ADS1148IPW TI ADC | 28-TSSOP | 16-Bit, 2kSPS, Low-Power

Product Overview

The ADS1148IPW is a precision, 16-bit, delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features an integrated programmable gain amplifier (PGA), voltage reference, and oscillator, making it a complete front-end solution for low-power, high-precision measurement applications. Housed in a compact 28-TSSOP package, it operates from a 2.7V to 5.5V supply and consumes only 2.3mW, ideal for battery-powered systems.
