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. 1MHz, General Purpose CMOS Operational Amplifier FEATURES • Low Cost • Rail-to-Rail Output 1.7mV Typical VOS • Unity Gain Stable • Gain Bandwidth Product: 1MHz • Very Low Input Bias Currents: 10pA • Input Common-Mode Voltage Range Includes Ground • Operates from 3 V to 5.5 V • Small Packaging: SO-8 APPLICATIONS ASIC Input or Output Amplifier Sensor Interface Piezo Electric Transducer Amplifier Medical Instrumentation Mobile Communication Portable Systems Smoke Detectors Notebook PC PCMCIA cards Battery –Powered equipment DSP interface PIN CONFIGURATION (Top View) SGM2358 OUT A 1 -INA 2 +INA 3 -VS 4 8 7 +VS OUT B 6 -INB 5 +INB SO-8 Shengbang Microelectronics Co, Ltd Tel: 86/451/84348461 www.sg-micro.com REV.

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.
