Ariel,
I have an EVM on order. I can test the settling of the PGA in the lab. Order placed 9/21/2023.
The point of removing R48 is to isolate the PGA output from the remainder of the circuit and to check if the settling is impacted by that circuit. You…
Hi Emanuel,
Emanuel Soares said: A: Plase consider also the correction for the R59 connection to the AVREF not to the PVC_REF:
Thanks for the clarification, with this node connected to 3.3V, the DC reference to the inverting terminal is larger than the…

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 stages…
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 Good day. We have some issues with programmable gain amplifier PGA113. The circuit block of this IC starts to generate noise as the PCB takes shock or vibration. Amplitude of noise depends on impact force and on some level have its…
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 two…
Part Number: PGA113 Hi All
Is there any Spice model for this part or at least the amplifier within? What I am interested in is its stability with various output capacitive loads.

Part Number: PGA113 Other Parts Discussed in Thread: OPA333 Hi,
below is the schematic and outpu waveform:
you can see that the postive amplitude of output is distortion.
CH1 input :11.2~12mV 160Hz ; CH0/VCAL float ; Gain of CH1=10
why the postive amilitude…
Part Number: PGA113 Hi Team,
My customer required a variable gain amplifier with anti- aliasing filter, in which they can set cutt-off Frequencies ( Fc1= 4.7KHz and Fc2= 10KHz). Please help with your suggestion and inputs.
Regards, Shinu Mathew.
