The DDC118IRTCT from Texas Instruments is an octal, current-input, 20-bit analog-to-digital converter designed for high-precision measurements. It integrates current-to-voltage conversion and A/D conversion, allowing direct connection of eight low-level current output devices like photodiodes.
Key electrical specifications include a 20-bit resolution, an SPI serial interface, and an operating voltage range of 2.7V to 5.25V. The device features a Sigma-Delta architecture and offers a sampling rate of up to 3.125kSPS. It boasts high precision with integral linearity of ±0.01% of reading and ±0.5ppm of FSR, and very low noise at 5.2ppm of FSR. The power consumption is rated at 13.5mW per channel.
This converter supports adjustable full-scale ranges from 12pC to 350pC and adjustable integration times from 50µs to 1s, enabling the measurement of currents from fAs to µAs. The operating temperature range is -40°C to 85°C.
The DDC118IRTCT is available in a 48-VQFN (7x7) surface-mount package (48-VFQFN Exposed Pad). Its design is suitable for applications requiring direct measurement of low-level currents, such as CT scanners, DAS, photodiode sensors, infrared pyrometers, and liquid/gas chromatography.
