Is there a pin-compatible replacement for ADS1015IDGSR?

Yes, the Texas Instruments ADS1115 family (e.g., ADS1115IDGSR) shares the same VSSOP-10 package and pinout. It is a potential drop-in replacement if the application can tolerate a lower sampling speed.

What risks should I check before replacing ADS1015IDGSR?

The main risk is the reduced sampling rate when moving to the 16-bit ADS1115 (860 SPS vs. 3.3 kSPS). Also, verify I2C timing and register settings, as firmware adjustments may be needed to utilize the higher resolution.

ADS1015IDGSR Alternatives, Datasheet & Cross Reference | Texas Instruments

The ADS1015IDGSR is a popular 12-bit I2C ADC from Texas Instruments. Common alternatives like the ADS1115 offer a pin-compatible upgrade to 16-bit resolution but require careful review of the lower sampling rate.

AI replacement insight

Firmware riskmedium

Firmware must be updated to handle 16-bit data and potentially different I2C register configurations.

Electrical risklow

Voltage, interface, and temperature ranges are compatible.

Package risklow

The VSSOP-10 package and pinout are compatible.

Can it be replaced directly?

The ADS1115IDGSR is a potential pin-compatible replacement, but it is not a direct drop-in due to the different sampling rate and resolution, which may require firmware changes.

Best replacement path

Upgrade to ADS1115IDGSR for higher resolution, if the lower sampling rate of 860 SPS is acceptable for the application.

Main risk

The primary risk is the significant reduction in maximum sampling rate from 3.3 kSPS to 860 SPS.

Recommended alternatives

A common upgrade for higher resolution, this 16-bit ADC is pin-compatible but has a lower maximum sample rate.
