Ultralow Noise, High Accuracy Voltage References

The AD7124-8 is a low power, low noise, completely integratedanalog front end for high precision measurement applications.The device contains a low noise, 24-bit ?-? analog-to-digitalconverter (ADC), and can be configured to have 8 differentialinputs or 15 single-ended or pseudo differential inputs. The onchiplow gain stage ensures that signals of small amplitude canbe interfaced directly to the ADC.One of the major advantages of the AD7124-8 is that it gives theuser the flexibility to employ one of three integrated powermodes. The current consumption, range of output data rates,and rms noise can be tailored with the power mode selected.The device also offers a multitude of filter options, ensuring thatthe user has the highest degree of flexibility.The AD7124-8 can achieve simultaneous 50 Hz and 60 Hzrejection when operating at an output data rate of 25 SPS (singlecycle settling), with rejection in excess of 80 dB achieved at loweroutput data rates.The AD7124-8 establishes the highest degree of signal chainintegration. The device contains a precision, low noise, lowdrift internal band gap reference and accepts an externaldifferential reference, which can be internally buffered. Otherkey integrated features include programmable low drift excitationcurrent sources, burnout currents, and a bias voltage generator,which sets the common-mode voltage of a channel to AVDD/2.The low-side power switch enables the user to power downbridge sensors between conversions, ensuring the absoluteminimal power consumption of the system. The device alsoallows the user the option of operating with either an internalclock or an external clock.The integrated channel sequencer allows several channels to beenabled simultaneously, and the AD7124-8 sequentially convertson each enabled channel, simplifying communication with thedevice. As many as 16 channels can be enabled at any time, achannel being defined as an analog input or a diagnostic suchas a power supply check or a reference check. This uniquefeature allows diagnostics to be interleaved with conversions.The AD7124-8 also supports per channel configuration. Thedevice allows eight configurations or setups. Each configurationconsists of gain, filter type, output data rate, buffering, andreference source. The user can assign any of these setups on achannel by channel basis.The AD7124-8 also has extensive diagnostic functionalityintegrated as part of its comprehensive feature set. Thesediagnostics include a cyclic redundancy check (CRC), signalchain checks, and serial interface checks, which lead to a morerobust solution. These diagnostics reduce the need for externalcomponents to implement diagnostics, resulting in reducedboard space needs, reduced design cycle times, and cost savings.The failure modes effects and diagnostic analysis (FMEDA) of atypical application has shown a safe failure fraction (SFF) greaterthan 90% according to IEC 61508.The device operates with a single analog power supply from 2.7 Vto 3.6 V or a dual 1.8 V power supply. The digital supply has arange of 1.65 V to 3.6 V. It is specified for a temperature rangeof ?40?C to +125?C. The AD7124-8 is housed in a 32-leadLFCSP package.Note that, throughout this data sheet, multifunction pins, suchas DOUT/RDY, are referred to either by the entire pin name orby a single function of the pin, for example, RDY, when onlythat function is relevant.Applications Temperature measurement Pressure measurement Industrial process control Instrumentation Smart transmitters

DARWIN is a new breed of low-power microcontrollers built to thrive in the rapidly evolving Internet of Things (IoT). They are smart, with the biggest memories in their class and a massively scalable memory architecture. They run forever, thanks to wearable-grade power technology. They are durable enough to withstand the most advanced cyberattacks. DARWIN microcontrollers are designed to run any application imaginable—in places where you would not dream of sending other microcontrollers.Generation UB microcontrollers are designed to handle the increasingly complex applications demanded by today's advanced battery-powered devices and wirelessly connected devices, while providing robust hardware security and Bluetooth® 5 Low Energy (BLE) radio connectivity.The MAX32665/MAX32666 UB class microcontrollers are advanced systems-on-chips featuring an Arm® Cortex®-M4 with FPU CPU for efficient computation of complex functions and algorithms with integrated power management.

Analog Comparators Ultra Fast ECL Single Comparator

The AD96685 and AD96687 are ultrafast voltage comparators. The AD96685 is a single comparator with a propagation delay of 2.5 ns, while the AD96687 is an equally fast dual comparator. Both devices exhibit a propagation delay dispersion of 50 ps, a crucial characteristic for high-speed comparators, indicating the difference in propagation delay under varying overdrive conditions.

Featuring a fast, high-precision differential input stage, these comparators maintain consistent propagation delay across a broad range of signals within the common-mode range from -2.5 V to +5 V. The outputs consist of complementary digital signals fully compatible with ECL 10 K and 10 KH logic families. These outputs provide ample drive current to directly interface with transmission lines terminated in 50 Ohms to -2 V. The inclusion of a level-sensitive latch input allows for tracking, track-hold, or sample-hold modes of operation.

Both the AD96685 and AD96687 are available in industrial temperature ranges (-25°C to +85°C) and military temperature ranges. Industrial range devices are offered in 16-pin DIP, SOIC, and 20-lead PLCC packages. Additionally, the AD96685 is available in a 10-pin TO-100 metal can.
