The AD7982 is an 18-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD. The AD7982 contains a low power, high speed, 18-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7982 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, VREF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput.The serial peripheral interface (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. The AD7982 is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic, using the separate VIO supply.The AD7982 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 ?s 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.

Theconversion process can be controlled using the CONVST pin,by a command mode where conversions occur across I2C writeoperations or an automatic conversion interval mode selectedthrough software control. The AD7997 / AD7998 require an external reference that shouldbe applied to the REFIN pin and can be in the range of 1.2 V toVDD. This allows the widest dynamic input range to the ADC. On-chip limit registers can be programmed with high andlow limits for the conversion result, and an open-drain, out-of-range indicator output (ALERT) becomes active when theprogrammed high or low limits are violated by the conversionresult. This output can be used as an interrupt.PRODUCT HIGHLIGHTS 2 ?s conversion time with low power consumption. I2C-compatible serial interface with pin-selectable addresses.

The AD8452 combines a precision analog front-end controller and switch mode power supply (SMPS), pulse-width modulator (PWM) driver into a single silicon platform for high volume battery testing and formation manufacturing. A precision instrumentation amplifier (in-amp) measures the battery charge/discharge current, while an equally accurate difference amplifier measures the battery voltage. Internal laser trimmed resistor networks establish the in-amp and difference amplifier gains (66 V/V and 0.4 V/V, respectively), and stabilize the AD8452 performance across the rated operating temperature range.Desired battery cycling current and voltage levels are established by applying precise control voltages to the ISET and VSET inputs. Actual charge and discharge current levels are sensed (usually by a high power, highly accurate shunt resistor) whose value is carefully selected according to system parameters. Switching between constant current (CC) and constant voltage (CV) loop integration is instantaneous, automatic, and completely transparent to the observer. A logic high at the MODE input selects the charge or discharge mode (high for charge, low for discharge).The AD8452 simplifies designs by providing excellent performance, functionality, and overall reliability in a space saving 48-lead, 7 mm ? 7 mm ? 1.4 mm LQFP package rated for operation at temperatures from ?40?C to +85?C.Applications Battery formation and testing High efficiency battery test systems with recycle capability Battery conditioning (charging and discharging) systems

The ADA4350 is an analog front end for photodetectors or othersensors whose output produces a current proportional to thesensed parameter or voltage input applications where the systemrequires the user to select between very precise gain levels tomaximize the dynamic range.The ADA4350 integrates a FET input amplifier, a switching network,and an ADC driver with all functions controllable via a serialperipheral interface (SPI) or parallel control logic into a singleIC. The FET input amplifier has very low voltage noise and currentnoise making it an excellent choice to work with a wide range ofphotodetectors, sensors, or precision data acquisition systems.Its switching network allows the user individual selection of upto six different, externally configurable feedback networks; byusing external components for the feedback network, the usercan more easily match the system to their desired photodetector orsensor capacitance. This feature also allows the use of low thermaldrift resistors, if required.The design of the switches minimizes error sources so that theyadd virtually no error in the signal path. The output driver canbe used in either single-ended or a differential mode and isideal for driving the input of an ADC.The ADA4350 can operate from a single +3.3 V supply or a dual?5 V supply, offering user flexibility when choosing the polarity ofthe detector. It is available in a Pb-free, 28-lead TSSOP package andis specified to operate over the ?40?C to +85?C temperature range.Multifunction pin names may be referenced by their relevantfunction only.Applications Current to voltage (I to V) conversions Photodiode preamplifiers Chemical analyzers Mass spectrometry Molecular spectroscopy Laser/LED receivers Data acquisition systems
