Analog Devices, Inc. defines innovation and excellence in signal processing.
ADI's analog, mixed-signal, and digital signal processing (DSP) integrated circuits (IC) play a fundamental role in converting, conditioning, and processing real-world phenomena such as light, sound, temperature, motion, and pressure into electrical signals to be used in a wide array of electronic equipment.
16-bit, 1-Msamples/s ADAS3022 is suited for power-line monitors, process and motor control, patient monitoring other industrial and instrumentation systems that operate within the ±10-V industrial range.
AD9525 RF clock IC - Lowest jitter for communications and instrumentation equipment, requiring high-speed data conversion and optimum SNR performance.
The AD9525 operates over the extended industrial temperature range of -40°C to +85°C, is available in a 48-lead LFCSP and can be operated from a single 3.3 V supply. The external VCXO or VCO can have an operating voltage of up to 5.5 V.
The high performance ADXL350 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) and selectable measurement ranges up to ±8 g.
ADXL350 offers industry-leading temp° performance with guaranteed min/max specs for offset over temp°. Digital output data formatted as 16-bit twos complement and accessible through either SPI (3- or 4-wire) or I2C digital interface.
The AD8237 micro-power, zero-drift precision instrumentation amplifier is claimed to offer a power-efficient solution for precision signal and sensor conditioning, it features a low input offset drift of less than 0.3 µV/°C and an input signal range that extends 300 mV beyond the supply rails.
The AD8237 operates off a single supply voltage of 1.8 V to 5.5 V and is in a compact MSOP-8 package. The gain (1 to 1000) is set by the ratio of two external resistors, which combined with industry leading gain error performance, provides superior gain accuracy over temperature.
The AD9645 is a two-channel, high-performance 14-bit, 125-MSPS A/D converter reducing total power consumption by 22% over competing solutions. Delivering high speed and wide dynamic range at lower power, the A/D converter is available in a 5-mm x 5-mm package, a 30 percent space savings over competitive solutions.
The ADM3252E is a high speed, 2.5 kV fully isolated, dual-channel RS-232/V.28 transceiver device that is operational from a single 3.3 V or 5 V power supply.
Because of high ESD protection on the RIN1, RIN2, TOUT1, and TOUT2 pins, the ADM3252E is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently plugged and unplugged.
The ADM3252E provides four independent isolation channels using the integrated and isolated power of isoPower™. There is no requirement to use a separate isolated dc-to-dc converter. Chip scale transformer iCoupler® technology from Analog Devices, Inc., is used for both the isolation of the logic signals and the integrated dc-to-dc converter. The result is a total isolation solution.
The ADE7816 is a highly accurate, multichannel metering device that is capable of measuring one voltage channel and up to six current channels. It measures line voltage and current and calculates active and reactive energy, as well as instantaneous rms voltage and current.
The device incorporates seven sigma-delta (Σ-Δ) ADCs with a high accuracy energy measurement core. The six current input channels allow multiple loads to be measured simultaneously.
The voltage channel and the six current channels each have a complete signal path allowing for a full range of measurements. Each input channel supports a flexible gain stage and is suitable for use with current transformers (CTs).
Six on-chip digital integrators facilitate the use of the Rogowski coil sensors.
The ADE7816 provides access to on-chip meter registers via either the SPI or I2C interface. A dedicated high speed interface, the high speed data capture (HSDC) port, can be used in conjunction with I2C to provide access to real-time ADC output information.
A full range of power quality information, such as overcurrent, overvoltage, peak, and sag detection, is accessible via the two external interrupt pins, IRQ0 and IRQ1.
The ADE7816 energy metering IC operates from a 3.3 V supply volt
The ADP2370/ADP2371 are high efficiency, low quiescent current, 800 mA buck (step-down) dc-to-dc converters in small 8-lead, 3 mm x 3 mm LFCSP (QFN) packages. The total solution requires only three tiny external components.
The buck regulator uses a proprietary high speed current mode, constant frequency PWM control scheme for excellent stability and transient response. The need for an external rectifier is eliminated by using a high efficiency synchronous rectifier architecture.
To ensure the longest battery life in portable applications, the ADP2370/ADP2371 employ a power saving variable frequency mode that reduces the switching frequency under light load conditions. The ADP2370/ADP2371 operate from input voltages of 3.2 V to 15 V allowing the use of multiple alkaline/NiMH, lithium cells, or other standard power sources.
The ADuCM360 is a fully integrated, 4 kSPS, 24-bit data acquisition system incorporating dual, high performance multi-channel sigma-delta analog-to-digital converters (ADCs), 32-bit ARM Cortex M3® MCU, and Flash/EE memory on a single chip.
The part is designed for direct interfacing to external precision sensors in both wired and battery powered applications.
The device contains an on-chip 32 KHz oscillator and an internal 16MHz high-frequency oscillator. This clock is routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The maximum core clock speed is 16MHz and this is not limited by operating voltage or temperature.
The microcontroller core is a low power Cortex-M3 core from ARM. It is a 32-bit RISC machine, offering up to 20 MIPS peak performance.
The Cortex-M3 MCU incorporates a flexible 11-channel DMA controller supporting all wired (SPI, UART, I2C) communication peripherals. 128k Bytes of non-volatile Flash/EE and 8k Bytes of SRAM are also integrated on-chip.
