The AD7723 is a complete 16-bit sigma-delta ADC. The part operates from a 5 V supply. The analog input is continuously sampled, eliminating the need for an external sample-and-hold. The modulator output is processed by a finite impulse response (FIR) digital filter. The on-chip filtering combined with a high oversampling ratio reduces the external antialias requirements to first order in most cases. The digital filter frequency response can be programmed to be either low-pass or band-pass. The AD7723 provides 16-bit performance

The AD7856 is a high speed, low power, 14-bit ADC that operates from a single 5 V power supply. It has automatic calibration, flexible power management, multiple input ranges, multiple input channels, self- and system calibration, and a versatile serial I/O port.

The AD7863 is a high speed, low power, dual 14-bit analog-to-digital converter that operates from a single 5 V supply. It features two fast 14-bit ADCs, four input channels, simultaneous sampling and conversion, 5.2 μs conversion time, and single supply operation.

The AD9051 is a complete 10-bit monolithic sampling analog-to-digital converter (ADC) with an onboard track-and-hold and reference. The unit is designed for low cost, high performance applications and requires only 5 V and an encode clock to achieve 60 MSPS sample rates with 10-bit resolution. The encode clock is TTL compatible and the digital outputs are CMOS; both can operate with 5 V/3 V logic. The two-step architecture enables higher sampling rates and lower power consumption.

AD9225 is a monolithic single-supply 12-bit 25 MSPS analog-to-digital converter with an on-chip, high performance sample-and-hold amplifier and voltage reference, features low power dissipation, no missing codes, guaranteed differential nonlinearity error, complete on-chip sample-and-hold amplifier and voltage reference, signal-to-noise and distortion ratio 71 dB, spurious-free dynamic range -85 dB, out-of-range indicator, straight binary output data, 28-lead SOIC and 28-lead SSOP compatible with 3 V logic.

The AD6640 is a high performance, low power, 12-bit analog-to-digital converter that runs on a single 5 V supply and supports 65 MSPS sample rate. It is designed for use in multichannel, multimode receivers, cellular/PCS base stations, and other applications.

The AD7339 is a composite IC that contains both DAC and ADC functions. The device includes an 8-bit parallel A-to-D converter. Two 8-bit parallel DACs are also included as are two serial control DACs. The AD7339, which operates with a single 5 V power supply, has a bandgap reference on board with a power-down mode.

The AD7827 is a high speed, single channel, low power, analog-to-digital converter with a maximum throughput of 1 MSPS that operates from a single 3 V or 5 V supply.

The AD9201 is a dual channel, 20 MSPS, 10-bit CMOS ADC from Analog Devices. The AD9201 is optimized specifically for applications where close matching between two ADCs is required (e.g., I/Q channels in communications applications).

The AD9260 is a 16-bit, high-speed oversampled analog-to-digital converter (ADC) that offers exceptional dynamic range over a wide bandwidth and low power consumption.

The AD9281 is a complete dual channel, 8-bit CMOS ADC with features including dual matching, low power dissipation, single supply, low differential nonlinearity error, on-chip analog input buffers, on-chip reference, high signal-to-noise ratio, no missing codes, etc.

The AD7720 is a 7th-order sigma-delta modulator from Analog Devices that converts the analog input signal into a high-speed 1-bit data stream. The part operates from a +5V supply and accepts a differential input range of 0V to +2.5V or ±1.25V centered about a common-mode bias. The analog input is continuously sampled by the analog modulator, eliminating the need for external sample and hold circuitry. The input information is contained in the output stream as a density of ones. The original information can be reconstructed with an appropriate digital filter. The part provides an accurate on-chip 2.5V reference. A reference input/output function is provided, which allows either the internal or external reference to be used. The AD7720 is a low-power, low-noise, high-speed analog-to-digital converter suitable for a variety of applications.

The AD7731 is a 24-bit sigma-delta ADC with a proprietary programmable gain front end that allows it to accept a range of input signal ranges, including low level signals, directly from a transducer. The part features three buffered differential programmable gain analog inputs.

AD7811/AD7812 is a high speed, low power, 10-bit A/D converter, supports 2.7V-5.5V power supply voltage, and the maximum sampling rate is 350kSPS.
