The AD5172 / AD5173?are dual-channel, 256-position, one-time programmable (OTP) digital potentiometers that employ fuse link technology to achieve memory retention of resistance settings. The digital potentiometer, VR, and RDAC terms are used interchangeably. OTP is a cost-effective alternative to EEMEM for users who do not need to program the digital potentiometer setting in memory more than once. These devices perform the same electronic adjustment function as mechanical potentiometers or variable resistors but with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance.TheAD5172 / AD5173 are programmed using a 2-wire, I2C-compatible digital interface. Unlimited adjustments are allowed before permanently setting the resistance value. During OTP activation, a permanent blow fuse command freezes the wiper position (analogous to placing epoxy on a mechanical trimmer).Unlike traditional OTP digital potentiometers, the AD5172 / AD5173 have a unique temporary OTP overwrite feature that allows for new adjustments even after a fuse is blown. However, the OTP setting is restored during subsequent power-up conditions. This allows users to treat these digital potentiometers as volatile potentiometers with a programmable preset.APPLICATIONS Systems calibration Electronics level setting Mechanical trimmers replacement in new designs Permanent factory PCB setting Transducer adjustment of pressure, temperature, position, chemical, and optical sensors RF amplifier biasing Gain control and offset adjustment

The AD9530 is a fully integrated PLL and distribution supporting, clock cleanup, and frequency translation device for 40 Gbps/ 100 Gbps OTN applications. The internal PLL can lock to one of two reference frequencies to generate four discrete output frequencies up to 2.7 GHz.The AD9530 features an internal 5.11 GHz to 5.4 GHz, ultralow noise voltage controlled oscillator (VCO). All four outputs are individually divided down from the internal VCO using two high speed VCO dividers (the Mx dividers) and four individual 8-bit channel dividers (the Dx dividers). The high speed VCO dividers offer fixed divisions of 2, 2.5, 3, and 3.5 for wide coverage of possible output frequencies. The AD9530 is configurable for loop bandwidths <15 kHz to attenuate reference noise.The AD9530 is available in a 48-lead LFCSP and operates from a single 2.5 V typical supply voltage.The AD9530 operates over the extended industrial temperature range of ?40?C to +85?C.?Applications 40 Gbps/100 Gbps optical transport network (OTN) line side clocking Clocking of high speed analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) Data communications

The ADG901/ADG902 are wideband switches that use a complementary metal-oxide semiconductor (CMOS) process to provide high isolation and low insertion loss to 1 GHz. The ADG901 is an absorptive (matched) switch with 50 ? terminated shunt legs, while the ADG902 is a reflective switch. These devices are designed such that the isolation is high over the dc to 1 GHz frequency range. These switches enable the user to pass dc signals up to 0.5 V without the use of a dc blocking capacitor. They have on-board CMOS control logic, thus eliminating the need for external controlling circuitry. The control inputs are both CMOS and LVTTL compatible. The low power consumption of these CMOS devices makes them ideally suited to wireless applications and general-purpose high frequency switching.Product Highlights 40 dB Off Isolation at 1 GHz 0.8 dB Insertion Loss at 1 GHz 17 dBm P1dB at 1 GHzApplications Wireless communications General purpose RF switching Dual-band applications High speed filter selection Digital transceiver front-end switch IF switching Tuner modules Antenna diversity switching list

The AD1938 is a high performance, single-chip codec that provides four analog-to-digital converters (ADCs) with input and eight digital-to-analog converters (DACs) with single-ended output using the Analog Devices, Inc., patented multibit sigma-delta (?-?) architecture. An SPI port is included, allowing a microcontroller to adjust volume and many other parameters.The AD1938 operates from 3.3 V digital and analog supplies. The AD1938 is available in a 48-lead (single-ended output) LQFP package. Other members of this family include a differential DAC output and I2C? control port version.The AD1938 is designed for low EMI. This consideration is apparent in both the system and circuit design architectures. By using the on-board PLL to derive the master clock from the LR clock or from an external crystal, the AD1938 eliminates the need for a separate high frequency master clock and can also be used with a suppressed bit clock. The DACs and ADCs are designed using the latest Analog Devices continuous time architectures to further minimize EMI. By using 3.3 V supplies, power consumption is minimized, further reducing emissions.APPLICATIONS Automotive audio systems Home Theater Systems Set-top boxes Digital audio effects processors

Demonstration circuit 1855A is a dual, micropower, low noise and low dropout voltage linear regulator featuring the LT3030. The input voltages are independent for each channel of DC1855A and can range from 2.2V to 20V. Each channel has a jumper that sets the output voltage to either 1.5V, 1.8V, 2.5V, 3.3V, 5V or a voltage that is user-programmed by the installation of a resistor. For channel 1 and channel 2, the maximum output currents are 750mA and 250mA and the ceramic output capacitors are 22μF and 10μF respectively. The internal reference of each channel is bypassed with a 10nF capacitor for reduced output noise. Each channel has a jumper for shutdown and a terminal for PWRGD that is pulled up to the input supply. A resistor divider can be easily added that allows precise lockout at low input voltages.
