The AD704JNZ from Analog Devices is a dual-precision, low-power operational amplifier using super-beta input transistors to achieve very low input bias current of 1nA typical while drawing only 25μA supply current per amplifier. The device operates from dual supplies of ±4V to ±18V and features a maximum input offset voltage of 400μV (J grade). The super-beta transistor input stage provides the low bias current of a BiFET amplifier without the speed limitations and input voltage noise of JFET designs. The AD704 is a functional upgrade for industry-standard dual op-amps such as the LM358 and LT1013, offering better DC precision and lower supply current in the same pinout.

The AD704 operates using a super-beta bipolar input stage. (1) The input differential pair uses super-beta NPN transistors with current gain (beta) of 1000-5000, compared to 100-500 for standard bipolar transistors. This dramatically reduces the input bias current to 1nA typical while maintaining the low offset voltage and low noise characteristics of bipolar technology. (2) The gain stage provides the high open-loop voltage gain needed for precision amplification, with the overall amplifier compensated for unity-gain stability by an internal 30pF capacitor. (3) The output stage can drive loads to within 2V of either supply rail, with short-circuit protection and no phase reversal when the inputs are overdriven beyond the common-mode range. The low 25μA supply current per amplifier makes it ideal for battery-powered applications.
