Description
The HA-2556 is a monolithic, high speed, four quadrant, analog multiplier constructed in the Intersil Dielectrically Isolated High Frequency Process.
The voltage output simplifies many designs by eliminating the current-to-voltage conversion stage required for current output multipliers.
The HA-2556 provides a 450V/μs slew rate and maintains 52MHz and 57MHz bandwidths for the X and Y channels respectively, making it an ideal part for use in video systems.
The suitability for precision video applications is demonstrated further by the Y-Channel 0.1dB gain flatness to 5.0MHz, 1.5% multiplication error, -50dB feedthrough and differential inputs with 8μA bias current. The HA-2556 also has low differential gain (0.1%) and phase (0.1°) errors.
The HA-2556 is well suited for AGC circuits as well as mixer applications for sonar, radar, and medical imaging equipment.
The HA-2556 is not limited to multiplication applications only; frequency doubling, power detection, as well as many other configurations are possible.

Genaral Descroption
The ISL6323 dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6323 supports hybrid power control of AMD processors which operate from either a 6-bit parallel VID interface (PVI) or a serial VID interface (SVI). The dual output ISL6323 features a multi-phase controller to support uniplane VDD core voltage and a single phase controller to power the Northbridge (VDDNB) in SVI mode. Only the multi-phase controller is active in PVI mode to support uniplane VDD only processors.
A precision uniplane core voltage regulation system is provided by a two-to-four-phase PWM voltage regulator (VR) controller. The integration of two power MOSFET drivers, adding flexibility in layout, reduce the number of external components in the multi-phase section. A single phase PWM controller with integrated driver provides a second precision voltage regulation system for the North Bridge portion of the processor. This monolithic, dual controller with integrated driver solution provides a cost and space saving power management solution.
For applications which benefit from load line programming to reduce bulk output capacitors, the ISL6323 features output voltage droop. The multi-phase portion also includes advanced control loop features for optimal transient response to load application and removal. One of these features is highly accurate, fully differential, continuous DCR current sensing for load line programming and channel current balance. Dual edge modulation is another unique feature,
allowing for quicker initial response to high di/dt load transients.

ACS04MS - Radiation Hardened Hex Inverter

The Intersil ISL84467 device is a low ON-resistance, low voltage, bidirectional, Quad SPDT (Dual DPDT) analog switch designed to operate from a single +1.65V to +4.5V supply.
Targeted applications include battery powered equipment that benefit from low rON (0.39Ω) and fast switching speeds (tON = 33ns, tOFF = 16ns).
The digital logic input is 1.8V logic-compatible when using a single +3V supply.
With a supply voltage of 4.2V and logic high voltage of 2.85V at both logic inputs, the part draws only 12μA max of ICC current.
Cell phones, for example, often face ASIC functionality limitations.
The number of analog input or GPIO pins may be limited and digital geometries are not well suited to analog switch performance.
This part may be used to “mux-in” additional functionality while reducing ASIC design risk.
The ISL84467 is offered in small form factor package, alleviating board space limitations.
The ISL84467 consists of four SPDT switches.
It is configured as a dual double-pole/double-throw (DPDT) device with two logic control inputs that control two SPDT switches each.
The configuration can be used as a dual differential 2-to-1 multiplexer/demultiplexer.
