The AD826ANZ from Analog Devices is a High-Speed Dual-Channel Operational Amplifier that has been designed to drive heavy capacitive and resistive loads. It requires a supply voltage from -18 V to +18 V, an input offset current of 25 nA, and an input bias current of 3.3 nA. This amplifier provides an output current of over 50 mA and an open loop gain of 4 V/mV. It has a common mode rejection ratio (CMRR) of 100 dB. This op-amp is ideal for use in applications that require unity gain stability and high output drive capability, such as buffering and cable driving. It consists of a degenerated NPN differential-pair driving matched PNPs in a folded-cascade gain stage. This amplifier uses Class AB-based emitter followers at the output buffer to deliver the necessary current to the load while maintaining low levels of distortion. It ensures an excellent DC and good video performance over the operating temperature range.
This op-amp is available in a through-hole package that measures 0.4 x 0.28 x 0.210 inches and is ideal for unity gain ADC/DAC buffer, cable drivers, 8/10-bit data acquisition systems, video line drivers, active filters, video cameras, and portable instrumentation applications.
