Part Number: LM2766 Other Parts Discussed in Thread: OPA2170 , , TLV2402 Hello!
I am using LM2766 with 3.3V input and 6.6V output. It only powers a dual amplifier, OPA2170 (about 250 uA total current).
LM2766 has an enable signal, which should be used to…
Part Number: SN74CB3Q3306A Other Parts Discussed in Thread: OPA2170 HI All,
May I know whether we have the Θjc or Ψjt of SN74CB3Q3306A DCU R?

Hi Tim,
I use now the OPA2170 with the 8 pin VSSOP. I will change it due to more output current ability of the OPA2990 (80mA/-80mA at OPA2990 against to 17mA/-20mA at OPA2170) without need to change also the PCB.
Thank you
George
Hi Toon,
For a high voltage voltage-follower, you could choose a newer CMOS op-amp like the OPA2170 or TLV2170. The TL062 might also be a good choice.
Hope that helps,
Paul
Hello,
Here's a link to a good design guide for non-inverting amplifier circuits. The LMC662 is a good amp but there are much newer alternatives which perform better for lower costs.
For +1.8V - 5.5V supplies look at the TLV9002 (1MHz) or TLV9062…
Hi Marek,
thanks for your reply. Actually the common mode range for linear operation of INA333 is around 1.6 - 1.7V if I want to have the output range up to 3V (by the way: 3V is the reference voltage of the ADC). But in the measurement data that you…
Hi Richard,
I think you can replace the TLC072 with a newer, lower cost op amp, the OPA2170. It provides good dc performance, and Vo when sinking 1 mA is rated at 70 mV max, at 25 C. Its quiescent current is typically only 110 uA and thus, it isn't a…
