PGA202: Need suggestion

David Chance

Part Number: PGA202
Other Parts Discussed in Thread: PGA204,

We have been using TI's PGA204 (soic) in our design for many years, but recently, we can't find it anywhere now, so we are looking for a simple replacement without changing the firmware.

We can find PGA204 (DIP), but we can't fit it in our PCB due to its size (16 pin)

So I am looking at the PGA202. which barely fits in our PCB (14-pin), and it has the same gains, and I can drive both with 12V....

Other than a poorer front-end end from 202, where can i find the line-by-line comparison between the two?

ps, if anyone knows where to order PGA204 (SOIC), i will greatly appreciate the help!

Hi David,

We do have a parametric search tool where you can see all of the PGAs in our portfolio. https://www.ti.com/amplifier-circuit/pga-vga/products.html#sort=-1;asc&

Selecting two or more devices and then "compare" will show a line by line comparison between devices.https://www.ti.com/compare-products/?id=1913&type=GPT&partList=PGA202,PGA204&columnList=3229,480,512,358max,358min,2954,2955,261011,1811,511,554max,89,22typ,1192,1130,-4

This has useful information about max gain, power supply, package size, pin count, channel count, operating range, etc.

This tool was designed mostly for op amps and data converters so as you can see it is not particularly optimized to produce a detailed PGA comparison table, although it is a good place to start. The best method is to simply compare the datasheet specification tables.
