SGM8545
1.1MHz, 48μA, Rail-to-Rail I/O
CMOS Operational Amplifier
PRODUCT DESCRIPTION
The SGM8545 is a low cost, single rail-to-rail input and
output voltage feedback amplifier. 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 -40℃ to +125℃
temperature range.
The SGM8545 provides 1.1MHz bandwidth at a low
current consumption of 48μA. Very low input bias current
of 0.5pA enables SGM8545 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 SGM8545 is available in the Green SOT-23-5
package.
