Part Number: PGA112
Hi TI team~
As far as I know, the PGA112 device doesn't offer a SPI interface with daisy-chain.
But I would like to use SPI communications to work with several PGA112 devices together.
These can be used common SPI interface…

via the SPI interface and the DIO pin it is possible ot read form the PGA112 device. What data can you actually read from it? I did not find this in the documentation.
Part Number: PGA112 Hello:
Really hoping I can get some help on this issue. Using a PGA112, connected as shown in the attached image, "PGA112_Connect.jpg"
Vdd is at 3.3V, Vref is at midpoint of 1.65, and connected to PGA112's vref input. If I am using…
Hi Thakur,
Programmable Gain instrumentation amplifiers (PGAs) are used in a large diversity of applications including data acquisition systems, high precision signal instrumentation and universal input industrial analog inputs.
PGA's are very often…
Part Number: PGA112 Hi,
One of my customers is using PGA112 and noticed the following:
Both the Analog and Digital part of the PGA112 are being supplied with 5V. As soon as the output goes into saturation [Vin x Gain >= 5V] CH1 stops being high…
Part Number: PGA112 Hi,
I have a question regarding -> Datasheet 9.1.1 OPAMP: Input Stage, transition between the NMOS and PMOS transistor.
Typically the offset voltage starts to show big deviations around VCC-1.5V (Fig. 66 and 67). This is different…
Hello Luke,
Please understand that most of our engineers are out for the holidays. It is most likely that we won't address your question until early January 2017.
Part Number: PGA112 Other Parts Discussed in Thread: REF3230 , OPA2364 , TINA-TI , OPA364 , OPA363 I am intending to use the PGA112 amplifier to measure voltages with a wide dynamic range. Peak voltage to be measured is 60 V, scaled to < 3V with a 100k…
