SGM8261-1/SGM8261-2

Bipolar-Input, High Performance,

Ultra-Low Noise Operational Amplifiers

GENERAL DESCRIPTION

FEATURES

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.

• Excellent Sound Quality

• Ultra-Low Input Voltage Noise: 1.6nV/ Hz at 1kHz

√

• Ultra-Low Distortion: 0.00002% at 1kHz

• Unity-Gain Stable

• Gain-Bandwidth Product: 16MHz (G = +1)

• High Slew Rate: 16V/μs

• High Open-Loop Gain: 140dB

• Low Offset Voltage: ±350μV (MAX)

• Rail-to-Rail Output

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

• Support Single or Dual Power Supplies:

3.6V to 36V or ±1.8V to ±18V

• Low Quiescent Current: 3.8mA/Amplifier

• -40℃ to +85℃ Operating Temperature Range

• Small Packaging:

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℃ to +85℃.
