ADS1220IPWR in TI ADS1115 / ADS1118 ADC Family
The ADS1220 series by Texas Instruments represents a specialized family of high-precision, 24-bit delta-sigma analog-to-digital converters designed for demanding sensor measurement tasks. Featuring an integrated low-noise programmable gain amplifier, dual programmable current sources, and a precision voltage reference, these components are optimized for small-signal measurements. They are commonly utilized by engineers to interface with RTDs, thermocouples, and bridge sensors in industrial automation and portable instrumentation where board space and power efficiency are critical constraints.
Variants in This Sub-Family
Variants within this sub-family primarily differ in interface options, package types, and bit resolution. While the ADS1220 offers a 24-bit SPI interface, related siblings like the ADS1120 provide 16-bit resolution for lower-cost requirements. Package options range from the standard 16-pin TSSOP to ultra-small VQFN footprints. Some specialized variants may also offer I2C communication instead of SPI to accommodate different microcontroller bus architectures.
