The SGM8606 is a high-precision and low power CMOS operational amplifier that provides very low offset voltage and zero-drift over time and temperature. One comparator and one low drift voltage reference are integrated with the amplifier.

The miniature, high-precision, low quiescent current amplifier offers high-impedance inputs that have a wide input common mode range 100mV beyond the rails and rail-to-rail output that swings within 14mV of the rails. Single or dual supplies as low as +1.8V (±0.9V) and up to +5.5V (±2.75V) may be used. It is optimized for low voltage, single-supply operation. The amplifier offers excellent CMRR without the crossover associated with traditional complementary input stages. This design results in superior performance for driving analog-to-digital converters (ADCs) without degradation of differential linearity.

The comparator’s input common mode range can be 200mV beyond the supply rails and the integrated voltage reference provides precise threshold in application.

The integrated 1.2V series voltage reference offers low 42μV/℃ drift. It is stable with up to 10nF capacitive load, and can source up to 2mA (TYP) of output current.
