SGM8261-1/SGM8261-2 Bipolar-Input, High Performance, Ultra-Low Noise Operational Amplifiers
●GENERAL DESCRIPTION
■The single SGM8261-1 and dual SGM8261-2 are bipolar-input, low noise operational amplifiers optimized for high voltage systems. These devices operate from 3.6V to 36V single supply or from ±1.8V to ±18V dual power supplies, while consuming 3.8mA quiescent current per amplifier.
■The SGM8261-1/2 have impressive dynamic characteristics with various loads. The rail-to-rail output swing with a 2kΩ load is within 185mV of the rails. This results in large headroom and wide dynamic range. The SGM8261-1/2 are unity-gain stable and offer a ±65mA high output current. They feature 1.6nV/√Hz ultra-low noise at 1kHz with 0.00002% distortion.
■The SGM8261-1 is available in a Green SOIC-8 package. The SGM8261-2 is available in Green SOIC-8, MSOP-8 and TDFN-3×3-8BL packages. They operate over an ambient temperature range of -40°C to +85°C.
