Technical Details & Description

8-bit SAR ADC with 1 MSPS throughput

The Texas Instruments ADS7040IDCUT is an 8-bit successive-approximation-register (SAR) ADC that samples at 1 MSPS. It accepts a single-ended input and communicates over an SPI bus, making it a straightforward fit for microcontrollers that lack an integrated ADC or need an extra dedicated conversion channel.

Single-supply range and temperature grade

Both the analog and digital supply rails share the same 1.65 V to 3.6 V range, so the ADC runs off a single supply without needing a separate reference or a higher-voltage analog rail. The 8-VSSOP package (2.30 mm width) keeps the PCB footprint small, which helps when routing the single-ended input close to the sensor without long traces that pick up noise.

Frequently asked questions

What is the closest functional second-source for the ADS7040IDCUT?

The ADS7887SDCKT is a close peer — it is also a single-ended SAR ADC with SPI interface in a similar package, but it offers 10-bit resolution and a slightly higher sampling rate of 1.25 MSPS. Pin compatibility should be verified against the respective datasheets before substitution.

What compliance documentation does Texas Instruments provide for the ADS7040IDCUT?

Texas Instruments provides RoHS3 compliance certification for the ADS7040IDCUT. Standard documentation includes the datasheet and RoHS declaration. No UL or IEC certification is listed in the available records.
