“Precision sensing requires a low noise, high resolution signal conversion architecture,” said Mike Britchfield, product line director, Precision Signal Processing, Analog Devices. “With its on-chip 24-bit sigma-delta ADCs, the ADuC706x provides the resolution required by today’s high-performance industrial and instrumentation equipment, while keeping the noise low. This performance, complemented by the simplicity of a single-chip solution, handles all data acquisition, processing and communications functions at the signal source.”
About the ADuC706x Family
Designed for 4–20 mA loop-powered applications in factory automation and for precision instruments, the ADuC706x family includes the ADuC7060, ADuC7061 and ADuC7062.
The devices feature an industry-best ADC noise performance of just 60 nV—20% better than the nearest competing part—and offer five times more processing power for a given clock rate. In addition to the 24-bit sigma-delta ADCs and ARM7 core with eight interrupt priority levels, the new precision analog microcontrollers incorporate 32 Kbytes of flash memory and 4 Kbytes of SRAM, a programmable gain amplifier, multiplexers, buffers, an auxiliary 24-bit ADC for cold junction compensation and interfacing to thermocouple applications, and SPI (serial peripheral interface), UART (universal asynchronous receivers-transmitters) and I²C ports. The devices consume just 2.6 mA with all peripherals activated.
The ADuC7060, available in a 7 mm × 7 mm 48-pin chip-scale (QFN) package, offers more analog-input channels and general-purpose I/Os than other devices in the family. The ADuC7061 and ADuC7062 come in 5 mm × 5 mm 32-pin chip-scale (QFN) packages, ideal for space-constrained applications. The ADuC7062 does not include the auxiliary ADC channel.
