SGM8249-1/SGM8249-2

8MHz, High Voltage, High Precision, Low Noise,

Rail-to-Rail Output Operational Amplifiers

GENERAL DESCRIPTION

FEATURES

The single SGM8249-1 and dual SGM8249-2 are high

voltage, low noise and high precision operational

amplifiers which can operate from 4.5V to 36V single

supply or from ±2.25V to ±18V dual supplies. These

devices provide rail-to-rail output operation.

● Low Offset Voltage: 10μV (MAX)

● Open-Loop Voltage Gain: 150dB (TYP)

● PSRR: 150dB (TYP)

● CMRR: 140dB (TYP)

● Input Voltage Noise Density: 10nV/ Hz at 1kHz

√

● Gain-Bandwidth Product: 8MHz

● Overload Recovery Time: 0.7μs

● Rail-to-Rail Output Swing

The SGM8249-1/2 offer a low offset voltage less than

10μV and a low bias current. The combination of

characteristics makes the SGM8249-1/2 good choices

for temperature measurements, pressure and position

sensors, strain gauge amplifiers and medical

instrumentation, or any other 4.5V to 36V applications

requiring precision and long-term stability.

● Support Single or Dual Power Supplies:

4.5V to 36V or ±2.25V to ±18V

● Low Supply Current: 0.85mA/Amplifier (TYP)

● -40℃ to +125℃ Operating Temperature Range

● Small Packaging:

The SGM8249-1 is available in Green SOT-23-5 and

SOIC-8 packages. The SGM8249-2 is available in a

Green SOIC-8 package. The SGM8249-1/2 are rated

over the -40℃ to +125℃ temperature range.
