The AD534 is a monolithic laser trimmed four-quadrant multiplier divider having accuracy specifications previously found only in expensive hybrid or modular products. A maximum multiplication error of ±0.25% is guaranteed for the AD534L without any external trimming. Excellent supply rejection, low temperature coefficients and long-term stability of the on-chip thin film resistors and buried Zener reference preserve accuracy even under adverse conditions of use. It is the first multiplier to offer fully differential, high impedance operation on all inputs, including the Z input, a feature that greatly increases its flexibility and ease of use. The scale factor is pretrimmed to the standard value of 10.00 V; by means of an external resistor, this can be reduced to values as low as 3 V.The wide spectrum of applications and the availability of several grades commend this multiplier as the first choice for all new designs. The AD534J (±1% maximum error), AD534K (±0.5% maximum), and AD534L (±0.25% maximum) are specified for operation over the 0°C to +70°C temperature range. The AD534S (±1% maximum) and AD534T (±0.5% maximum) are specified over the extended temperature range, −55°C to +125°C. All grades are available in hermetically sealed TO-100 metal cans and SBDIP packages. AD534K, AD534S, and AD534T chips are also available.APPLICATIONSHigh quality analog signal processingDifferential ratio and percentage computationsAlgebraic and trigonometric function synthesisWideband, high crest rms-to-dc conversionAccurate voltage controlled oscillators and filtersAvailable in chip form

The AD538 is a monolithic real-time computational circuit which provides precision analog multiplication, division, and exponentiation. The combination of low input and output offset voltages and excellent linearity results in accurate computation over an unusually wide input dynamic range. Laser wafer trimming makes multiplication and division with errors as low as 0.25% of reading possible, while typical output offsets of 100 microV or less add to the overall off-the-shelf performance level. Real-time analog signal processing is further enhanced by the device's 400 kHz bandwidth.The AD538's overall transfer function is Vo=Vy(Vz/Vx)m. Programming a particular function is via pin strapping. No external components are required for one-quadrant (positive input) multiplication and division. Two-quadrant (bipolar numerator) division is possible with the use of external level shifting and scaling resistors. The desired scale factor for both multiplication and division can be set using the on-chip +2 V or +10 V references, or controlled externally to provide simultaneous multiplication and division. Exponentiation with an M value from 0.2 to 5 can be implemented with the addition of one or two external resistors. Direct log ratio computation is possible by utilizing only the log ratio and output sections of the chip. Access to the multiple summing junctions adds further to the AD538's flexibility. Finally, a wide power-supply range of ±4.5 V to ±18 V allows operation from standard ±5 V, ± 12 V and ± 15 V supplies. The AD538 is available in two accuracy grades (A and B) over the industrial (-25°C to +85°C) temperature range and one grade (S) over the military (-55°C to +125°C) temperature range. The device is packaged in an 18-pin TO-118 hermetic size-brazed ceramic DIP. A-grade chips are also available.APPLICATIONS One- or two-quadrant multiply/divide Log ratio computation Squaring/square rooting Trigonometric function approximations Linearization via curve fitting Precision AGC Power functions

The AD790 is a fast (45 ns), precise voltage comparator, with a number of features that make it exceptionally versatile and easy to use. The AD790 may operate from either a single +5 V supply or a dual ±15 V supply. In the single-supply mode, the AD790's inputs maybe referred to ground, a feature not found in other comparators. In the dual-supply mode it has the unique ability of handling a maximum differential voltage of 15 V across its input terminals, easing their interfacing to large amplitude and dynamic signals.The device is fabricated using Analog Devices' Complementary Bipolar (CB) process - which gives the AD790's combination of fast response time and outstanding input voltage resolution (1mV max). To preserve its speed and accuracy, the AD790 incorporates a 'low glitch' output stage that does not exhibit the large current spikes normally found in TTL or CMOS output stages. Its controlled switching reduces power supply disturbances that can feed back to the input and cause undesired oscillations. The AD790 also has a latching function which makes it suitable for applications requiring synchronous operation.The AD790 is available in five performance grades. The AD790J and the AD790K are rated over the commercial temperature range of 0°C to 70°C. The AD790a and AD790B are rated over the industrial temperature range of −40°C to +85°C. The AD790S is rated over the military temperature range of −55°C to +125°C and is available to MIL-STD-883B, Rev. C.PRODUCT HIGHLIGHTS The AD790’s combination of speed, precision, versatility and low cost makes it suitable as a general purpose comparator in analog signal processing and data acquisition systems. Built-in hysteresis and a low-glitch output stage minimize the chance of unwanted oscillations, making the AD790 easier to use than standard open-loop comparators. The hysteresis combined with a wide input voltage range enables the AD790 to respond to both slow, low level (e.g., 10 mV) signals and fast, large amplitude (e.g., 10 V) signals. A wide variety of supply voltages is acceptable for operation of the AD790, ranging from single 5 V to dual +5 V/–12 V, ±5 V, or +5 V/±15 V supplies. The AD790’s power dissipation is the lowest of any comparator in its speed range. The AD790’s output swing is symmetric between VLOGIC and ground, thus providing a predictable output under a wide range of input and output conditions.APPLICATIONS Zero-Crossing Detectors Overvoltage Detectors Pulse-Width Modulators Precision Rectifiers Discrete A/D Converters Delta-Sigma Modulator A/Ds
