AD7988-516-Bit Lower Power PulSAR ADCs in MSOP/LFCSP | Data Acquisition | 3 | Active | TheAD7988-1/AD7988-5 are 16-bit, successive approximation, analog-to-digital converters (ADC) that operate from a single power supply, VDD. The AD7988-1 offers a 100 kSPS throughput, and the AD7988-5 offers a 500 kSPS throughput. They are low power, 16-bit sampling ADCs with a versatile serial interface port. On the CNV rising edge, they sample an analog input, IN+, between 0 V to VREFwith respect to a ground sense, IN−. 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 to daisy-chain several ADCs on a single 3-wire bus using the SDI input. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic using the separate supply, VIO.The AD7988-1/AD7988-5 generics are housed in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +125°C.ApplicationsAutomated test equipmentData acquisition systemsMedical instrumentsMachine automation |
AD7989-518-Bit, 100 kSPS PulSAR ADCs in MSOP/LFCSP | Integrated Circuits (ICs) | 4 | Active | TheAD7989-1/AD7989-5 are 18-bit, successive approximation, analog-to-digital converters (ADCs) that operate from a single power supply, VDD. The AD7989-1/AD7989-5 contain a low power, high speed, 18-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7989-1/AD7989-5 sample the voltage difference between the IN+ and IN− pins. The voltages on these pins typically swing in opposite phases between 0 V and VREF. The reference voltage, VREF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput.The AD7989-1/AD7989-5 are serial peripheral interface (SPI)-compatible, which features the ability, using the SDI/CSinput, to daisy-chain several ADCs on a single 3-wire bus. The AD7989-1/AD7989-5 are compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic, using the separate VIO supply.The AD7989-1/AD7989-5 are available in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +85°C.ApplicationsAutomated test equipmentData acquisition systemsMedical instrumentsMachine automation |
AD79914-Channel, 12-Bit ADC with I2C Compatible Interface in 8-Lead SOT-23 | Data Acquisition | 3 | Active | The AD7991 /AD7995/AD7999are 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/VREFinput, can also be used with this part.PRODUCT HIGHLIGHTSFour 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.Reference derived from the power supply or external reference.8-lead SOT-23 package.APPLICATIONSSystem monitoringBattery-powered systemsData acquisitionMedical instruments |
