Analogue / Linear / Mixed Signal ICs

iC-Haus will demonstrate its latest 26bit resolution optical encoder IC at SPS next month in Nuremberg. iC-RT2624, as it will be known, is aimed at both housed and kit encoders, and will achieve its 26bit resolution using interpolation with standard 26mm code discs, the company claims “even in demanding, dynamic applications”. AB quadrature and Z outputs are available as is, ...

STMicroelectronics is aiming at industrial and telecom power supplies with a 220V half-bridge driver for GaN power transistors. With a maximum rail voltage of 220V, STDRIVEG211, as it will be known, is intended to work from 72V batteries and 110Vac power lines. To protect the GaN gates, the two drive voltages are regulated to 6V maximum, and under-voltage lock-out it ...

Microchip has created a four-channel thermocouple measurement IC with ±1.5°C accuracy. “MCP9604 delivers accuracy at four thermocouple locations by using higher-order NIST ITS-90 equations rather than the single-order linear approximations of analog amplifier designs,” according to the company. “As an example, it achieves ninth-order accuracy with K-type thermocouples, all in one integrated chip containing the ADCs, cold junction compensation temperature ...

Melexis has added a thermistor input to two of its combined current and voltage sensors. MLX91230KDC-BBC-200-RE is a ±512mT Hall-based sensor and comes in an SOIC8 MLX91231KGO-BBC-000-RE is a -100mV to +256mV shunt sensor and comes in a TSSOP16 “The integration of the NTC input into the MLX91230 and MLX91231 sensors improves the detection of variations in system temperatures. For ...

Vishay has introduced a precision isolation amplifier with 5kVrms isolation test voltage and 150kV/μs typical (100kV/μs min) common-mode transient immunity: VIA0050DD. “Isolation amplifiers in the VIA series have been developed for applications that require thermal stability and measurement accuracy,” according to distributor Rutronik, which is stocking the parts, and laims: “They guarantee reliable and robust performance even in harsh environments, ...

Rohm has introduced a tiny nano-power rail-to-rail op-amp for sensor amplification, in a 910 x 800μm WLCSP (wafer-level chip-scale package). TLR1901GXZ, as it will be known, is CMOS and has a maximum input offset voltage of 550μV (3Vdd 25°C), drifting at 7μV/°C. Operation is across 1.7 to 5.5V and -40 to +85°C, and typical supply current is 160nA (at 3Vdd, ...

Melexis has squeezed a magnetic circuit inside an SMD package to get an end-sensitive Hall effect latch for slimline motor applications. “We’ve responded to the automotive industry’s demand for more compact motor latch sensors,” it said. “Lateral sensing in a surface-mount TSOT-3L package eliminates the need for through-hole components.” They are part of the existing MLX92211 family, the rest of ...

Rutronik is stocking an evaluation board for a power management IC (PMIC) for wearables. The IC, Nordic Semiconductor’s nPM1304, has a 4 – 100mA linear battery charger with programmable termination voltage, and four power outputs via two 200mA dc-dc converters and two 50mA LDOs – the LDOs can also be set-up as 100mA load switches. “nPM1304 is configurable via an ...

Osram has created an optical time-of-flight sensor with a 48 x 32 pixel receiving array that builds up a 1,536 point depth map as wide as 80° and at ranges from 10mm to 11m. “It is designed to detect subtle spatial differences and distinguish closely spaced or slightly varied objects. [It] can tell whether an espresso cup or a travel ...

Diodes has announced four automotive buck converters for 48V rail point-of-load use. The parts are similar, but rated at 5 to 100V or 5 to 80Vin, and 2.5A or 3.5A out. There are not synchronous rectifier ICs. Instead they include a 500mΩ (950mΩ max) series switch and expect a high current Schottky diode to be connected externally. Part numbers are ...
