SGM8543
1.1MHz, 48μA, Rail-to-Rail I/O, CMOS
Operational Amplifier with Shutdown
PRODUCT DESCRIPTION
The SGM8543 is a low cost, single rail-to-rail input and
output voltage feedback amplifier with shutdown function.
It has a wide input common mode voltage range and
output voltage swing, and takes the minimum operating
supply voltage down to 2.1V. The maximum recommended
supply voltage is 5.5V. It is specified over the extended
-40â to +125â temperature range.
The SGM8543 provides 1.1MHz bandwidth at a low
current consumption of 48μA. Very low input bias current
of 0.5pA enables the SGM8543 to be used for integrators,
photodiode amplifiers, and piezoelectric sensors.
Rail-to-rail input and output are useful to designers for
buffering ASIC in single-supply systems.
Applications for this amplifier include safety monitoring,
portable equipment, battery and power supply control,
and signal conditioning and interfacing for transducers in
very low power systems.
The SGM8543 is available in the Green SOIC-8 and
SOT-23-6 packages.
