The AD648 is a matched pair of low power, precision monolithic operational amplifiers. It offers both low bias current (10 pA max, warmed up) and low quiescent current (400 µA max) and is fabricated with ion-implanted FET and laser wafer trimming technologies. Input bias current is guaranteed over the AD648's entire common-mode voltage range.The economical J grade has a maximum guaranteed offset voltage of less than 2 mV and an offset voltage drift of less than 20 µV/°C. The combination of low quiescent current and low offset voltage drift minimizes changes in input offset voltage due to self-heating effects. The AD648 is recommended for any dual supply op amp application requiring low power and excellent dc and ac performance. In applications such as battery-powered, precision instrument front ends and CMOS DAC buffers, the AD648's excellent combination of low input offset voltage and drift, low bias current and low 1/f noise reduces output errors. High common-mode rejection and high open-loop gain ensures better than 12-bit linearity in high impedance, buffer applications.The AD648 is pinned out in a standard dual op amp configuration and is available in seven performance grades. The AD648J and AD648K are rated over the commercial temperature range of 0°C to +70°C. The AD648 is available in an 8-pin plastic mini-DIP and SOIC package.

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
