Analogue / Linear / Mixed Signal ICs

ADL5580 is a SiGe dc to 10.0GHz differential-in differential-out gain block from Analog Devices, which has a digital bus for signal path tweaking. “The amplifier offers a referred-to-input noise spectral density of 2.24nV/√Hz at 1GHz and is optimised for distortion performance over a wide frequency range, making the device ideal for driving high speed 12bit to 16bit ADCs,” according to ...

Analog Devices has created an alternative to its venerable LTZ1000 ultra-precision voltage reference, with better initial accuracy and less noise, although not every parameter is improved. Called ADR1000 (right), the nominally 6.62V part is a pin-compatible replacement for the LTZ1000 (below), and like it includes a buried Zener reference, a heater for temperature stabilization and a temperature sensor. As with ...

E-Peas has unveiled boost and buck energy harvesting controllers that can start up on a few hundred millivolts and provide regulated outputs as well as energy storage mediation. There are three parts: AEM00940: harvesting and storage manager with LDO Two regulated outputs Supercapacitor or battery storage Optional primary battery back-up source Boost harvester interface Harvest voltage settable across 50mV to 4.5V 380mV ...

TI has introduced a voltage reference that typically runs from 680nA and yet has a max initial error of ±0.05% and a max temperature coefficient of 10ppm/°C across -40 to 125°C – and it will operate down to -55°C. Called REF35, it will run from up to 6V and different versions offer outputs of 1.024, 1.2, 1.25, 1.6, 1.8, 2.048, 2.5, 3, 3.3, ...

Menlo Micro has released another MEMS electro-mechanical relay, this time a single-pole four-throw (SP4T) dc-18GHz switch. MM5120 will handle 25W (150W pulsed), according to the company, though its 5.2 x 4.2mm LGA package. Insertion loss is typically <0.6dB at 12GHz. IP3 linearity is said to be >95dBm. Contact movement is though electrostatic attraction, with the necessary voltage generated by an integrated charge ...

ADI’s MAX30009 BioZ AFE  claims to reduce the size and extends the life of bioimpedance (BioZ) remote-patient monitoring (RPM) devices. For developers of small, battery-powered, continuously wearable devices, this AFE on a chip offers clinical-grade vital sign measurements of bioimpedance analysis for patient health assessment for wellness wearables and medical-grade patches. The device  monitors a  range of BioZ modalities through ...

Panasonic is to squeezed a single-pole normally-closed mosfet relay into a 1.95 x 1.8 x 0.8mm TSON package. An extension of the company’s CC series, “we are pretty certain that our 1FormB TSON type is currently matchless throughout the industry as far as size and current consumption are concerned”, said Panasonic’s Michael Renner. “With just an eighth of a SOP4 package’s ...

Maxim has quietly released a couple of op-amp families, one very low power and the other blending high speed, precision and low noise. MAX40023 and MAX40024 are single and dual amplifiers that will run from 1.6 to 3.6V, typically for 17μA per channel. A shut-down pin typically takes this to 55nA. Both inputs and outputs swing rail-to-rail and, commensurate with such ...

Diodes has announced an ideal diode controller for reverse discharge protection. Called DZDH0401DW, it is designed to work with a p-channel mosfet in the high-side rail in systems up to 40V. It might better be described as a ‘nearly ideal diode controller’ as it draws some current from the output circuit when no input is connected – 147μA if a ...

Infineon has created a 7 x 7mm multi-chip module that can deliver two audio channels of up to 100W each. Called MA5332MS, the company claims 95% power efficiency for the Class-D amplifier when driving that power into 4Ω loads (10% THD+N, ±36.5V supply). Looking at the data sheet, up to 90W is available with <0.1% THD+N. Providing the load is 1W, THD+N ...
