Part Number: PGA113 Tool/software: Hi,
In the documentation it is not clear that Vref pin can be connected to GND via a suitable size capacitor to achieve AC signal programmable gain only while keeping a unity DC gain. Assuming that CH1 is used as the…
Part Number: PGA113 Other Parts Discussed in Thread: OPA392 We are measuring faint photodiode output with a transimpedance amplifier (uses AD8605) AC coupled into a PGA (uses PGA113) followed by a low-pass filter (uses LTC1563-2).
We modified a working…

Hi all.
I would like to use the PGA113 to set the first stage gain to the analog circuit on my sensor test board.
As you can see in the picture attached below, there are three different…

Hello to whom this may concern, This is the description of the situation: 1. Input ignal: The system need to be able to capture two types of signal (from a BLDC…
Part Number: PGA113 The timing diagrams of CLK, CS, and DIO of PGA113 are correct, and the related pin connections are okay, but pga113 cannot be amplified. The default magnification of input 0x2a50 is 1. I don’t know the reason?

Part Number: PGA113 Other Parts Discussed in Thread: OPA325 Hi All
I am using PGA113 in unity gain configuration to drive a C8051F507 uC A/D input with a sampling capacitance of 32pF and input multiplexer resistance of 3K. Do I need to isolate the…
Hi IK,
Unfortunately, the PGA11x family of devices was developed ~11 years ago and we currently don't have a SPICE model for this family of devices.
I have answered your other query regarding the PGA113 driving the 3kOhm mux series resistance and…

I try to test Gain control by using PGA113 but it not working on channel CH1 when i try to use CH0, CH0 replicate pre amplifire output as it is there is no any variation…
