15MHz, High Output Drive, High Precision,

Low Noise Operational Amplifiers

GENERAL DESCRIPTION

FEATURES

The SGM8557-1 (single), SGM8557-3 (single with

shutdown), SGM8557-2 (dual) and SGM8557-5 (dual

with shutdown) are low noise, high precision CMOS

operational amplifiers that provide a high output current

of 240mA, rail-to-rail output operation from a range of

2.7V to 5.5V single supply. The SGM8557-3/5 are both

available with shutdown pins that drive the output

voltage low.

• Output Drive Capability: 240mA

• Low Input Offset Voltage: 5μV (MAX)

• Low Input Offset Voltage Drift: 27nV/℃ (TYP)

• Low Noise: 30nV/ Hz at 1kHz

√

• Gain-Bandwidth Product: 15MHz

• High Slew Rate: 7V/μs

• High Open-Loop Gain (R_L= 2kΩ): 144dB

• Power Supply Rejection Ratio: 120dB

• Over-Temperature Protection

The SGM8557-1/2/3/5 offer low input offset voltage,

low input offset voltage drift and high output current

drive. These devices also can achieve a high 15MHz

gain-bandwidth product and a high 7V/μs slew rate.

• No Phase Reversal for Overdriven Inputs

• Rail-to-Rail Input and Output

• Supply Voltage Range: 2.7V to 5.5V

• Quiescent Supply Current:

The SGM8557-1/2/3/5 are specifically designed to

drive high current load, such as 32Ω headset, V_BIASof

RF power amplifier, etc.

1.2mA/Amplifier (TYP)

SGM8557-3/5

• -40℃ to +125℃ Operating Temperature Range

• Small Packaging:

The SGM8557-1 is available in Green SOIC-8,

MSOP-8 and SOT-23-5 packages. The SGM8557-2 is

available in a Green SOIC-8 package. The SGM8557-3

is available in Green SOIC-8 and SOT-23-6 packages.

The SGM8557-5 is available in a Green MSOP-10

package. They operate over an ambient temperature

range of -40℃ to +125℃.
