Hi all,
We are getting latch-up in the AD7376ARWZ10 digital pot which we run off +/-15V supplies.
There are short periods (200ms) where the VDD & VSS (+/-15V) supplies are not powered fully and yet signals are being input to the device : either 5 V…
I was looking for a replacement to LDR based potentiometers in a tube amplifier and found the AD7376 1M poti on google,
On your website there is only a version up to 100K available.
My question is now whether there is a 1M version of this digital pot…
Hello,
Trying to figure out why the accuracy of the AD7376 is so poor at the lower end of the scale compared to the higher end.
I have the device set up as a voltage divider as shown in the schematic below:
The +5V_OUTPUT net is referenced to the GND…
I'm reading the datasheet for the AD7376 and it says the following:
Because of the ESD protection diodes that limit the voltage compliance at Terminals A, B, and W (see Figure 30), it is important to power VDD/VSS before applying voltage to Terminals…
Hi EngineerZone members,
I am using AD7367 eval kits AD7367CBZ, Rev A along with controller board EVAl-CONTROL_BRD2 Rev C. Using the eval software i am able to read the data on PC. However I want to log the data continuously on PC. Given software GUI…
Please share the schematic.
There are certain application notes or details available here related to zipper noise.

Hi Miguel,
We had understood teminal A is disconnected when Shutdown. What we do NOT understand is reason why it result to improve signal attenuation at audio application.
I found Audio Volume Control with Zipper Noise reduction in the datasheet of…
Hi, I used yours AD5290 as volume control in a power amplifier.
I already have used your AD7376 in an old project and I connected the SPI link to the +15V by means of a pullup resistor..
When I used the AD5290 I also conncted the SPI to the +15V with…
