The LTC2664 is a family of four-channel, 16-/12-bit ?10V digital-to-analog converters with integrated precision references. They are guaranteed monotonic and have built-in rail-to-rail output buffers. These SoftSpan? DACs offer five output ranges up to ?10V. The range of each channel is independently programmable, or the part can be hardware-configured for operation in a fixed range.The integrated 2.5V reference is buffered separately to each channel; an external reference can be used for additional range options. The LTC2664 also includes A/B toggle capability via a dedicated pin or software toggle command.The SPI/Microwire-compatible 3-wire serial interface operates on logic levels as low as 1.71V at clock rates up to 50MHz.Applications Optical Networking Instrumentation Data Acquisition Automatic Test Equipment Process Control and Industrial Automation

Demonstration circuit 1342B features the LT3758AEMSE in a 300kHz SEPIC converter circuit, designed for a 24V output from a 18V to 72V input.

The ADA4858-3 (triple) is a single-supply, high speed current feedback amplifier with an integrated charge pump that eliminates the need for negative supplies to output negative voltages or output a 0 V level for video applications. The 600 MHz, ?3 dB bandwidth and 600 V/?s slew rate make this amplifier well suited for many high speed applications. In addition, its 0.1 dB flatness out to 85 MHz at G = 2, along with its differential gain and phase errors of 0.01% and 0.02? into a 150 ? load, make it well suited for professional and consumer video applications.This triple operational amplifier is designed to operate on supply voltages of 3.3 V to 5 V, using only 42 mA of total quiescent current, including the charge pump. To further reduce the power consumption, it is equipped with a power-down feature that lowers the total supply current to as low as 2.5 mA when the amplifier is not being used. Even in power-down mode, the charge pump can be used to power external components. The maximum output current for external use is 50 mA at ?3 V. The amplifier also has a wide input common-mode voltage range that extends from 1.8 V below ground to 1.2 V below the positive rail at a 5 V supply.The ADA4858-3 is available in a 16-lead LFCSP, and it is designed to work over the extended industrial temperature range of ?40?C to +105?C.ApplicationsProfessional videoConsumer videoImagingActive filtersData Sheet, Rev.

The ADF7023 is a very low power, high performance, highly integrated 2FSK/GFSK/OOK/MSK/GMSK transceiver designed for operation in the 862 MHz to 928 MHz and 431 MHz to 464 MHz frequency bands, which cover the worldwide license-free ISM bands at 433 MHz, 868 MHz, and 915 MHz. It is suitable for circuit applications that operate under the European ETSI EN300-220, the North American FCC (Part 15), the Chinese short-range wireless regulatory standards, or other similar regional standards. Data rates from 1 kbps to 300 kbps are supported.The transmit RF synthesizer contains a VCO and a low noise fractional-N PLL with an output channel frequency resolution of 400 Hz. The VCO operates at 2? or 4?, the fundamental frequency to reduce spurious emissions. The receive and transmit synthesizer bandwidths are automatically, and independently, configured to achieve optimum phase noise, modulation quality, and settling time. The transmitter output power is programmable from ?20 dBm to +13.5 dBm, with automatic PA ramping to meet transient spurious specifications. The part possesses both single-ended and differential PAs, which allows for Tx antenna diversity.The receiver is exceptionally linear, achieving an IP3 specification of ?12.2 dBm and ?11.5 dBm at maximum gain and minimum gain, respectively, and an IP2 specification of 18.5 dBm and 27 dBm at maximum gain and minimum gain, respectively. The receiver achieves an interference blocking specification of 66 dB at ?2 MHz offset and 74 dB at ?10 MHz offset. Thus, the part is extremely resilient to the presence of interferers in spectrally noisy environments. The receiver features a novel, high speed, automatic frequency control (AFC) loop, allowing the PLL to find and correct any RF frequency errors in the recovered packet.A patent pending, image rejection calibration scheme is available through a program download. The algorithm does not require the use of an external RF source nor does it require any user intervention once initiated. The results of the calibration can be stored in nonvolatile memory for use on subsequent power-ups of the transceiver.See data sheet for additional information.Applications Smart metering IEEE 802.15.4g Wireless MBUS Home automation Process and building control Wireless sensor networks (WSNs) Wireless healthcare
