The Maxim Integrated ICL7612DCSA+ is a single general-purpose CMOS op-amp in an 8-SOIC package. It delivers rail-to-rail output swing and operates from a 2V to 16V single or split supply, making it a fit for battery-powered instrumentation, sensor buffers, and low-frequency signal conditioning where supply headroom is tight. The 1.4 MHz gain-bandwidth product and 1.6V/µs slew rate cover audio-band filtering and moderate-speed ADC drivers, but not fast pulse or video paths.
Minimum supply is 2 V and maximum is 16 V. The rail-to-rail output stage preserves dynamic range at low voltages.
1 pA input bias and 15 mV offset — DC performance reality
Input bias current is 1 pA typical, a benefit of the CMOS input stage, so high-source-impedance sensors (photodiodes, pH probes) see negligible loading. The 15 mV input offset voltage is typical for a general-purpose CMOS op-amp — adequate for AC-coupled or non-precision DC paths, but not for microvolt-level strain-gauge or thermocouple amplification without auto-zero or chopper-stabilized alternatives.
