Texas Instruments is aiming at robot motor control up to 60V with a series of isolated ADCs that include 200V barriers and come in 8pad 3.5 x 2.7mm VSON packaging. Each has a ΣΔ ADC on the hot side, an isolation barrier, then a digital interface on the cool side. The output is a modulated bit stream synchronised to an ...
Nisshinbo Micro Devices has released a series of industrial 5V analogue front end ICs with high-resolution ΣΔ converters, input multiplexers, programmable gain amplifiers and sensor excitation current sources. NA2202 has 16bit resolution NA2203 has 20bit resolution NA2204 has 24bit resolution “Microcontrollers with 5V operating voltage are still widely used in the industrial equipment market, according to the company. “In order ...
At the IEEE VLSI Symposium this week, Imec revealed two ADCs for 5GHz ‘beyond 5G’ communication, one for base stations and one for phones. The base station ADC operates over bands up to 5GHz. It is a 10Gsample/s cmos hierarchical time-interleaved ADC that delivers 9 ENOB (effective number of bits) at low frequencies and 8.2 ENOB at Nyquist. SFDR (spurious-free ...
Infineon has introduced microcontrollers for monitoring vehicle Pb-acid batteries, that can be powered directly from the battery and include a pair of high-accuracy ADCs. Operation is over 3.6 to 28V, with reduced function up to 42V, and the drvices have been developed with functional safety in mind. “The device is developed compliant to ISO 26262, meeting all process requirements for ...
Renesas has added a 24bit ΣΔ (sigma-delta) ADC to a 48 MHz Arm Cortex-M23 microprocessor, as well as dual-bank code flash for over-the-air firmware updates. “RA2A2 devices offer multiple power structures and voltage detection hardware to realise energy-efficient operation as low as 100µA/MHz in active mode, and 0.40µA in software stand-by mode,” according to the company. “An independent power supply ...
Abaco Systems latest analogue front-end mezzanine card for FPGAs has been tailored for software defined radio, as well as electronic warfare, radar, test and measurement. FMC300, as it will be known, has 7GHz of usable analogue bandwidth, claims the company, with multiple channels offering up to 12bit 6Gsample/s ADC and up to 16bit 12Gsample/s DAC through a JESD204B/C interface. Data ...
International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise figures from Class-D amplifiers, plus a sophisticated Class-H scheme to improve headphone amplifier efficiency. Starting with that headphone amplifier: Class-H is a way to decrease the dissipation of an analogue output stage ...
Renesas has revamped the high-accuracy analogue front-end in its 32bit RX microcontrollers. Implemented in RX23E-B MCUs, the 24bit ΔΣ ADC, depending on configuration, can now convert at up to 125ksample/s – eight times faster than existing RX23E-A MCUs – or achieve a third of the noise – to 0.18µVrms at 1ksample/s. 24bit effective resolution can be achieved at 3.8sample/s. To go ...
Designed for work in circuits with varied voltage levels. Until recently, a very common problem faced by electronic circuit designers was the difference in supply voltage standards between microcontrollers (e.g. 3.3 V) and peripheral ICs (e.g. 5 V). In order for them to operate together, the use of additional voltage translators was required, which made the device more complicated and ...
