The AD7984 is an 18-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD. It contains a low power, high speed, 18-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7984 samples the voltage difference between the IN+ and IN− pins. The voltages on these pins usually swing in opposite phases between 0 V and VREF. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD.The SPI-compatible serial interface also features the ability, using the SDI input, to daisy-chain several ADCs on a single 3-wire bus and provides an optional busy indicator. It is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic, using the separate VIO supply.The AD7984 is available in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +85°C.Applications Automated test equipment Data acquisition systems Medical instruments Machine automation

The AD7991 / AD7995 / AD7999 are 12-/10-/8-bit, low power, successive approximation ADCs with an I2C®-compatible interface. Each part operates from a single 2.7 V to 5.5 V power supply and features a 1 μs conversion time. The track-and-hold amplifier allows each part to handle input frequencies of up to 14 MHz, and a multiplexer allows taking samples from four channels.Each AD7991 / AD7995 / AD7999 provides a 2-wire serial interface compatible with I2C interfaces. The AD7991 and AD7995 come in two versions and each version has an individual I2C address. This allows two of the same devices to be connected to the same I2C bus. Both versions support standard, fast, and high speed I2C interface modes. The AD7999 comes in one version.The AD7991 / AD7995 / AD7999 normally remain in a shutdown state, powering up only for conversions. The conversion process is controlled by a command mode, during which each I2C read operation initiates a conversion and returns the result over the I2C bus.When four channels are used as analog inputs, the reference for the part is taken from VDD; this allows the widest dynamic input range to the ADC. Therefore, the analog input range to the ADC is 0 V to VDD;. An external reference, applied through the VIN3/VREF input, can also be used with this part.PRODUCT HIGHLIGHTS Four single-ended analog input channels, or three single-ended analog input channels and one reference input channel. I2C-compatible serial interface. Standard, fast, and high speed modes. Automatic shutdown.

This family features a high performance sample-and-hold amplifier (SHA) and voltage reference. The AD9215 uses a multistage differential pipelined architecture with output error correction logic to provide 10-bit accuracy at 105 MSPS data rates and to guarantee no missing codes over the full operating temperature range.The wide bandwidth, truly differential sample-and-hold amplifier (SHA) allows for a variety of user-selectable input ranges and offsets including single-ended applications. It is suitable for multiplexed systems that switch full-scale voltage levels in successive channels and for sampling single-channel inputs at frequencies well beyond the Nyquist rate. Combined with power and cost savings over previously available ADCs, the AD9215 is suitable for applications in communications, imaging, and medical ultrasound.A single-ended clock input is used to control all internal conversion cycles. A duty cycle stabilizer compensates for wide variations in the clock duty cycle while maintaining excellent performance. The digital output data is presented in straight binary or twos complement formats. An out-of-range signal indicates an overflow condition, which can be used with the MSB to determine low or high overflow.Fabricated on an advanced CMOS process, the AD9215 is available in both a 28-lead surface-mount plastic package and a 32-lead chip scale package and is specified over the industrial temperature range of −40°C to +85°C.PRODUCT HIGHLIGHTS The AD9215 operates from a single 3 V power supply and features a separate digital output driver supply to accommodate 2.5 V and 3.3 V logic families. Operating at 105 MSPS, the AD9215 core ADC consumes a low 120 mW; at 80 MSPS, the power dissipation is 104 mW; and at 65 MSPS, the power dissipation is 96 mW. The patented SHA input maintains excellent performance for input frequencies up to 200 MHz and can be configured for single-ended or differential operation. The AD9215 is part of several pin compatible 10-, 12-, and 14-bit low power ADCs. This allows a simplified upgrade from 10 bits to 12 bits for systems up to 80 MSPS. The clock duty cycle stabilizer maintains converter performance over a wide range of clock pulse widths. The out of range (OR) output bit indicates when the signal is beyond the selected input range.APPLICATIONS Ultrasound equipment IF sampling in communications receivers Battery-powered instruments Hand-held scopemeters Low cost digital oscilloscopes

A duty cycle stabilizer is provided to compensatefor variations in the ADC clock duty cycle, allowing theconverters to maintain excellent performance.The AD9600 has several functions that simplify the automatedgain control (AGC) function in a communications receiver. Forexample, the fast detect feature allows fast overrange detectionby outputting four bits of input level information with veryshort latency.In addition, the programmable threshold detector allows monitoringthe amplitude of the incoming signal with short latency,using the four fast detect bits of the ADC. If the input signal levelexceeds the programmable threshold, the fine upper thresholdindicator goes high. Because this threshold is set from the fourMSBs, the user can quickly adjust the system gain to avoid anoverrange condition.Another AGC-related function of the AD9600 is the signalmonitor. This block allows the user to monitor the compositemagnitude of the incoming signal, which aids in setting the gainto optimize the dynamic range of the overall system.The ADC output data can be routed directly to the two external10-bit output ports.
