Analog Front End

ADS1198CPAG Description

The ADS1198CPAG from Texas Instruments is a high-performance, 16-bit, 8-channel analog front-end (AFE) designed for precision data acquisition in medical, industrial, and instrumentation applications. Housed in a 64-TQFP package, this IC integrates a low-noise programmable gain amplifier (PGA), a high-resolution delta-sigma ADC, and flexible digital interfaces. It operates with dual supply voltages (1.65V–3.6V digital, 2.7V–5.25V analog), ensuring compatibility with diverse system designs while consuming just 8.2 mW of power. The device is ROHS3 compliant, REACH unaffected, and rated for MSL 3 (168 hours), making it suitable for environmentally conscious and reliability-focused applications.

ADS1198CPAG Features

• 16-Bit Resolution: Delivers high-accuracy signal conversion for sensitive measurements.
• 8-Channel Input: Supports simultaneous multi-channel data acquisition, ideal for EEG/ECG systems.
• Low Power Consumption: Optimized for battery-powered portable devices (8.2 mW typical).
• Flexible Supply Rails: Independent analog (2.7V–5.25V) and digital (1.65V–3.6V) supplies enhance design versatility.
• Integrated PGA: Programmable gain (1–12) improves dynamic range for low-amplitude signals.
• Robust Compliance: Meets ROHS3, REACH, and EAR99 standards for global deployment.
• Surface-Mount TQFP Package: Compact footprint (64-pin) suits space-constrained PCBs.
