SGM358

SGM321 SGM358 SGM324 PRODUCT DESCRIPTION The SGM321(single), SGM358(dual) and SGM324(quad) are rail-to-rail input and output voltage feedback amplifiers offering low cost. They have a wide input common-mode voltage range and output voltage swing, and take the minimum operating supply voltage down to 2.1V and the maximum recommended supply voltage is 5.5 V. All are specified over the extended – 40°C to +85°C temperature range. The SGM321/358/324 provide 1MHz bandwidth at a low current consumption of 60µA per amplifier. Very low input bias currents of 10pA, enable SGM321/358/ 324 to be used for integrators, photodiode amplifiers, and piezoelectric sensors. Rail-to-rail inputs and outputs are useful to designers buffering ASIC in single-supply systems. Applications for the series amplifiers include safety monitor- ing, portable equipment, battery and power supply control, and signal conditioning and interfacing for transducers in very low power systems. The SGM321 is available in SOT23-5 and SC70-5 packages. The SGM358 comes in SO-8，MSOP-8 and PDIP-8 packages. The SGM324 is offered in SO-14, TSSOP-14, TSSOP-16 and SO-16 packages. 1MHz, 60µA, Rail-to-Rail I/O CMOS Operational Amplifier FEATURES • Low Cost • Rail-to-Rail Input and Output 0.8mV Typical VOS • Unity Gain Stable • Gain Bandwidth Product: 1MHz • Very Low Input Bias Currents: 10pA • Operates on 2.1 V to 5.5 V Supplies • Input Voltage Range: - 0.1 V to +5.6 V with VS = 5.5 V • Low Supply Current: 60µA/Amplifier • Small Packaging SGM321 Available in SOT23-5 and SC70-5 SGM358 Available in SO-8, MSOP-8 and PDIP-8 SGM324 Available in SO-14, SO-16, TSSOP-14 and TSSOP-16 PIN CONFIGURATIONS (Top View) SGM321 OUT A 1 +IN 1 5 +VS -INA 2 -VS 2 +INA 3 -IN 3 4 OUT -VS 4 SGM358 8 7 +VS OUT B 6 -INB 5 +INB SOT23-5 / SC70-5 SO-8 / MSOP-8 / PDIP-8 APPLICATIONS ASIC Input or Output Amplifier Sensor Interface Piezo Electric Transducer Amplifier Medical Instrumentation Mobile Communication Audio Output Portable Systems Smoke Detectors Notebook PC PCMCIA cards Battery –Powered equipment DSP interface OUT A -IN A +IN A +VS +INB -INB OUT B NC 1 2 3 4 5 6 7 8 SGM324 16 OUT D 15 -IND 14 +IND 13 -VS 12 +INC 11 -INC 10 OUT C NC = NO CONNECT SGM324 OUT A -IN A +IN A +VS +INB -INB OUT B 1 2 3 4 5 6 7 14 OUT D 13 -IND 12 +IND 11 -VS 10 +INC 9 8 -INC OUT C 9 NC TSSOP-16 / SO-16 TSSOP-14/SO-14 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. NOTES 1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ３ SGM321/358/324 TYPICAL PERFORMANCE CHARACTERISTICS At TA = +25℃, VS = +5V, and RL = 100kΩ connected to Vs/2,unless otherwise noted.
