This application note introduces the components and measurement techniques for 16-bit data converters. It provides a new perspective and methods for the design of 16-bit data converters.
The document addresses the challenges of measuring settling time in 16-bit digital-to-analog converters (DACs), noting that dynamic measurements to this resolution are particularly difficult. It explains that standard measurement techniques often fail due to oscilloscope overdrive issues when dealing with high-speed transitions and small error bands.
The settling time is usually specified for a full-scale 10V transition.
The amplifiers shown contribute less than 1LSB error over 0 °C to 70°C with 16-bit DAC driven settling times of 1.7 µs available.
The gain drift is typically 1ppm/ °C or about 2LSBs over 0 °C to 70°C.
