    SGM8958-1

    GENERAL DESCRIPTION

    The single SGM8958-1 and dual SGM8958-2 CMOS operational amplifiers provide very low offset voltage and zero-drift over time and temperature.

    The miniature, high precision, low quiescent current amplifiers offer high-impedance inputs that have a wide input common mode range of 100mV beyond the rails and rail-to-rail output that swings within 5mV of the rails. Single or dual supplies as low as 1.8V (±0.9V) and up to 5.5V (±2.75V) may be used. They are optimized for low voltage, single-supply operation.

    The SGM8958-1/2 offer 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 single SGM8958-1 is available in Green SOT-23-5, SC70-5 and SOIC-8 packages. The dual SGM8958-2 is available in Green SOIC-8 and TDFN-3×3-8L packages. They are specified over -40 to +125 temperature range.
