Part Number: OPT3007

Hi,

I have a customer with questions on following:

1. PSRR requirements? <dB and frequency>

2. Integrated noise requirements at Vout?

Thanks,

Hi Chuchen,

PSRR is spec'd in the datasheet at .1% change in measured lux output from its current value divided by the change in power supply voltage (tested at 1.6 and 3.3V). Since the device outputs in lux this cannot be expressed as a db V/V ratio.

Would you be able to provide some more details on what the customer is looking for. It sounds like they want to know if the device will function with their supply. Do you happen to know the noise characteristics of their supply?

Best,

Alex
