Part Number: BUF12840 Other Parts Discussed in Thread: BUF16821 Dear, Sir.
My customer is evaluating BUF12840. At this time, I would like to make sure about
output source/sink current. Please give your advice.
They are using 1ch output under 104mA source…
Part Number: BUF12840 Dear, Sir.
My customer is considering the DAC OUTx control by VS OFF/ON.
- VSD(Digital supply) is applied always. So not related to POR.
- DAC OUTx outputs based on the internal resister setting, not 0V.
- DAC OUTx will be controlled…
Part Number: BUF12840 Hi, Team,
For BANK1 non-use pin configuration, is it ok to input FFh for both MSB and LSB when BUF12840 read EEPROM at the start up? The IC is 10 bit, but the customer set all 1 including the upper 6bit.
Configuration BKSEL pin：0V…
Part Number: BUF12840 Hi Team,
My customer is considering to use BUF12840 and they are evaluating in the now. When the output voltage of BUF12840 was measured, In the result OUT0 / OUT11 a voltage error larger than other pin error. It is an error within…
Other Parts Discussed in Thread: BUF12840 Hi
Do you have answer for the following questions?
We are about to have 50uF or larger capacitance at DAC out6.
What kind of bad influence is expected?
Are there recommended value of output capacitance?
Best…
Other Parts Discussed in Thread: BUF12840 Hi
We are looking for a gamma buffer with internal eeprom (memory).
It is better if the gamma buffer has similar function as BUF12840 .
Do you have such devices?

Other Parts Discussed in Thread: BUF12840 , BUF18830 Hi! all,
My customer plans to use BUF12840 as LDC gamma buffer. And OUT6 is planned to use as VCOM. They want to add large capacitor for stabilizing its output level as below.
Is there any problem about…
Other Parts Discussed in Thread: BUF12840 Dear Sir,
I am going to design LCD gamma buffer and looking for a reference design circuit.
could you please share BUF12840 reference design for me , Thanks.
It is my honor to have your reply.
