The AD5546 / AD5556 are precision 16-/14-bit, multiplying, low power, current output, parallel input D/A converters. They operate from a single 2.7 V to 5.5 V supply with ±10 V multiplying references for 4-quadrant outputs. Built-in 4-quadrant resistors facilitate the resistance matching and temperaturetracking that minimize the number of components needed for multiquadrant applications. The feedback resistor (RFB) simplifies the I-V conversion with an external buffer. The AD5546/AD5556 are packaged in compact TSSOP-28 packages with operating temperatures from –40°C to +125°C.APPLICATIONS Automatic test equipment Instrumentation Digitally controlled calibration Digital waveform generation

The AD5330 / AD5331 / AD5340 / AD5341 are single 8-/10-/12-bit DACs. They operate from a 2.5 V to 5.5 V supply consuming just 115 μA at 3 V and feature a power-down mode that further reduces the current to 80 nA. The devices incorporate an on-chip output buffer that can drive the output to both supply rails, but the AD5330, AD5340, and AD5341 allow a choice of buffered or unbuffered reference input.The AD5330 / AD5331 / AD5340 / AD5341 have a parallel interface. CS selects the device and data is loaded into the input registers on the rising edge of WR. The GAIN pin allows the output range to be set at 0 V to VREF or 0 V to 2 × VREF.Input data to the DACs is double-buffered, allowing simultaneous update of multiple DACs in a system using the LDAC pin.An asynchronous CLR input is also provided, which resets the contents of the input register and the DAC register to all zeros. These devices also incorporate a power-on reset circuit that ensures that the DAC output powers on to 0 V and remains there until valid data is written to the device.The AD5330 / AD5331 / AD5340 / AD5341 are available in thin shrink small outline packages (TSSOP).APPLICATIONS Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators Industrial process control

The AD76871 is a 16-bit, charge redistribution, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.3 V to 5.5 V. It contains a low power, high speed, 16-bit sampling ADC with no missing codes, an internal conversion clock, and a versatile serial interface port. The device also contains a low noise, wide bandwidth, short aperture delay track-and-hold circuit. On the CNV rising edge, the AD7687 the samples the voltage difference between IN+ and IN− pins, which can range from −VREF to +VREF. The reference voltage, VREF, is applied externally and can be set up to the supply voltage.The power consumption of the device scales linearly with throughput.The SPI-compatible serial interface also features the ability to daisy-chain several ADCs on a single 3-wire bus and provides an optional BUSY indicator by means of the SDI pin. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic using the separate supply VIO.The AD7687 comes in a 10-lead MSOP or a 10-lead LFCSP with operation specified from −40°C to +85°C.APPLICATIONS Battery-powered equipment Data acquisitions Instrumentation Medical instruments Process controls

The HMC835LP6GE is a low noise, wide band, Fractional-N PLL that features an integrated VCO with a fundamental frequency of 2020 to 4100 MHz, and an integrated VCO Output Divider (divide by 2/4/6/.../60/62) that together enable the HMC835LP6GE to generate frequencies from 33 MHz to 4100 MHz. Integrated Phase Detector (PD) and a deltasigma modulator capable of operating at up to 100 MHz enable wider loop-bandwidths, faster frequency changes along with excellent spectral performance.Two independent RF outputs, with independent gain control, enable the HMC835LP6GE to distribute identical frequency and phase signals to multiple destinations, at optimal signal levels tailored to each output.External VCO input, allows the HMC835LP6GE to lock external VCOs, and enables cascaded LO architectures for MIMO radio applications. Two separate Charge Pump (CP) outputs enable separate loop filters optimized for both integrated and external VCOs, and seamless switching between integrated or external VCOs during operation. Programmable RF output phase feature can further phase adjust and synchronize multiple HMC835LP6GEs enabling scalable MIMO and beam-forming radio architectures.Additional features include configurable output mute function that mutes RF outputs during frequency changes, Exact Frequency Mode that enables the HMC835LP6GE to generate fractional frequencies with 0 Hz frequency error, and the ability to synchronously change frequencies without changing the phase of the output signal.Applications MIMO Radio Architectures Cellular Infrastructure Cellular backhaul Communications Test Equipment CATV Equipment Phased Array Applications?
