This is a PDF document about a 12-bit monitor and control system. The document introduces the AD7294 with multichannel ADC, DACs, temperature sensor, and current sense. The system features high accuracy, fast conversion time, and various input and output capabilities.

ADT7516/ADT7517/ADT7519 is a SPI/I2C compatible, temperature sensor, 4-channel ADC and quad voltage output DAC

The AD7575 is a high speed 8-bit ADC with a built-in track/hold function. The successive approximation conversion technique is used to achieve a fast conversion time of 5 µs, while the built-in track/hold allows full-scale signals up to 50 kHz (386 mV/µs slew rate) to be digitized. The AD7575 requires only a single +5 V supply and a low cost, 1.23 V bandgap reference in order to convert an input signal range of 0 to 2 VREF. The AD7575 is designed for easy interfacing to all popular 8-bit microprocessors using standard microprocessor control signals (CS and RD) to control starting of the conversion and reading of the data. The interface logic allows the AD7575 to be easily configured as a memory mapped device, and the part can be interfaced as SLOW-MEMORY or ROM. All data outputs of the AD7575 are latched and three-state buffered to allow direct connection to a microprocessor data.

AD8571/AD8572/AD8574 are AD company's zero-drift, single-supply, rail-to-rail input/output operational amplifiers. Its features are low bias current, low input drift, high gain, high CMRR, high PSRR, wide dynamic range, low supply current and fast recovery time. This series of amplifiers is suitable for temperature sensors, pressure sensors, precision current sensing, strain gauge amplifiers, medical instruments, thermocouple amplifiers and other applications.

The AD7655 is a low-cost, 4-channel, 16-bit, 1 MSPS PulSAR® ADC. It features 2 track-and-hold amplifiers, an analog input voltage range of 0V to 5V, and a parallel/serial 5V/3V interface, among other characteristics.

ADAU1966 is a 16-channel high performance differential output, 192 kHz, 24-bit DAC

AD1955 is a high-performance multibit ½-DAC with SACD playback.

AD1953 is a 5V 3-channel audio DAC system that supports 2-channel or 6-channel packed mode, with a sampling rate of up to 48kHz. The product has 7 Biquad filter sections, dual dynamic processors, 0ms to 6ms variable delay/channel, stereo spreading algorithm and program RAM.

The AD9540 is a 655MHz low jitter clock generator from ADI company. It has excellent intrinsic jitter performance, 25Mb/s write-speed serial I/O control, 200MHz phase frequency detector inputs, 655MHz programmable input dividers, programmable RF divider, 8 programmable internal clock rates, 93 fS resolution programmable edge delay, 1.8V power supply, 3.3V power supply, programmable charge pump current, multi-chip synchronization, dual-mode PLL lock detect and 655MHz CML mode PECL compliant driver.

The AD1934 is a high-performance single-chip that provides eight digital-to-analog converters (DACs) with single-ended outputs that can be controlled via SPI and support 24 bits and 8 kHz to 192 kHz sample rates.

AD1933 is a high performance, single chip that provides eight digital-to-analog converters (DACs) that support 8 kHz to 192 kHz sample rates, with a 110 dB dynamic range and SNR -96 dB THD + N, 3.3 V single supply, and software controllable switching and mute functions.

The AD1866 is a complete dual 16-bit DAC offering excellent performance while requiring a single +5 V power supply. It is fabricated on Analog Devices’ ABCMOS wafer fabrication process. The monolithic chip includes CMOS logic elements, bipolar and MOS linear elements and laser trimmed, thin- film resistor elements. Careful design and layout techniques have resulted in low distortion, low noise, high channel separation and low power

The AD1859 is a complete 16-/18-bit single-chip stereo digital audio playback subsystem. It comprises a variable rate digital interpolation filter, a revolutionary multibit sigma-delta (∑∆) modulator with dither, a jitter-tolerant DAC, switched capacitor and continuous time analog filters, and analog output drive circuitry. Other features include an on-chip stereo attenuator and mute, programmed through an SPI-compatible serial control port. The key differentiating feature of the AD1859 is its asynchronous master clock capability. Previous ∑∆ audio DACs required a high frequency master clock at 256 or 384 times the intended audio sample rate. The generation and management of this high frequency synchronous clock is burdensome to the board level designer. The analog performance of conventional single bit ∑∆ DACs is also dependent on the spectral purity of the sample and master clocks. The AD1859 has a digital Phase Locked Loop (PLL) which allows the master clock to be asynchronous, and which also strongly rejects jitter on the sample clock (left/right clock). The digital PLL allows the AD1859 to be clocked with a single frequency (27 MHz for example) while the sample frequency (as determined from the left/right clock) can vary over a wide range. The digital PLL will lock to the new sample rate in approximately 100 ms. Jitter components 15 Hz above and below the sample frequency are rejected by 6 d

AD1852 is a high-performance audio DAC launched by Analog Devices. It supports 24-bit, 192kHz sampling rate, supports 16-bit/18-bit/20-bit/24-bit data, has perfect differential linearity restoration function, can reduce idle tones and noise floor noise, minimize jitter, and has 117dB signal-to-noise ratio (not muted), 114dB dynamic range (not muted), -105dB THD+N (mono application circuit), -102dB THD+N (stereo application circuit) and other features.
