See all from this product rangeProduct Overview
The DDC114IRTCT is a 20-bit quad channel current-input Analog-to-digital Converter (ADC) combines both current-to-voltage and A/D conversion so that four low-level current output devices, such as photodiodes can be directly connected to its inputs and digitized. For each of the four inputs, the DDC114 provides a dual-switched integrator front-end. This design allows for continuous current integration: while one integrator is being digitized by the on board A/D converter, the other is integrating the input current. Adjustable full-scale ranges from 12 to 350pC and adjustable integration times from 50µs to 1s allow currents from fAs to µAs to be measured with outstanding precision. Low-level linearity is ±0.5ppm of the full-scale range and noise is 5.2ppm of the full-scale range. Two modes of operation are provided. In low-power mode, total power dissipation is only 13.5mW per channel with a maximum data rate of 2.5kSPS.
- Single-chip solution to directly measure four low-level currents
- High precision, true integrating function
- Integral linearity
- Programmable full scale
