ADS1115BQDGSRQ1 in TI ADS1115 / ADS1118 ADC Family
The ADS1115BQDGSRQ1 family by Texas Instruments consists of high-precision, automotive-qualified 16-bit analog-to-digital converters designed for space-constrained applications requiring high-resolution measurement. These devices utilize a Delta-Sigma architecture and feature an integrated voltage reference, oscillator, and a programmable gain amplifier. Primarily used for monitoring sensor signals in automotive environments, they provide reliable data conversion over the AEC-Q100 Grade 1 temperature range, ensuring robust performance in electrically noisy systems.
Variants in This Sub-Family
Variants within this sub-family primarily differ based on their automotive qualification levels and packaging options. While the core 16-bit Delta-Sigma engine remains consistent, specific part numbers denote differences in temperature grade support (Grade 1 vs Grade 2) and package types like VSSOP or ultra-small X2QFN. Some related variants may trade resolution for speed, such as the 12-bit ADS1015 series.
