SGM8545

GENERAL 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.

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 a Green SOT-23-5 package. It is specified over the extended -40 to +125 temperature range.
