Semiconductors\Data Converter ICs\Analog Front End - AFE
ADS131A0x Analog Front-End ICsTexas Instruments ADS131A0x Analog Front-End ICs are two or four-channel, simultaneously-sampling, 24-bit, delta-sigma (ΔΣ), analog-to-digital converters (ADCs). The wide dynamic range, scalable data rates, and internal fault monitors make these devices ideal for energy monitoring, protection, and control applications. The ADC inputs can be independently and directly interfaced with a resistor-divider network, a transformer to measure voltage or current, or a Rogowski coil to measure current. Flexible power supply options, including an internal negative charge pump, are available to maximize the effective number of bits (ENOB) for high dynamic range applications. The Texas Instruments ADS131A0x support data rates up to 128kSPS. The complete analog front-end (AFE) solutions are packaged in a 32-pin TQFP package and are specified over the industrial temperature range of –40°C to +125°C.
