OPA2156: OPA2156 alternative pn

Hi Nicolas,

depends on what you need. What is wrong with the OPA2156 and what do you wish to get instead? What parameters are important for you and which specifications do you need?

Kai

You mean a dual in SOT23-5? Very unlikely to find one anywhere. How about the OPA1678? 

Hello Kai, thanks for the reply.
These are the specs:

• VCC>15V (single supply)
• OP rail input (at least +Vcc) and rail output (at least VoH) (it works around +Vcc)
• GBW > 1MHz
• SR > 2V/µs
• Ts < 1 µs
• Vos (max) < 1mV
• Ib (max) < 200nA
• Single Opa, dual could be nice for other application aswell
• Recommended for new projects
• Not high price

BR,
Nicolas

Hi Nicolas,

that's what I have found so far:

Please still check out the settling times :-)
