Frequently Asked Questions
What is the PGA309AIPWT and what does it do?
The PGA309AIPWT is a programmable gain amplifier (PGA) from Texas Instruments designed for sensor signal conditioning. It provides programmable gain from 4V/V to 128V/V in 7 discrete steps, with an integrated 8-bit DAC for offset and span calibration of bridge sensors such as strain gauges and pressure transducers.
What supply voltage does the PGA309AIPWT require?
The PGA309AIPWT operates from a single supply voltage of 2.7V to 5.5V, making it compatible with both 3.3V and 5V systems. This wide supply range is well-suited for battery-powered and industrial applications.
What package and pin count does the PGA309AIPWT come in?
The PGA309AIPWT comes in a 16-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm pitch, suitable for compact PCB designs. The PW suffix in the part number denotes this TSSOP package.
What are common alternatives to the PGA309AIPWT?
Common alternatives include the INA333 (Texas Instruments, low-power instrumentation amplifier), AD8221 (Analog Devices, precision instrumentation amp), and PGA308AIPWT (TI predecessor with similar bridge sensor conditioning capability). Selection depends on required gain range, supply voltage, and calibration needs.
Is the PGA309AIPWT RoHS compliant and what is its operating temperature?
Yes, the PGA309AIPWT is RoHS compliant and lead-free. It is rated for industrial operating temperatures from -40°C to +85°C, making it suitable for factory automation, medical equipment, and outdoor industrial sensors.
