SGM8049-1/SGM8049-2/SGM8049-4

1.8V, 2.5µA, 120kHz,

Rail-to-Rail I/O Operational Amplifiers

GENERAL DESCRIPTION

FEATURES

The SGM8049-1, SGM8049-2 and SGM8049-4 micro

power, low voltage operational amplifiers are designed

for battery-powered applications. The amplifiers

operate on a supply voltage as low as 1.8V (±0.9V).

High-performance, single-supply operation with rail-

to-rail capability makes the SGM8049-1/2/4 useful for a

wide range of applications.

● Low Noise: 3.5μV_PP(0.1Hz to 10Hz)

● Wide Supply Voltage Range: 1.8V to 5.5V

● Low Quiescent Current: 2.5μA/Amplifier (TYP)

● Low Offset Voltage: 0.85mV (MAX)

● DC Precision:

CMRR: 100dB

PSRR: 2.5μV/V

A_OL: 118dB

In addition of small packages, the SGM8049-1/2/4

feature impressive bandwidth, low bias current and low

noise relative to the very low quiescent current.

● -40℃ to +125℃ Operating Temperature Range

● Small Packaging:
