Analog Devices Inc.The ADF4150HV is a 3.0 GHz, fractional-N or integer-N frequency synthesizer with an integrated high voltage charge pump. The synthesizer can be used to drive external wideband VCOs directly, eliminating the need for operational amplifiers to achieve higher tuning voltages. This simplifies design and reduces cost while improving phase noise, in contrast to active filter topologies, which tend to degrade phase noise compared to passive filter topologies.The VCO frequency can be divided by 1, 2, 4, 8, or 16 to allow the user to generate RF output frequencies as low as 31.25 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin- and software-controllable.A simple 3-wire interface controls all on-chip registers. The charge pump operates from a power supply ranging from 6 V to 30 V, whereas the rest of the device operates from 3.0 V to 3.6 V.

EVAL-ADG5421FEBZ
Analog Devices Inc.The ADG5421F is a dual SPST, low on resistance switch that features overvoltage protection, power-off protection, and overvoltage detection on the source pins. When no power supplies are present, the switch remains in the off condition, and the switch inputs are high impedance. When powered, if the analog input signal levels on either of the Sx pins exceed VDD or VSS by the threshold voltage, VT, both switches turn off together, and the open-drain fault flag (FF) pin pulls to a logic low. Input signal levels up to +60 V or ?60 V relative to ground are blocked in both the powered and unpowered condition. The switches turn on with a Logic 1 input and conduct equally well in both directions. The digital input is compatible with 1.8 V logic inputs over the full operating supply range.

EVAL-ADG5462FEBZ
Analog Devices Inc.The ADG5462F contains four channels that are overvoltage protected. The channel protector is placed in series with the signal path and protects sensitive components from overvoltage faults in that path. The channel protector prevents overvoltages when powered and unpowered, and it is ideal for use in applications where correct power supply sequencing cannot always be guaranteed. The primary supply voltages define the on-resistance profile, while the secondary supply voltages define the voltage level at which the overvoltage protection engages.When no power supplies are present, the channel remains in the off condition, and the channel inputs are high impedance. Under normal operating conditions, if the analog input signal levels on any Sx pin exceed positive fault voltage (POSFV) or negative fault voltage (NEGFV) by a threshold voltage (VT), the channel turns off and that Sx pin becomes high impedance. If the DR pin is driven low, the drain pin (Dx) is pulled to the secondary supply voltage that was exceeded. The output profile for each DR voltage level is shown in Figure 1. Input signal levels up to ?55 V or +55 V relative to ground are blocked in both the powered and unpowered conditions.The low on-resistance of these switches, combined with the on-resistance flatness over a significant portion of the signal range make them an ideal solution for data acquisition and instrumentation applications where excellent linearity and low distortion are critical.Product Highlights Source pins are protected against voltages greater than the secondary supply rails (POSFV and NEGFV), up to ?55 V and +55 V. In an unpowered state, source pins (Sx) are protected against voltages from ?55 V to +55 V. Overvoltage detection with digital output indicates operating state of channel. Trench isolation guards against latch-up. Optimized for low on-resistance and on-resistance flatness.

When powered, if the analog input signal levels on the Sx pins exceed VDD or VSS by a threshold voltage, VT, the switch automatically turns off and the digital FF (fault flag) pin drops to a logic low to indicate a fault.Input signal levels up to +60 V or ?60 V relative to ground are blocked, in both the powered and unpowered condition.
