The AD830 is a wideband, differencing amplifier designed for use at video frequencies but also useful in many other applications. It accurately amplifies a fully differential signal at the input and produces an ouput voltage referred to a user-chosen level. The undesired common-mode signal is rejected, even at high frequencies. High impedance input ease interfacing to finite source impedances and thus preserve the excellent common-mode rejection. In many respects, it offers significant improvements over discrete difference amplifier approaches, in particular in high frequency common-mode rejection.  The wide common-mode and differential-voltage range of the AD830 make it particularly useful and flexible in level shifting applications, but at lower power dissipation than discrete solutions. Low distortion is preserved over the many possible differential and common-mode voltages at the input and output.Good gain flatness and excellent differential gain of 0.06% and phase of 0.08° make the AD830 suitable for many video system applications. Furthermore, the AD830 is suited for general purpose signal processing from dc to 10 MHz.APPLICATIONS Differential line receiver High speed level shifter High speed in-amp Differential to single-ended conversion Resistorless summation and subtraction High speed analog-to-digital converter

Four precision independent comparators comprise the CMP04. Performance highlights include a very low offset voltage, low output saturation voltage and high gain in a single supply design. The input voltage range includes ground for single supply operation and V- for split supplies.

Maximum logic interface flexibility is offered by the open-collector TTL output.

The OP282/OP482 dual and quad operational amplifiers feature excellent speed at exceptionally low supply currents. Slew rate exceeds 7 V/µs with supply current under 250 µA per amplifier. these unity gain stable amplifiers have a typical gain bandwidth of 4 MHz.The JFET input stage of the OP282/OP482 insures bias current is typically a few piocamps and below 500 pA over the full temperature range. Offset voltage is under 3 mV for the dual and under 4 mV for the quad.With a wide output swing, within 1.5 volts of each supply, low power consumption and high slew rate, the OP282/OP482 are ideal for battery-powered systems or power restricted applications.

The OP37 provides the same high performance as the OP27, but the design is optimized for circuits with gains greater than five. This design change increases slew rate to 17V/µsec and gain-bandwidth product to 63MHz.The OP37 provides the low offset and drift of the OP07 plus higher speed and lower noise. Offsets down to 25µV and drift of 0.6µV/°C maximum make the OP-37 ideal for precision instrumentation applications. Exceptionally low noise (en=3.5nV/Hz at 10Hz), a low 1/f noise corner frequency of 2.7Hz, and the high gain of 1.8 million, allow accurate high-gain amplification of low-level signals.The low input bias current of ±10nA and offset current of 7nA are achieved by using a bias-current-cancellation circuit. Over the military temperature range this typically holds IB and IOS to ±20nA and 15nA respectively. The output stage has good load driving capability. A guaranteed swing of ±10V into 600 Ohm and low output distortion make the OP37 an excellent choice for professional audio applications.

The OP-42 is a fast precision JFET-input operational amplifier.Similar in speed to the OP-17, the OP-42 offers a symmetric 58V/µs slew rate and is internally compensated for unity-gain operation. OP-42 speed is achieved with a supply current of less than 6mA. Unity gain stability, a wide full-power bandwidth of 900kHz, and a fast settling-time of 800ns to 0.01% make the OP-42 an ideal output amplifier for fast digital-to-analog converters. Equal attention was given to both speed and precision in the OP-42 design.Its tight 750µV maximum input offset voltage combined with well-controlled drift of less than 10µV/%C eliminates the need for external nulling in many circuits. The common-mode rejection of the 88dB minimum over a ±11 V input voltage range is exceptional for a high-speed amplifier. High CMR combined with a minimum 500V/mV gain into 10k(ohm) load ensure excellent linearity in both noninverting and inverting gain configurations. The low input bias and offset currents provided by the JFET input stage suit the OP-42 for use in high-speed sample and hold circuits, peak detectors, and log amplifiers. Excellent radiation hardness characteristics make the OP-42 ideal for military and aerospace applications.The OP-42 conforms to the standard 741 pinout with nulling to V-.

Outputs are stable with capacitive loads of over 1000pF. Supply current is less than 300 μA per amplifier at 5 V. 500 Ω series resistors protect the inputs, allowing input signal levels several voltsabove the positive supply without phase reversal.

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.
