PRODUCTION DATA.
The PGA302 device must be paired with an external sensor, and can be used in a variety of applications depending on the chosen sensor. When choosing a sensor, the most important consideration is to ensure that the voltages applied to the analog input pins on the PGA302 stay within the recommended operating range of 0.2 V minimum and 4.2 V maximum. A programmable gain stage allows a wide selection of sensors to be used while still maximizing the input range of the 16-Bit ADC. The PGA302’s internally regulated bridge voltage supply and independent current source for temperature sensors eliminates the need for externally excited sensors. The interface options include I2C and OWI.
