PRODUCT DESCRIPTION
The SGM2358 has dual rail-to-rail output voltage
feedback amplifiers in one package. It takes the
minimum operating supply voltage down to 3V and
the maximum recommended supply voltage is 5.5 V.
SGM2358 is specified over the extended -40°C to +85°C
temperature range.
The amplifier in SGM2358 provides 1MHz bandwidth,
Very low input bias currents of 10pA, these features
enable SGM2358 to be used for integrators, photodiode
amplifiers, and piezoelectric sensors. Rail-to-rail output
feature is useful for designers to buffer ASIC in
single-supply systems.
Applications of SGM2358 include safety monitoring,
portable equipment, battery and power supply control,
signal conditioning and interfacing for transducers in
low power systems.
The SGM2358 comes in SO-8 package.
