SAR 16-bit ADC digitizes up to up to 750 kHz
Linear Technology Corporation introduces the LTC2320-16, a 16-bit 1.5Msps per channel, no latency successive approximation register (SAR) ADC with eight simultaneously sampling channels supporting a rail-to-rail input common mode range. The LTC2320-16 features a flexible analog front end that accepts fully differential, unipolar or bipolar analog input signals, as well as arbitrary input signals, and […]
Isolated RS-485 µModule transceiver meets medical IEC 60601-1 requirements
Linear Technology Corporation introduces the LTM2885, an isolated RS485 µModule® transceiver for guarding against large ground-to-ground differentials. Many industrial, utility, medical, military, and intrinsic safety applications require isolation components with increased voltage and spatial separation for human safety. The LTM2885 provides 6500VRMS reinforced isolation between the logic level interface and the transceiver bus pins, far […]
32-Bit SAR ADC with digitally filtered, 1-Msps no-latency outputs
Linear Technology Corporation introduces the LTC2508-32, an ultrahigh precision 32-bit successive approximation register (SAR) analog-to-digital converter (ADC). Many high performance applications, including data acquisition, industrial control and medical instrumentation, require both accuracy and speed. This is often achieved by using a high resolution delta-sigma ADC and a high speed SAR ADC in the same system. […]
5-dB Gain Block Delivers 47 dBm OIP3 Linearity with Low Noise
Linear Technology announces the LTC6433-15, a wideband 15dB gain block amplifier offering outstanding linearity of 47dBm OIP3 (output third order intercept) and 3.22dB noise figure at 150MHz. The amplifier has excellent OP1dB (output 1dB compression point) of 19.2dBm. The LTC6433-15 is uniquely different from other gain block amplifiers that are typically built using GaAs or pHEMT […]
Harvesting power for IoT devices
by Tony Armstrong, Linear Technology Sometimes energy for IoT devices comes from the likes of thermoelectric generators and thermopiles thanks to power management ICs that double as energy misers. Power consumption is a controversial topic when it comes to IoT devices. At the low end of the power spectrum are devices where most of the […]
2 GHz-to-14 GHz mixer with LO frequency doubler gives dc to 6-GHz IF bandwidth
Linear Technology announces the LTC5548, a double balanced mixer that operates either as an up- or downconverter with an exceptionally wide frequency range from 2GHz to 14GHz. The LTC5548 features integrated balun transformers at the RF and LO ports, providing 50Ω match from 2GHz to 13.6GHz and from 1GHz to 12GHz at each port, respectively, […]
18-Bit, 8-Channel Multiplexed SAR ADC with Independently Configurable Input Ranges
Linear Technology Corporation introduces the LTC2335-18, an 18-bit, 8-channel 1Msps multiplexed input successive approximation register (SAR) ADC with independently configurable input ranges. Each SoftSpan™ input can be software configured on a conversion-by-conversion basis to accept ±10.24V, 0V to 10.24V, ±5.12V or 0V to 5.12V true bipolar input signals. The on-chip sequencer allows the LTC2335-18 to […]
Unity-gain difference amp precisely level shifts and buffers small difference signals, rejects up to ±270 V common mode
Linear Technology introduces the LT6375, a unity-gain difference amplifier with integrated precision matched resistors, which precisely level shifts and buffers small difference signals while rejecting up to ±270V common mode. The A-grade version achieves unprecedented performance: CMRR is 97dB (min), initial gain error is 35ppm (max), gain drift is 1ppm/°C (max) and gain nonlinearity is […]
Variable gain amplifiers
It is not uncommon to need an adjustable gain in an analog signal processing chain. If the adjustment is manual then it is pretty straightforward — you can use a potentiometer. When you need the adjustment under digital control then it becomes more complicated. If you need a digitally adjustable instrumentation amplifier then there are […]
