Other Parts Discussed in Thread: PGA112 Hi Ti,
Im JD from Taiwan.
I had two question about PGA112.
<1> Document issue
PGA112 datasheet ,page 36 table 9
I calculate the Maximum Signal by Page 33 Vout = G x Vin - AVdd /2 x(G -1).
I calculate the Max…
Hi Bob,
I appreciate that you pass the idea to the definition team. I would be happy if they could see the need too.
Yes you can combine ADS1119 with PGA112 but this solution is more expansive, you need more space, increase compexity and risk in terms of…
Other Parts Discussed in Thread: PGA112 Hi Team,
We are about to start software development with the PGA112, but I wanted to check here first to see if there were any C code example drivers for interfacing with the half duplex SPI as I have never worked…
Other Parts Discussed in Thread: PGA112 Hello,
I am using a PGA112 with the following configuration:
VCCA = 3.0V
VCCD = 2.5V
VREF = 1.024V
AIN0 = 0-2V (100K impedance)
AIN1 = 0-2.5V (20K impedance)
With the gain set to 1:1, both channels seem to work fine…
Other Parts Discussed in Thread: PGA112 Hi,
I'm using a PGA112 stand-alone mode. I have some questions:
When setting up for SPI into the PGA112, is the data width (packet size) 8bits, or 16bits? It appears by the data sheet it is 16 bits...but want…
Other Parts Discussed in Thread: PGA113 Hi there,
http://www.ti.com/lit/ds/symlink/pga113.pdf On page 3, it says, the input offset voltage can be +/-100uV maximum I am not sure how to interpret this info. If we have AVdd=DVdd=3.3V, Vref=Vin=0.9V, what will…
Other Parts Discussed in Thread: PGA112 Hi,
I use programmable gain amplifier PGA112. The calibration function does not work. All 4 CAL functions measure "0" at the PGA out. Please, help me to calibrate the system.

Other Parts Discussed in Thread: PGA116 , PGA117 , PGA112 , PGA113 Hello alltogether,
I don't understand what the daisy-chain commands of PGA112, PGA113, PGA116, and PGA117 are for.
What happens if I use them on a single device?
What happens if I use…
Other Parts Discussed in Thread: PGA112 Hi,
I tested an Gain-programmable circuit which uses IC - PGA112. The circuit is shown as below:
The input signal is connected to C174 then into CH1. The amplified output can be measured at Min2 or RLine1. Its…
Dear John,
Schematic
A3: PGA112 and Upper side
Lower side:
J8,J9 is connector to 28027.
A2:
Confrim:
About your clarify: You are right, PGA112 in A3 board could be demaged.
Working Frenquency:
My signal is 40KHz, so C13…
