Part Number: OPA2156
Other Parts Discussed in Thread: OPA1678

Hello,

Are there alternatives to OPA2156?
What about alternatives to OPA2156 with package sot23-5?

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?

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
