ADS1247IPWR in TI ADS1115 / ADS1118 ADC Family
The ADS1247IPWR belongs to a family of high-precision, 24-bit delta-sigma analog-to-digital converters (ADCs) manufactured by Texas Instruments. Designed for high-accuracy sensor measurement, these devices integrate a low-noise programmable gain amplifier, a precision voltage reference, and an internal oscillator. This family is engineered to simplify the interfacing of bridge sensors, thermocouples, and resistance temperature detectors (RTDs) in demanding industrial environments where signal integrity and noise rejection are critical requirements.
Variants in This Sub-Family
Variants within this sub-family primarily differ in channel count and integrated peripheral sets. While the ADS1247 provides four analog inputs, the ADS1248 expands this to eight inputs for higher density applications. Other differences include the presence of integrated IDACs for sensor excitation and specific packaging options like TSSOP versus VQFN, which impact thermal performance and footprint in compact PCB designs.
