Hi ,

I Have a question about enable ADN8834.

I put a TEC of 2,5Ohm resistor between TEC_P & TEC_N.

I control the ADN8834 with a DAC by default 1,25 V so output it's 0V.

But when I enable the ADN8834 by EN/SY ( all V power, V ref are good) I have…

I have a question on the Vout2. What  is the voltage on  Vout2 when the object temperature equals to the target temperature? It is described on Page 19 on the Datasheet.

Vout2 = Vtempset - (Z2/Z1)(Vout1 - Vtempset)

When the object temperature equals to…

Dear Sir/Madam,

I have a question about ADN8834, in the Datasheet there is a typical application circuit on Page 14, as shown below

I want to know what the function of the two resistors.  What is the meaning that get the Vref/2? If I would like to contol the temprature…

Hi,

I am using AND8834 for a TEC module, and I have two questions ( forgive my English, I am Chinese) :

1) Based on formulas given in DS, I have following conclusions:

     Vout2 = Vtempset - Z2 / Z1 ( Vout1 - Vtempset )

     Vtec = VLDR - VSFB = - 5 ( Vout2…

Hi 

I tested ADN8834.

I set IN2P 0 to 3.3V and out2 changed 0 to 2.5V (out1 only 3.3V)

but LDR and SFB is strange

this is my result.

(TEC+ = LDR,  TEC- = SFB)

why SFB is not bigger then LDR?

This is my schematic. 

Thank you for reading. and…

Hi

My custmer try to use ADN8834.

The TEC voltage and the upper limit of the electric current are being designed by 1.0V/1.5A respectively.

In DS, Recommended Inductors

My custmer try to use ,

Vender:TDK

Value:2.2uH ±30%　2.62A（Typ）

Device No…

Hallo,

are the two chopper stabilized amplifers inside the ADN8834 on while the chip is in standby. I plan implementing a digital control loop arournd the AD8834. It want to use one of the amplifiers for buffering the voltage across the thermistor. But…
