Yes. ADP7182 can be used as current source. 


Re: Setting up a Custom Profile for LTE20MHz using IIO Oscilloscope in AD9371

Hi Rejeesh,

I tried to update JESD, XCVR IP cores and IP cores and compiled a rbf file.

I also generated a uboot_w_dtb-mkpimage.bin based on instructions on Altera SOC Quick Start Guide [Analog Devices Wiki] 

I also updated ad9371.c with the setting based on the matlab filter wizard. For devicetree, I have modifed dts file (see attached file) and then using dtc script back to dtb and I am seeing the following error:

 

root@analog:~# [  131.991600] altera_xcvr ff220000.xcvr_core: RX transceiver NOT ready [00fc]

Can you help take a look at the settings?

Hi,

 

I have a problem with PLL design software. Instalation is succesful, but problem is with MCR.

 

I have Matlab 2011, so i try instal new version 2015, problem still alive (picture PLL1.png)

 

 I found in forum on EngineerZone at https://ez.analog.com/welcome installer:  MCRInstaller7p11.exe If I install it, there is no error message. After turn on PLL Design there is only picture (PLL2.png) and after program is turn off.

 

Thanks for your help,

I'd like to setup SW to use AD9361 DUAL PORT FULL DUPLEX MODE (CMOS). How to setup AD9361_InitParam default_init_param?

 

I captured the default setup from eval software.

ADL5315 Voltage measure and current control

$

I have a question about ADL5315.

I'm looking at the voltage to current converting (BIAS CONTROL INTERFACE, Datasheet Page 10)

 

I will measure the sensor voltage and control the current.

If measured sensor voltage is higher than VSET, control the current to be lower.

If measured sensor voltage is lower than VSET, control the current to be higher.

 

Question :

1. Can it be possible to control the Iout current by measuring sensor voltage?

2. How to expect IOUT current with regard to VSET?

3. Could I connect IOUT to the load to supply current?

4. In this condition, How to connect SREF pin?

Re: AD7124-4 Noise Performance

Hi,

 

1. It is necessary to apply a bias voltage so that the inputs are at a certain fixed voltage level to ensure that the common mode voltage level of the signal is within the acceptable input range.

2. Biasing at mid supply is an appropriate voltage level for noise test as amplifiers tends to perform better when their outputs are far away from the rails. Thus, AD7124 noise specifications are also tested with internal VBIAS enabled.

3. There's nothing much difference as long as both inputs are tied together, you can enable the biased voltage on either or both of the inputs.

 

Thanks,

Jellenie

EVAL-ADV739x Register Control Problem

$

Hi,

    I use the ATV Benchtop software to control the EVAL-ADV739x board, AD7403_xc3s400_adv7391-VER.1.2.c. I choose the setting of ##SD## : AUTODETECT NTSC/PAL/SECAM 10-Bit 422 out through encoder. I found some of the value of register is not as same as it in the **.txt. And some of the registers have two same address but different value.

 

In the  **.txt the value of address 52 is 0x46, but it shows 0xC8. There are two address 98, address 99 .... One is read only, another is write only. I write a new value to the write only one, and then read the read only one, the value is not the value which is I write. So why ?

FMCDAQ2 lanes configuration

why are these lanes crossed like that? do I need to keep them that way? when connecting additional channels do I need to follow this convention? thanks!

 

Re: If i use a AVdd of 5V and buffer on(ADuC7122) or external reference (ADuC7023) , then can i use signals with 5V input to ADC pins as well as output of 5V from DAC pins.

The ADuC7x2x products are rated to survive the max. rating and GPIOs can be used with external pull-up's to work on 5V I/Os. But the parts are only qualified/specified to work in a range of 2.7V to 3.6V. Outside this range the detailed parameters are not guaranteed.

I've branched this into a new thread because the first questions from the old one were already answered and these new ones are somehow not related to them.

AD7924 SPI error

$

Hi guys.

I bought a little AD7924.

 

I tried to use it, but it did not work well.

 

Several experiments have shown that the CSB and DIN (MOSI) of the SPI interface are reversed from the datasheet.

 

I would like to know if the AD7924 I purchased is faked or defective.

 

The chip is marked as follows.

7924

BRUZ

# 551

 

Please answer.

As specified in the datasheet the recommended input range for all analog inputs is 0.1V to AVDD with max. ratings given from -0.3 V to AVDD + 0.3 V.

Re: ADT7420 reportable temperature range

Hi,

 

A code will be output, but its accuracy will degrade considerably. Note the package and lead frame on ADT7420 is different that the used on ADT7310, so this part is not specified to down to that temperature.

 

Is your application working down to that temperature range (-55C to -40C) normally? What the reason for upgrading, what's your accuracy needs?

 

Thanks,

Lluis.

Re: ADT7420 reportable temperature range

It will theoretically be working down to -50/-55, but it's not going to happen very often.  An accuracy of +/-0.25 to 0.5 degrees Celcius below -40 would be nice.  I've been unable to find any informaiton on accuracy degradation below -40 on the ADT7420.

This is for a new product.  Currently we're going to fit the ADT7410 which has a lower operating range (-55), but we would like the smaller footprint and higher accuracy of the ADT7420.
