Hai ,Can any one suggest an ic to generate negative reference voltage for AD5545 to get positive o/p voltage from DAC of range 0 to 5V.
May I know why you choose the AD5545? What is the application for the DAC you are going to use?
If you only want to get an output of 0-5V, you can use AD5689R which does not need an external amplifier.
To answer your question, you have two options as we do not currently have a negative reference device:
1) Use a positive reference in this configuration to create a negative potential on VREF
2) add another opamp after the transimpedance amplifier to act as an inverter.
Thanks for the reply
1)May I know why you choose the AD5545?
In my design i need to generate two adjustable tuning voltages(0V TO 5V) for camera detector which draws less than 1mA of current and he recommended input to be very less noisy.
so i have chosen AD5545 which has relatively less noise compared to all other types of DAC'S.
if available suggest me an DAC better than AD5545 .
Have you taken a look at the AD5441A?
Nice to talk to you again
I need an analog Catalog offline Application in which i should get all the available analog products as well as application notes design notes and tutorials etc..
can you please provide the link to download the same.
You can find them here.
