Part Number: PGA103 Tool/software: We have actual problems with the PGA103, and the selection of gain 100. When selection the pins for gain 100, we have always gain 1. Several new chips does not work with the batch "79AP4". If i replace the chip with…
Part Number: PGA103 Other Parts Discussed in Thread: PGA113 Hi,
OFFSET in the data sheet is described as "RTI". I usually think of it as "Refered to input".
As the RTI value seems to have a large offset, is the OFFSET value already multiplied by GAIN…
Part Number: PGA103 Hi, support team
My customer has the questions as follow:
I am using PGA103U for one of my prototype develpment, but the application notes suggest +/-15V for offset trimming
Can I use +/- 3.3 V or +/-2.5V for offet trimming?…
Part Number: PGA103 Other Parts Discussed in Thread: PGA112 , PGA116 , PGA117 , PGA113 Hi,
I couldn't find a PGA with gain of 1, 2, 4, 10, 16, 32. Something similar to Microchip MCP6S21. Can you help to advise?
HI, dear:
The circuit of PGA103 is shown as fig.1. The source is input by pin 4, the output is pin 6.
Fig.1. the circuit of the PGA103
The source of the input signal has some dc offset, but they are small compared to the input signal. The input…
Part Number: PGA103 Other Parts Discussed in Thread: PGA204 Hi, dear:
I chose the PGA103 used in my design, and found the output of signal is cut off when the supply is ±5V. the output is limited between ±1.5V. You advised me to chose PGA204 because…
Other Parts Discussed in Thread: PGA103 Hi,
is it possible to get simulation model parameter for the programmable gain amplifier PGA103?
I would like to perform simulations in LTSpice to check, if this device might be suitable for my application.…
Other Parts Discussed in Thread: DAC11001A , PGA202 , PGA103 , PGA280 , PGA281 , OPA4182 , OPA4191 , OPA1604 I am looking for a PGA for the output from DAC11001A to be able to output up to +/-10V, but also take a 5V output down to 0.5V. Do you have any…
Hello Amy,
The PGA202 and PGA103 are the only programmable gain amplifiers that support the gains of 1, 10, 100 and the +/-10V power supplies.
The PGA103 offers single ended input with noise density of 11nV/sqrt(Hz) and low frequency noise 0.6uVp…
