The OPA349 (single) and OPA2349 (dual) are micro-power operational amplifiers that feature an unmatched speed/power ratio. These devices improve battery performance in portable and battery operated devices such as smoke detectors, battery packs, portable phones, pagers, and personal digital assistants (PDAs).
These rail-to-rail input and output amplifiers are unity-gain stable and require no external compensation. 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
• Low supply current: 1µA
• Gain-Bandwidth: 70kHz
• Unity Gain Stable
• Low Input Bias Current: 10pA
• Wide Supply Range: 1.8V to 5.5V
• Input Range 200mV Beyond Rails
• Output Swings TO 150mV of Rails
• Output Drive Current: 20mA
• Open-Loop Gain: 90dB
• SOT23 MicroPackages
