ADS1230IPWR SMD IC ADC 20 BIT TSSOP16 ADS1230IPWR

Product Overview:
A surface-mount, 20-bit analog-to-digital converter (ADC) integrated circuit designed as a complete front-end solution for bridge sensors in high-precision measurement applications. It integrates an onboard low-noise programmable gain amplifier (PGA), a precision delta-sigma ADC core, and an onboard oscillator to simplify system layout and eliminate external components in industrial weighing or pressure-sensing designs.
