ADS131E0x Analog Front End

Texas Instruments' multi-channel, multi-bit analog front end for energy applications

Image of Texas Instruments' ADS131E0x Analog Front EndTexas Instruments' ADS131E0X family represents the best combination of overall performance and price per channel offered in the market. Performance features include an SNR of 103 dB, THfD of -101 dB, input range of ±2.4 V/gain, reference accuracy of 0.2% and supply options of either 3 or 5 V.

The ADS131E0X family is targeted for the mid- to high-end e-meter equipment markets. The family enables the flexibility for end-customers to create and implement their own algorithms - a key feature valued in the high-end markets, as well as some mid-tier markets.

Features
  • Low power: 2 mW per channel
  • Data rates: 1, 2, 4, 8, 16, 32, and 64 kSPS
  • Programmable gains (1, 2, 4, 8, and 12)
  • Fault detection and device testing capability
  • SPI™ data interface and four GPIOs
Applications
  • Energy metering
  • Monitoring, control, and protection
