What are the key features of PGA117AIPWG4?
- Programmable gain from 1 V/V to 200 V/V selectable via SPI interface, enabling flexible signal conditioning without external resistor networks
- Rail-to-rail input and output swing on a 20-pin TSSOP package provides maximum dynamic range in 5 V single-supply data acquisition systems
- Integrated 10-channel analog multiplexer allows direct multi-sensor input selection, reducing external MUX ICs and simplifying PCB layout
What is PGA117AIPWG4 used for?
The PGA117AIPWG4 is ideal for precision data acquisition front-ends in industrial and medical instrumentation where multiple sensor signals at different amplitude levels must be amplified and digitized by a single ADC. Its SPI-programmable gain of 1 V/V to 200 V/V and integrated 10-input MUX allow a microcontroller to dynamically configure channel and gain, reducing component count. It also suits bridge sensor amplification and strain gauge signal conditioning in weigh-scale and pressure measurement systems.

Frequently Asked Questions
What gain range does the PGA117AIPWG4 support, and how is the gain selected?
The PGA117AIPWG4 supports programmable gain values of 1, 2, 5, 10, 20, 50, 100, and 200 V/V, selected digitally via a 3-wire SPI-compatible interface. This eliminates external gain-setting resistors and allows a microcontroller to reconfigure the amplifier gain in real time, making it well suited for multi-range sensor signal conditioning applications.
How many analog input channels does PGA117AIPWG4 integrate, and what does this mean for a multi-sensor design?
The PGA117AIPWG4 integrates a 10-channel analog multiplexer, allowing up to 10 independent sensor inputs to share a single programmable gain amplifier and ADC signal chain. This reduces external component count significantly compared to discrete MUX plus PGA topologies, and each channel can use a different gain setting selected via SPI before each conversion cycle.
What is the supply voltage range of PGA117AIPWG4, and is it compatible with 3.3 V microcontroller systems?
The PGA117AIPWG4 operates from a single supply voltage, and its rail-to-rail input and output allow it to handle signals from 0 V to the supply rail. While designed for 5 V single-supply operation, the SPI interface is compatible with 3.3 V logic levels when appropriate level-shifting is applied, enabling integration with modern low-voltage microcontrollers in industrial sensor platforms.
When would PGA117AIPWG4 be preferred over a discrete op-amp plus analog MUX combination?
PGA117AIPWG4 integrates a 10-input MUX, 8-gain-step programmable amplifier, and SPI control in a single 20-pin TSSOP package, replacing at least 2 discrete ICs and multiple gain-setting resistors. This integration reduces PCB area by roughly 40%, lowers BOM cost, and eliminates gain error introduced by resistor tolerances, making it the preferred choice for cost-sensitive multi-channel data acquisition designs with dynamic range requirements up to 200 V/V.
