Part Number: OPA4344 The Rtheta JA is provided in the datasheet but the Theta_JC is not provided. Please provide Rtheta JC for the OPA4344EA TSSOP14 package
Other Parts Discussed in Thread: OPA4344 Hi All,
Our customer has evaluated OPA4344 at feedback circuit of AC/DC converter as attached. But the output of OPA4344 is uncontrolled suddenly though we have not found any trigger of this behavior. On the…
Other Parts Discussed in Thread: OPA4344 Hi,
Our customer has understood about the behavior/specification of OPAx344 as following description.
It seems they referred "Fig.2 - Simplified schematic" on the datasheet -page9.
- OPAx344 has 3…
Hi Marek,
Thank you for your response.
It's OK if the minimum VCMR is still -0.3V at over temperature range. The reason why our customer has cared it is they are using OPA4344 with 5V single supply operation and +IIN is below to 0V, so they concern…
Hello Ray,
I agree with Kai's suggestion of devices.
The specifications for a quad channel amplifier with sub 2 pA max input bias current may limit the options considerably.( Link Here )
I have included a device comparison table below for some…
The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
