What is it?

This is an 8-channel 12-bit ADC module featuring the ADS7038 from TI. The ADS7038 IC uses SPI communication. This board breaks out all the SPI pins into 0.1" headers, as well as a custom JST SH connector. The breakout has all of the ADC input channels broken out into a 2x10 connector (8 ADC inputs + power and ground). The signals are connected to both rows, allowing for easy debugging and connections from the load.

Features

The ADS7038 from TI is featured packed! - It has 8 analog input channel but they can be configured as analog inputs, digital inputs or even digital outputs!

• The GPIO's can be configured as open-drain or push-pull digital outputs
• It has an enhanced SPI digital interface.
• It comes with an internal reference.
• Each analog input has 12-bit resolution.
• It has programmable filters and has analog watchdog which can be configured as interrupts.
• Its a SAR ADC with 1MSPS speed!
• Perfect for both 3.3V and 5V systems.

Each analog input has an RC filter (10Ohm / 1nF), providing filter and input protection.

The IC is bypassed with 1uF and 0.1uF capacitors.

Soldering is required for this module. The header pins will come with the board and will need to be soldered.

Why did you make it?

I didn't find a simple breakout for the ADS7038 IC at the price point I was looking for. Also, I wanted plenty of points to be able to probe, which is why I included 2 sets of IC communication connectors and also a dual row 10-pin connector for the analog inputs (which includes VCC and GND pins), this allows one pin to be used to apply an external voltage and pin for monitoring (making it very easy to debug).

This board can be used for anyone looking to develop software using the ADS7038 IC or for a simple 8-channel ADC IC.

What makes it special?

All parts are genuine and of good quality. The board is built in the USA!
