3. CAN and DAC technologies

The data conversion market has grown considerably in recent years. The demands placed on converters, in terms of performance, cost and size, have led manufacturers and academics to study new architectures and specific technologies. Today, CAN/CNAs are built on a single chip (monolithic technology). They benefit from the advantages of advanced integration, i.e. increased density and speed, and lower power consumption. Today, many CAN/CNAs are true systems that include just about everything analog (multiplexers, sample-and-hold, etc.), but also digital with signal processing (error correction, averaging, calibration, programming interface). They often use a single supply voltage of 3.3 to 1.8 V.

Some circuits keep higher voltages to accept 5, 10 and ± 10 V analog signals, which are widely used in the industrial world.

As with all components,...
