SGM8532

SGM8531 SGM8532 SGM8534 PRODUCT DESCRIPTION The SGM8531 (single)，SGM8532 (dual) and SGM8534 (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 +125°C temperature range. The SGM8531/8532/8534 provide 500KHz bandwidth at a low current consumption of 18µA per amplifier. Very low input bias currents of 0.5 pA, enable the SGM8531/8532/8534 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 these amplifiers include safety monitoring, portable equipment, battery and power supply control, and signal conditioning and interfacing for transducers in very low power systems. The SGM8531 is available in the tiny SOT23-5 and SO-8 packages. The SGM8532 comes in the miniature SO-8 and MSOP-8 packages. The SGM8534 is offered in TSSOP-14, TSSOP-16, SO-14 and SO-16 packages. 500KHz,18µA, 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: : 500KHz • Very low input bias currents : 0.5pA • Operates on 2.1 V to 5.5 V Supplies • Input Voltage Range = - 0.1 V to +5.6 V with VS = 5.5V • Low Supply Current: 18µA/Amplifier • Small Packaging SGM8531 Available in SO-8 and SOT23-5 SGM8532 Available in SO-8 and MSOP-8 SGM8534 Available in SO-14, SO-16, TSSOP-14 and TSSOP-16 PIN CONFIGURATIONS (Top View) SGM8531 OUT -V S 1 2 4 -IN 5 +VS +IN 3 SOT23-5 SGM8531 SGM8532 8 7 6 5 NC +V S OUT NC OUT A -INA +INA -V S 1 2 3 4 8 7 6 +VS OUT B -INB APPLICATIONS ASIC Input or Output Amplifier Sensor Interface Piezo Electric Transducer Amplifier Medical Instrumentation Mobile Communication Audio Output Portable Systems Smoke Detectors Mobile Telephone Notebook PC PCMCIA cards Battery-Powered equipment NC -IN +IN -VS 1 2 3 4 NC = NO CONNECT 5 +INB SO-8 SO-8 / MSOP-8 SGM8534 SGM8534 OUT A -IN A +IN A +V S +IN B -IN B OUT B 1 2 3 4 5 6 7 14 13 OUT D -IN D OUT A -IN A +IN A +V S +IN B -IN B OUT B NC 1 2 3 4 5 6 7 8 NC = NO CONNECT 16 15 OUT D -IN D 14 +IN D 13 -V S 12 +IN C 11 10 9 -IN C OUT C NC 12 +IN D 11 -V S 10 +IN C 9 8 -IN C OUT C SO-14 / TSSOP-14 SO-16 / TSSOP-16 Shengbang Microelectronics Co, Ltd Tel: 86/451/84348461 www.sg-micro.com REV.

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. 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. ３ SGM8531/8532/8534 TYPICAL PERFORMANCE CHARACTERISTICS At TA= +25℃, VS = +5V, and RL=200kΩ connected to Vs/2,unless otherwise noted.
