Part Number: ADC3644 Other Parts Discussed in Thread: OPA837 , , REF3318 Hi team,
In the EVM of ADC3644, 1.6V of VREF is divided and supplied by REF3318 and OPA837. Is this because there was no 1.6V reference? If I use the ADC3644 with an external reference…
Part Number: REF3318 Hello team,
Hope you are well.
Customer is inquiring about any baking instructions for MSL2 parts such as REF3318AIDCK?
There were parts which were left in open stock and would like to have them properly dried.
Regards,
Randhir
Part Number: ADC3663EVM Other Parts Discussed in Thread: ADC3663 , OPA837 , REF3318 , LMK04828 Hello,
I`m trying to replicate one of the figures of the ADC3663 datasheet, to be sure my setup is right. Concretely, I'm trying to replicate figure 6-40, Single…
Part Number: LM27762 Other Parts Discussed in Thread: INA821 , REF5050 , REF3318 , , TPS7A39
Based on my device it needs to be low noise between 0.1-20Hz. My +-5v is mainly for the ina821 instrumentation amplifier, which has a PSRR of 120db.

Part Number: AM3358 Other Parts Discussed in Thread: TLVH431 , REF3318
Hello, looking through AM335x voltage rail clamp between 1.8V and 3.3V rail documented in figure 7 of slvu731b, the default design uses 5 parts including the shunt voltage reference…
Part Number: TMDSHVMTRPFCKIT Dear team:
If the AD sampling range is from 0V to 3.3V, then the median value should be 1.65V. Why use 1.8V reference source to participate in the calculation in this circuit?
As shown in U2 in the figure above, REF3318 is…
Hi TER,
The current through P0_7 is -61uA (minus 61uA) in both PM1 and PM2. Is quite rare because current meter red probe is connected to the REF3318 output and black probe connected to P0_7... this means that REF3318 is sink 61uA...
Hi SeaFesse,
If you need exactly 0.9V then I would use a REF3318 (1.8V VREF) and voltage divide by 1/2 and then use a buffer to ensure that there is minimal IR loss. the same technique can be used for a 0.8V device. The buffer requirements are very low…
Hi Sourabh,
It is possible to lower the output of the REF5020 by using the TRIM/NR pin.
Another device is the REF3318. While it doesn't mean all the specs, it is close.
Shunt references are too noisy and inaccurate for this ADC application. Typically…
