The Analog Devices ADUM1201CRZ digital isolator, available now from WIN SOURCE, is a vital component in this series of low-power, high-performance digital isolators. This isolator uses an advanced RISC architecture, capable of executing most instructions in a single clock cycle, delivering throughputs close to 1MIPS/MHz. This efficiency enables applications to balance power consumption with processing speed effectively.
The isolator offers an impressive array of features, including two independent isolation channels operating across various channel configurations and data rates. Both devices support a supply voltage from 2.7V to 5.5V, compatible with low-voltage systems while attaining voltage conversion across isolation barriers. Moreover, the device provides extremely low pulse width distortion (less than 3ns for CR grade) and tight inter-channel matching (less than 3ns for CR grade). Unlike other optocoupler alternatives, the isolator possesses a patented refresh feature, providing DC correctness in the absence of input logic transitions and power supply fluctuations.
Operating voltages range from 1.8V to 5.5V, with a temperature range from -40C to 85C, ensuring adaptability to varied operating environments. The device's peripheral capabilities are extensive, including two 8-bit and one 16-bit timer/counters, a real-time counter, six PWM channels, and an 8-channel 10-bit ADC in specific packages. Connectivity is enabled through a programmable serial USART, master/slave SPI serial interface, and a byte-oriented 2-wire serial interface compatible with Philips I2C, ensuring diverse communication options.
The isolator's low power consumption is especially noteworthy. It features modes designed to minimise energy consumption while maintaining functionality, making it excellent for battery-powered and portable devices. Its internal calibrated oscillator improves system reliability by supplying a ready-to-use clock, decreasing the necessity for external components.
The isolator suits various applications, from consumer electronics to complex industrial controls. Its support for capacitive touch interfaces opens doors to innovative user interaction possibilities in home automation systems, personal gadgets, and industrial interfaces.
