OPA349NA

The OPA349NA is one of the OPA349 series.The OPA349NA is ultra-low power operational
amplifiers that provide 70kHz bandwidth with only 1mA quiescent current. This rail-to-rail input and output amplifier is specifically designed for battery powered applications. Unlike some micropower op amps, these parts are unity-gain stable and require no external compensation. The OPA349's low input bias current allows the use of large source and feedback resistors. The input common-mode voltage range extends 200mV beyond the power supply rails and the output swings to within 150mV of the rails, maintaining wide dynamic range.

Features of the OPA349NA are:(1)low supply current: 1ma; (2)gain-bandwidth: 70khz; (3)unity gain stable; (4)low input bias current: 10pa; (5)wide supply range: 1.8v to 5.5v; (6)input range 200mv beyond rails; (7)output swings to 150mv of rails; (8)output drive current: 20ma; (9)open-loop gain: 90db; (10)sot23 micropackages.

The absolute maximum ratings of the OPA349NA can be summarized as:(1)Supply Voltage, V+ to V : 5.5V; (2)Signal Input Terminals, Voltage(2):. (V) 0.5V to (V+) + 0.5V; (3)Current(2) :10mA; (4)Output Short Circuit(3) :Continuous; (5)Operating Temperature :55°C to +125°C; (6)Storage Temperature:65°C to +150°C; (7)Junction Temperature :150°C; (8)Lead Temperature (soldering, 3s) :300°C.If you want to know more information such as the electrical characteristics about the BF904, please download the datasheet in www.seekic.com or www.chinaicmart.com.
