Some notes on Op-Amps
Accidentally re-read some datasheets today and found out that the MCP662 we quite happily used all over the cv-sections of the synkie does in fact not fit our symmetrical power supply of +-5V. Its max ratings is 6.5V – oops ! We’ll have to replace the all or the will fail some day…
so here some notes on the Op-Amps we are currently using:
LM833
- supports high supply voltage of +-18V
- not rail to rail
- only 10MHz gain-bandwidth-product
- 100dB open loop gain
- can offset color phase
- input-bias current of 1µA
MCP662
DON’T USE: Max 6.5V supply voltage
MAX4392
- nice bandwidth (70MHz), no phase problems
- ATTENTION very high input bias current: typ 5 max 15µA !
- Low open loop gain of 60dB
- Rail-to-rail
- Max 12V VDD-VSS
