Analogue / Linear / Mixed Signal ICs

Ampleon has introduced tough 1.4 and 1.6kW LDMOS RF amplifiers, designed to handle 65:1 VSWR. The ART1K6x series each include a pair (p-channel + n-channel) of mosfets. They operate from 1MHz to 450MHz in 48V Class E and 55V Class AB applications. “The maximum Vds figure supported being 177V. They can cope with a 65:1 VSWR,  which means that any potential ...

Diodes has introduced ICs that extend the physical range of PCIe 3.0 and SATA3 connections, while meeting Microsoft’s ‘modern stand-by mode’ requirements. Operating from a 3.3V rail, in stand-by mode, the 1-lane (or 2 channel) PI3EQX12902E consumes 1.7mW, which rises to 3.3mW for the 2-lane (4 channel) PI3EQX12904E. A pin selects PCIe 3.0 or SATA3 mode, and data rates up to ...

Richardson RFPD is offering availability and full design support for two high-speed converters from Analog Devices. The AD9081 and AD9082 mixed-signal front-ends combine high-performance analog and digital signal processing and allow designers to install multiband radios in the same footprint as single-band radios. By shifting more of the frequency translation and filtering from the analog to the digital domain, the ...

For electricity metering, ADE9322B is a two-channel Σ-Δ ADC from Analog Devices. It current channel is designed to interface with a shunt resistor and its voltage channel interfaces with potential divider, both connected to the power rails, SPI and UART ports allow access to its internal registers. ‘mSure’ branding abounds. “mSure converts two analogue input signals into a single bit ...

Amazing Microelectronic of Taiwan has introduced a low-capacitance ESD protection array for data and audio interfaces. “The multifaceted AZ1015-02N maintains low surge clamping voltage for ESD/EOS  protection and low capacitance to keep signal integrity,” according to New Yorker Electronics, which is stocking the part. “The device is used for audio interface, monitor and flat panel display, USB2.0 and SIM ports.” ...

U-blox is creating automotive-grade positioning modules that combine data from GNSS (satellite) and internal inertial sources. “The modules are all automotive grade, with the NEO-M9L-01A variant offering an operational temperature range up to 105°C, making it suitable for integration on the roof, behind the windscreen, or inside electronics control units,” according to the company. Inside is a six-axis inertial measurement ...

Aiming at functional safety requirements, Maxim has added self-test to a voltage monitor and reset IC for driver assistance systems. Called MAX16137, it has two forms of BIST (built-in self-test): one that checks the chip at power-up and a second that checks on-demand. Just like any reset chip, it holds its reset output low as power-up progresses, then releases it high ...

TI is claiming “Industry’s fastest 18bit ADC for its 65Msample/s ADC3683. The dual channel device has a 900MHz bandwidth and will accept signal sup to 3.2Vp-p. Signal to noise ratio is 84.2dB* and noise spectral density -160dBfs/Hz Effective number of bits (ENOB) and spurious-free dynamic range (SFDR) are 13.7 and 89dB respectively. All for a typical power consumption of 186mW for both ...

Maxim has introduced 3A controller for supercapacitors used to back-up battery-powered low-voltage power rails. Called MAX38889, it is rated for operation between 2.5V and 5.5V on the supplied rail and 500mV to 5.5V on the capacitor. The converter bucks down from a powered voltage rail to the supercapacitor and, when the power source is removed, automatically reverses direction and boosts ...

Analog Devices has introduced a 16bit, 15Msample/s data acquisition module for digitising fast transient signals in power analysis applications “enabling low latency digital control in hardware-in-the-loop or source measurement unit applications”, according to the company. Called ADAQ23875, it has differential input signal conditioning circuitry including 0.005% matched resistors to implement a ±2.048V input range with a 4.096V reference – the reference is also ...
