Here is a link to a document for bq20z70 and bq20z90, it has a description of the production flow in section 22. /cfs-file/__key/communityserver-discussions-components-files/196/0714.1072.slua404_5B00_1_5D005F00_application-book-for-the-bq20z70-and-bq20z90…
James,
It takes a few minutes for the voltage measurements to update capacity. You also need to calibrate the pack. I attached the general applications book for gas gauges. You can reference Chapter 22 for a detailed production procedure. They calibrated…
1. Most of the orders do come from pack manufacturers, but there are plenty of end system manufacturers that use these devices as well.
2. Yes, you will need to get access to the cells to use the bq20z45 gauge. You may be able to divide down the full…
Yes, the PRO screen is where the commands can be written and read. Your next step after setting up data flash and calibration is to start the learning cycle process. To do that, you need to enable the Impedance Track algorithm. This turns on the FETs…
HI User,
Please find attached "The Instrumentation Amplifier Handbook", by Neil P. Albaugh from the Burr-Brown days a few years back. The handbook discusses several topics related to instrumentation amplifiers that are quite useful today.
On the section…
Hi A,
synchronous detection (alias phase sensitive detection or synchonous demodulation) can be performed this way:

to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
