Analogue / Linear / Mixed Signal ICs

Linear Technology’s LTC2000A is a 16-bit, 2.7Gsample/s digital-to-analogue converter (DAC) with a spectral purity for broadband wired-and-wireless communications and radar applications. The chip’s spectral purity is 80dBc SFDR at 50MHz output and 72dBc SFDR at 1080MHz output. The device features better than 78dBc 2-tone intermodulation distortion (IMD) from DC to 1080MHz output, low phase noise and a wide 2.1GHz -3dB ...

Ricoh has introduced a battery protection IC for rechargeable one-cell lithium-ion and lithium polymer batteries which incorporates a two-step excess discharge current detector, used with an external current sense resistor. The R5486 monitors the charge and discharge process continuously and intervenes when the process is at risk of going beyond the safe operation range of the battery cell. Discharge protection ...

Called SiT8021, power consumption is 110µA for 3MHz, and the device is available in chip-scale packages (CSPs) as small as 1.5×0.8mm. The MEMS part is a 524kHz double tuning fork resonator (see diagram), identical to the one in a similar 32kHz oscillator released three months ago. Made on a silicon-on-insulator wafer and hermetically sealed with a high-temperature-grown (1,100°C) epi polysilicon ...

Texas Instruments has introduced a hardware and software kit for industrial drive and servo design with support for real-time Ethernet communications and functional safety topologies. Based on the real-time control architecture of TI’s C2000 microcontrollers, DesignDRIVE  design kit can be used for the development of industrial inverter and servo drives used in robotics and computer numerical control machinery. The kit includes ...

The ACS722 and ACS723 Hall-effect current sensor ICs from Allegro MicroSystems Europe are being offered in a new high-isolation SOIC16 package. It is a low-profile surface-mount package which provides a 4,800V RMS isolation rating, which is the highest available from the supplier’s family of surface-mount current sensor ICs. PCIM: Your Electronics Weekly guide » Each device consists of a low-offset, ...

Semtech has a three-pin transient voltage suppression (TVS) array device designed for protecting high-speed differential pairs common in interfaces such as USB 3.0, MHL and HDMI 1.4. The RClamp0552T is housed in a 1.0 x 0.6mm package with a nominal height of only 0.4mm. Its three leads are spaced at a pitch of 0.34mm, and the flow-through design of the ...

Crystek has a VCO which operates at 3500 MHz with a control voltage range of 0.3 V~4.9 V.

Micrel has a family of pin-compatible high voltage synchronous step-down switching regulators with integrated power switches capable of providing up to 4A (MIC28513) output current and a wide input supply range from 4.6V to 70V (MIC28512). The devices are available with both Hyper Speed Control and HyperLight Load architectures, which allow for high VIN (low VOUT) operation and ultra-fast transient ...

Toshiba Electronics has introduced a brushed motor pre-driver IC that meets the requirements set in Automotive Safety Integrity Level D (ASIL-D). Designed for use in safety-critical automotive systems the device combines a pre-driver circuit, dual motor current detection circuit that converts motor current to voltage and output to the microcontroller. There is also on-chip motor direction detection circuitry that detects whether ...

Linear Technology has introduced a comparator with fast rise and fall times of 1.2ns and a toggle frequency of 280MHz. Designed for driving logic levels from 3.3V down to 1.8V, the LTC6752 has a specified 2.9ns propagation delay and overdrive dispersion of 1.8ns. Jitter is 4.5ps for a 100mVpp, 100MHz sinusoidal input, and the outputs swing to within 200mV of ...
