TPS7B83-Q1: TPS7B83 , ADS1100 , INA190

Part Number: TPS7B83-Q1
Other Parts Discussed in Thread: ADS1100, INA190

Hi all,

We are intended to use the following chips in one of out circuit design 

  • TPS7B83 150-mA, 40-V, Low-Dropout Regulator.
  • ADS1100 Self-Calibrating, 16-Bit ANALOG-TO-DIGITAL CONVERTER.
  •  INA190 Bidirectional, Low-Power, Zero-Drift, Wide Dynamic Range, Precision Current-Sense Amplifier With Enable.

Can you please provided us any information on how these chips can be mounted to breadboard or PCB or any other way to form a complete circuit.

If there is any PCB which can accommodate these chips please do recommend us.

The below image is for reference.

    Hi Kaushik, 

    For TPS7B83 in DCY, I would suggest getting one of the universal EVM, before you try to connect it through breadboard as the LDO requires input and output capacitors close to the pins.

    thanks for the information, what are the mounting options that can be implemented for these three chips? 

    and which one is more feasible?

    Kaushik,

    For the INA190, an easyt way to get one of these devices onto a breadboard would be to sample the device in a leaded package (SOT23-8 or SC70-6), and then use a quick adapter for this style of package. For example, there is one available for SC70-6 on Digi-key here. Make sure that when you do use an adapter such as this that the pitch matches the pins. Here is the package data for the SC70-6 package from the INA190 datasheet:

    As Jason mentions for his LDO, ensure that recommendations in the datasheet are followed via the breadboard (decoupling cap on Vs, etc.) if you plan to do this. 

    The ADS1100 is going to be the challenge here. I am looping in the ADC team to give their recommendations on this, but for a device this complex, I believe EVM will most likely be their recommendation here.

    Hello,

    The ADS1100 does not have an EVM, but it has a simple SOT23 package. there is a DIY EVM board TI offers that can be used to support this device. the DIY EVM provides socked boards in SOT23 and other footprint with spaces for decaps and header or SMA connections.
