* Initial date of model creation:
|
|
|
53 |
* Feb.21/2017
|
|
|
54 |
*
|
|
|
55 |
* Revision History:
|
|
|
56 |
* Version 1: Initial，2017
|
|
|
57 |
* Version 2: Update OFFSET bias voltage,2022
|
|
|
58 |
*
|
|
|
59 |
* Recommendations:
|
|
|
60 |
* Use SIMETRIX (or SPICE 2G6; other simulators may require translation)
|
|
|
61 |
* For a quick, effective design, use a combination of: data sheet
|
|
|
62 |
* specs, bench testing, and simulations with this macromodel
|
|
|
63 |
* For PSpice .options ITL4=20 can be used for convergence
|
|
|
64 |
*
|
|
|
65 |
* Supported:
|
|
|
66 |
* Small Signal Transimpedance, Output Differential Voltage Vs Input DC Current for IOffset Variation, Output Differential Voltage Vs Offset Adjustment Current Input
|
|
|
67 |
* Supply Current Vs Input DC Current, Supply Current Vs Supply Voltage, Input Bias Voltage
|
|
|
68 |
* Model works only at temperature 27 degree celsius
|
|
|
69 |
*
|
|
|
70 |
* Not Supported:
|
|
|
71 |
* This model does not operate other than 27 degree celsius
|
|
|
72 |
*
|
|
|
73 |
* Known Discrepancies in Model vs. Datasheet:
|
|
|
74 |
* Bandwidth and Pulse Response mismatches from Datasheet.
