Hello：
I am using LF353. When I ordered a new batch of LF353, the output deviation of out(7pin) was very large during the test.
Want to know, what reason is caused.
The verification method is as follows:
1.Cross validation： verification results, problems follow IC
2. The resistance and capacitance of LF353 differential output series were removed, but the problem remained unchanged.
3.Failure IC is tested under the same conditions as normal IC.
| IF353 | Differential input voltage(mV)(5pin& 6pin) | 7pin(mV) | 1pin(mV) |
|
Test normal IF353
|
100.1 | 93.1 | 93.3 |
| Test failure IF353 |
100.3 | 110.2 |
110.9 |
.
Best Regards
Leon
