Demonstration circuit 1568A is a 2A monolithic multichemistry battery charger for solar power applications featuring the LT3652EDD. The LT3652 is a complete mid-power Li-Ion battery charger that can operate over a wide input voltage range. The charger employs a 3.3V float voltage feedback reference that allows the battery float voltage to be adjusted up to 14.4V. The LT3652 has an input voltage regulation loop which reduces charge current if the input falls below a programmed level, set with a resistor divider. The circuit provides CC/CV charging with a 2A maximum charge current that is programmed by a sense resistor.

The AD8153 is an asynchronous, protocol agnostic, single-lane 2:1 switch with three differential CML inputs and three differential CML outputs. The AD8159, another member of the Xstream line of products, is suitable for similar applications that require more than one lane.The AD8153 is optimized for NRZ signaling with data rates of up to 3.2 Gbps per port. Each port offers two levels of input equalization and four levels of output pre-emphasis.The device consists of a 2:1 multiplexer and a 1:2 demultiplexer. There are three operating modes: pin mode, serial mode, and mixed mode. In pin mode, lane switching, equalization, and pre-emphasis are controlled exclusively using external pins. In serial mode, an I2C interface is used to control the device and to provide access to advanced features, such as additional pre- emphasis settings and output disable. In mixed mode, the user accesses the advanced features using I2C, but controls lane switching using the external pins.The main application of the AD8153 is to support redundancy on both the backplane side and the line interface side of a serial link. The device has unicast and bicast capability, so it is capable of supporting either 1 + 1 or 1:1 redundancy.Using a mixture of bicast and loopback modes, the AD8153 can also be used to test high speed serial links by duplicating the incoming data and transmitting it to the destination port and test equipment simultaneously.APPLICATIONS Low cost redundancy switch SONET OC48/SDH16 and lower data rates Gigabit Ethernet over backplane Fibre Channel 1.06 Gbps and 2.12 Gbps over backplane Serial RapidIO PCI Express Gen 1 Infiniband over backplane

The AD5766/AD5767 are 16-channel, 16-bit/12-bit, voltage output denseDAC? digital-to-analog converters (DACs).The DACs generate output voltage ranges from an external 2.5 V reference. Depending on the voltage range selected, the midpoint of the output span can be adjusted, allowing a minimum output voltage as low as ?20 V or a maximum output voltage of up to +14 V. Each of the 16 channels can be monitored with an integrated output voltage multiplexer.The AD5766/AD5767 have integrated output buffers that can sink or source up to 20 mA. In conjunction with these buffers, a low frequency signal can be superimposed onto each DAC output via dedicated dither pins. These dedicated dither pins simplify the system design by reducing the number of external components required for a similar external implementation, like operational amplifiers or resistors. The reduction of external components makes the AD5766/AD5767 suitable for indium phosphide Mach Zehnder modulator (InP MZM) biasing applications.The devices incorporate a power-on reset (POR) circuit that ensures that the DAC outputs are clamped to ground on power up and remain at this level until the output range of the DAC is configured. The outputs of all DACs are updated through register configuration, with the added functionality of user-selectable DAC channels to be simultaneously updated.The AD5766/AD5767 use a versatile 4-wire serial interface that operates at clock rates of up to 50 MHz for write mode and is compatible with serial peripheral interface (SPI), QSPI?, MICROWIRE?, and DSP interface standards. The AD5766/ AD5767 also contain a VLOGIC pin intended for 1.8 V/3.3 V/5 V logic.The AD5766/AD5767 are available in a 4 mm ? 4 mm WLCSP package and a 40-lead LFCSP package. The AD5766/AD5767 operate at a temperature range of ?40?C to +105?C.Applications Mach Zehnder modulator bias control Optical networking Instrumentation Industrial automation Data acquisition systems Analog output modules

The AD7170 is a very low power 12-bit analog-to-digital converter (ADC). It contains a precision 12-bit sigma-delta (?-?) ADC and an on-chip oscillator. Consuming only 135 ?A, the AD7170 is particularly suitable for portable or battery operated products where very low power is a requirement. The AD7170 also has a power-down mode in which the device consumes 5 ?A, thus increasing the battery life of the product.For ease-of-use, all the features of the AD7170 are controlled by dedicated pins. Each time a data read occurs, eight status bits are appended to the 12-bit conversion. These status bits contain a pattern sequence that can be used to confirm the validity of the serial transfer.The output data rate of the AD7170 is 125 Hz, whereas the settling time is 24 ms. The AD7170 has one differential input and a gain of 1. This is useful in applications where the user needs to use an external amplifier to implement system-specific filtering or gain requirements.The AD7170 operates with a power supply from 2.7 V to 5.25 V. It is available in a 10-lead LFCSP package.The AD7171 is a 16-bit version of the AD7170. It has the same feature set as the AD7170 and is pin-for-pin compatible.INTERFACE 2-wire serial (read-only device) SPI compatible Schmitt trigger on SCLKAPPLICATIONS Pressure measurement Industrial process control Portable instrumentation

The AD7091R-5 operates from a single 2.7 V to 5.25 V power supply and typically consumes only 24 ?A at a 3 V supply in fast mode.?The AD7091R-5 provides a 2-wire serial interface compatible with I2C interfaces. The conversion process can be controlled by a sample mode via the CONVST pin, an autocycle mode selected through software control, or a command mode in which conversions occur across I2C write operations.The device contains a wide bandwidth track-and-hold amplifier that can handle input frequencies up to 1.5 MHz. The AD7091R-5 also features an on-chip conversion clock, an on-chip accurate 2.5 V reference, and a programmable out-of-bounds user alert function.The AD7091R-5 offers four single-ended analog input channels with a channel sequencer that allows a preprogrammed selection of channels to be converted sequentially.The AD7091R-5 uses advanced design techniques to achieve ultralow power dissipation without compromising performance. It also features flexible power management options. An on-chip configuration register allows the user to set up different operating conditions. These include power management, alert functionality, busy indication, channel sequencing, and general-purpose output pins.
