5V depending on the application. Pin 4 NC (No Connection) This pin has no connection and should be left floating or disconnected. Pin 5 NC (No Connection) Another non-connected pin for mechanical reasons. Pin 6 Vout (Output) Similar to Pin 1, it is an additional output pin that carries the analog output signal. It is internally tied to the same output as Pin 1.4. Detailed Pin Function Description:
Pin 1 (Vout/Output): This is the output pin of the sensor, which provides an analog voltage that varies with the differential pressure applied to the sensor. The sensor converts the measured pressure into an analog signal that can be read by an analog-to-digital converter (ADC). Pin 2 (GND/Ground): This pin serves as the ground reference for the sensor. It should be connected to the ground of your circuit to provide a common reference voltage for the sensor to function correctly. Pin 3 (Vdd/Supply Voltage): The Vdd pin is where the sensor gets its supply voltage. This pin can usually accept 3.3V to 5V depending on the operating conditions of the sensor and the desired pressure range. Pin 4 (NC/No Connection): This is a mechanically and electrically non-connected pin, which you do not need to connect to anything in your circuit. Pin 5 (NC/No Connection): Another pin with no electrical function. It is only part of the mechanical layout of the sensor and does not require any wiring. Pin 6 (Vout/Output): This pin also outputs the pressure-related voltage, similar to Pin 1. It’s an additional output pin that might be used in certain configurations.5.
