These devices can process signals over a wide frequency range, from DC to over 500MHz, and with varying degrees of accuracy, from 0.4% full scale to 2% full scale, depending on the device selected. Most of these devices are referred to as O4-quadrant multipliers,O meaning that these devices can accept any combination of input signal polarity and provide output signals of appropriate polarity. Analog Multipliers can be used to implement a wide variety of signal processing functions including modulation and demodulation, fixed and variable remote gain adjustment, power measurement and mathematical operations in analog computing, curve fitting and linearizing.

The AD630 is a fast, flexible switched dual-input op amp with an on-chip comparator. The AD630 is intended to operate in wide-band, low level and wide-dynamic range instrumentation applications and coherent systems. The AD630 is capable of many analog signal processing functions such as balanced modulation and demodulation, phase detection, square-wave multiplication, absolute-value amplification, and two-channel precision multiplexing. It can also be used as a lock-in amplifier, synchronous detector, rectifier, and much more. The AD630 essentially provides a complete, solution, with on-chip scaling resistors and requires little or no additional circuitry. Mfr.Os Type Unity Gain Channel BW Typ.

Logarithmic amplifiers like the AD606 and the AD640 provide an output voltage proportional to the logarithm of the input voltage for signals from dc to 120 MHz. Variable gain amplifiers like the AD600/602 and AD603 use a patented X-AMP technology which allows the amplifier gain to be varied as the dynamic range of the input signal changes. Logarithmic amplifiers are excellent in all applications that require compression of wide-range analog input data. Variable gain amplifiers are typically employed as fast-response automatic gain control (AGC) elements in RF and IF systems. Alternatively, they can be used to provide time gain control (TGC) in applications such as commercial sonar. Variable Gain Amplifiers Mfr.Os Type Gain Range Gain Accuracy Max. Bandwidth Typ.

Interface Products The ADM2XXL family is designed to meet the EIA-232E specifications while operating from a single +5 V power supply. This is achieved by the use of an on-chip voltage doubler. Older generation RS-232 drivers required three separate power supplies: +5 V, +12 V, and 12 V, resulting in large bulky power supply units. Linear voltage regulators tend to be inefficient and are wasteful of power. This is especially a problem in todayOs portable equipment which operates with battery powered supplies. Ideally the single power supply should be used which can easily be derived from a battery pack. A new design, Analog DevicesO process for the 5 V RS-232 market offers lowest ICC, lowest I shutdown and the highest speed in its class. Our ADM23XL series of line drivers/receivers are major upgrades.
