Mixed Signal/Analog

Catalyst Semiconductor has expanded its line of bus products with the CAT9534, an 8-bit general purpose input/output (GPIO) expander for I2C and SMBus-based systems. The CAT9534 is pin-for-pin and functionally compatible with Catalyst’s industry-standard CAT9554, but operates at 100 times lower standby power, making it the perfect choice for battery-powered and “green” systems applications.

Linear Technology has introduced the LTC2217, a low noise, high performance 16-bit, 105Msps Analog to Digital Converter (ADC) with 81.2dBFS Signal-to-Noise Ratio (SNR) and 100dBc Spurious Free Dynamic Range (SFDR). Ultra-low jitter helps maintain the high SNR at high input frequencies, yielding 80.4dBFS SNR at 70MHz, while the high linearity sample/hold circuitry allows for low distortion of 92dBFS at 70MHz. The single 3.3V power supply requires ...

Texas Instruments has announced two multi-channel, 16-bit, delta-sigma analog-to-digital converters (ADCs), which combine outstanding DC accuracy and AC performance with cost-effective integration. The ADS1174 (4-channel) and ADS1178 (8-channel) provide a simultaneous-sampling measurement system for demanding signal acquisition applications, such as power metering, defibrillators and ECG monitors, as well as pressure sensors, coriolis flow meters...

Linear Technology has introduced the LTC2309, a 12-bit analog-to-digital converter (ADC) that communicates via an I2C-compatible 2-wire interface with 14ksps throughput rate. This flexible ADC features an 8-channel integrated multiplexer to measure eight single-ended input channels, four differential channels, or combinations of both.

Linear Technology has introduced the LTC2932, a six-channel supply monitor that includes separate open-drain voltage comparator outputs for individual supply monitoring. The LTC2932 is designed for monitoring network servers, telecom and industrial equipment with numerous supply voltage rails.

Texas Instruments has introduced a family of 16-bit, single channel, 40- and 80-MSPS analog-to-digital converters (ADCs) which provide the highest signal-to-noise ratio (SNR) with very low power consumption. The devices’ low noise floor improves accuracy in test and measurement, receiver sensitivity in wireless communications, and image quality in medical, industrial and military applications.

Analog Devices has introduced two analog output drivers that are said to significantly improve the efficiency and reliability of process control applications, including those operating with high compliance voltages and temperatures. Using technological advancements enabled by ADI’s iCMOS industrial process technology, the AD5750 and AD5751 output drivers achieve a three-fold improvement in accuracy over competing solutions, providing an accurac...

Vishay Intertechnology has released eight new high-frequency, low-charge-injection analog multiplexers and switches for precision instrumentation applications. They are also the first devices of their kind to be offered in the leadless 1.8-mm by 2.6-mm miniQFN package, in addition to the standard TSSOP and SOIC packages.

Linear Technology has introduced the LTM9001, the first in a series of System in a Package (SiP) signal chain receiver modules, leveraging Linear’s breakthrough uModule packaging technology. This new family of integrated receiver subsystems is intended to bridge the expertise gap between the RF world and digital domain to provide ease of use and shortened time to market.

The new A1351 from Allegro MicroSystems Europe is a high-precision linear Hall-effect sensor IC with a 125 Hz push/pull pulse-width-modulated (PWM) output that is proportional to an applied magnetic field. The A1351 converts an analogue signal from its internal Hall sensor element to a digitally encoded PWM output signal. The coupled noise immunity of the digitally encoded PWM output is far superior to the noise immunity of an analogue output sig...
