Part Number: OPA521 Good day!
I would use OPA521 for a low noise, high current DC design. Basically, I would use it as an inverting input OP-AMP. Could dual supply (+/-12V) be used for the chip?
By TINA simulation, it looks fine. Anything to watch out…
Part Number: OPA521 Hi,
According to the datasheet, the enable and disable times for OPA521 are 3 and 2 milliseconds respectively. This would be far too slow for my application.
However, measuring on the EVM gives me a value of about 31 micro seconds for…

Hi Team
We have tested the OPA521 Line Driver, and the main problems are as follows:
1:In FCC band (150 KHZ to 500 KHZ) cases, the load resistance is 2 Ω, PA distortion is very serious.…
Part Number: OPA521 Other Parts Discussed in Thread: OPA564 Hello team,
Can OPA521 work with unity gain if phase compensation is properly done externally and if GAIN_SET pin and -IN pin are shorted? If it is feasible, what is common mode voltage range? …
Hi Raymond,
The signal to be fed into OPA521 is a combination of a PWM and a signal from UART, both generated by an MCU. The PWM is 50% duty ratio with frequency of 88KHz, and the signal from UART is a series of byte data in RS232 protocol (1 start bit…

I was hoping to get some help selecting an alternative solution for the OPA593, the proposed application…
Part Number: OPA564 Other Parts Discussed in Thread: AFE030 , OPA521 , AFE031 , AFE032 In the OPA564 datasheet there is Figure 58 entitled "Detailed Powerline Communication Circuit" but there is no additional detailed information about the circuit in the…
Hi Vidya,
Adding Michael's comment.
We have OPA521 (BW = 3.2MHz) power amplifiers that have many similarity with OPA561 (except the BW). Although it is advertised as Powerline line driver (for marketing reasons), it may be suited for the application…
Part Number: AFE031 Other Parts Discussed in Thread: THS6222 , , OPA2670 , OPA521 , OPA564 , AFE030 , AFE032 Hi team,
May I ask that what is the different application scenarios between AFE031 and THS6222.
I see AFE031 is the AFE for PLC, THS6222 is the PLC…
Hi Ping,
Do you have any good suggestions on current sharing?
Thanks Kai for the links for paralleling op amps to boost the output current.
I normally do not like to use the method to boost the op amp's current. Could you share the design requirements…
