Linear introduces small boost DC/DC converter with avalanche photodiode current monitor

The LT3905 from Linear Technology is a fixed frequency, current-mode step-up DC/DC converter designed to bias avalanche photodiodes (APD) in optical receivers. The LT3905 features high side APD current monitoring with over five decades of dynamic range and better than 2% relative accuracy over the 3µA to 3mA range. The maximum APD current is programmed with a single resistor and a fast current limiter with indicator protects the APD during overload conditions.

ADI introduces industry's fastest 18-bit SAR A/D converter

Analog Devices Inc. introduced an 18-bit PulSAR® A/D converter with 5-MSPS throughput that is twice the speed of any available SAR (successive-approximation register) converter. With its industry leading throughput, best-in-class noise floor and high linearity, the AD7960 PulSAR A/D converter was designed for low-power signal chains, multiplexed systems such as digital X-ray, and oversampling applications including spectroscopy, MRI gradient control and gas chromatography.

TI introduces industry's fastest 4-channel, 14-bit ADC at 250 MSPS

Texas Instruments Inc. (TI) introduced the industry’s fastest 4-channel, 14-bit analog-to-digital converter (ADC), clocking in at 250 MSPS. The high-density ADS4449 enables receiver systems to support up to 125 MHz of instantaneous bandwidth in extremely small forms, such as multiple input and multiple output (MIMO) base stations and munitions guidance, or in greater density applications, such as active electrically scanned array (AESA) and other phased-array radars.

Linear introduces 100mA synchronous buck converter

Linear Technology announces the LTC3639, a 150V input-capable synchronous buck converter that delivers up to 100mA of continuous output current. It operates from an input voltage range of 4.5V to 150V, eliminating the need for an external transient suspension device. The LTC3639 utilizes internal synchronous rectification and a programmable peak current-mode design to optimize efficiency over a broad range of output currents.

ADI’s 24-bit sigma-delta A/D converter achieves twice the speed of competing converters

Analog Devices Inc. (ADI) introduced a multiplexed 24-bit sigma-delta A/D converter that doubles the throughput rate of alternative sigma-delta converters while dissipating less power. Designed for process automation and instrumentation systems where data channel density is increasing and channels must be monitored faster, ADI’s new AD7176-2 A/D converter achieves a 50 kSPS (thousand samples per second) multi-channel scan rate.
