Part Number: OPA857
Hi,
As our design evolves and OPA857 is a selected candidtae for our TIA, I need more details about some parameters that are specified with few details:
It seems that per data sheet, the chip Tz and BW are stable with temperature, however the values of these parameters are given as typical only. Hence some questions:
1. What is the tolerance of the chip BW?
2. What is the impact of the Tz tolerance (+/-15%) on the chip BW?
3. What is the tolerance of the Rout of 25ohms?
4. We need 3 chips in a 3 channel amplifier and therefore the Tz, BW and Rout of the 3 OPA587 need to be closely matched. What is your recommendation for this? Can TI provide chips binned in matched triplets? Any other suggestion is greatly appreciated.
Thank you,
Marcela
