SGM2358
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. www.DataSheet4U.com 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.

CAUTION
This integrated circuit can be damaged by ESD. Shengbang Micro-electronics recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
